Detailed Description
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of an ultrasonic image measurement information editing method according to an embodiment of the invention, the method can be applied to an ultrasonic diagnostic apparatus, and the method includes the following steps:
s101, drawing measurement information on an ultrasonic image according to a measurement information drawing instruction.
The measurement information drawing instruction may be an instruction for drawing measurement information, such as an instruction for drawing measurement information such as a trace, a straight line segment, an angle line, and a text, which is input by a user through an input device.
After the measurement information drawing instruction is obtained, the measurement information can be drawn on the measurement layer of the ultrasonic image. The measurement information comprises at least one measurement type of trace lines, straight line segments, angle lines and characters. The measurement information may be plotted on a measurement map layer on an ultrasound image.
For example, the measurement information may specifically include measurement movie data, REF data, long axis measurement primitive data, horizontal axis measurement primitive data, measurement result data, measurement% a,% D calculation data, which are organized in a manner to form a measurement information hierarchy as shown in fig. 2 (a).
The terms related to fig. 2 (a) are as follows:
measurement data management: measuring data access and modifying an entry;
measuring a cursor factory: creating measuring cursors of all measuring types, and selecting measuring cursors objects (such as 3 measuring cursors) according to the current measuring type;
measuring primitive factories: creating measurement primitives (the content is empty and is equivalent to a template) of all measurement types, and selecting corresponding measurement templates (5 kinds of measurement primitives) according to the measurement types created by a user;
movie measurement data list: because the measurement module can load a plurality of film-related measurement information at the same time; so there is a list to manage measurement information inside different movies;
measuring REF data: a movie has only a unique identifier (REF: reference object of the calculation result), so a movie has only 1 REF identifier;
measuring long axis data: a movie contains only one long axis image area, so there is only one long axis measurement data;
list of measured cross-section data: a movie contains a plurality of frames of images, so that image frame measurement information is distinguished by frame number;
measuring a long axis primitive list: the number of measurements made by a movie of the long axis image region;
measurement result data: measurement result data on a certain frame image of one movie;
measuring calculation result data: measurement calculations on a frame of an image of a film;
measurement calculation type: a, calculating the area ratio of the current object relative to the REF object; d, calculating the ratio of the length and the diameter of the current object relative to the REF object;
list of measurement cross-section primitives: the number of measurements made over the cross-sectional image area of a film;
measuring the graphic element: different measurement primitives are distinguished according to measurement types, and the measurement primitives describe the drawing method, the measurement result style, the measurement result calculation mode, the measurement line color, the line width, the line type and the measurement label of the primitives of the type;
measuring primitive types: cross-sectional distance measurement (distance measurement in any direction); long-axis distance measurement (distance measurement in the vertical direction); using the same measuring cursor;
angle measurement (three-point determination of angle); configuring an angle measurement cursor and an angle measurement editing cursor;
manual tracing (curve outline tracing); automatic tracing (algorithmically calculated curve profile); this manual trace and automatic trace may use the same measuring cursor;
that is, in the present embodiment, a total of 4 measurement types (e.g., distance measurement, angle measurement, manual tracing, automatic tracing) may be included; may include 5 measurement primitive types (e.g., cross-sectional distance measurement primitive, long-axis distance measurement primitive, angle measurement primitive, manual tracing measurement primitive, automatic tracing measurement primitive); can include 3 types of measuring cursors (such as a linear measuring cursors, an angle measuring cursors, a tracing measuring cursors);
measurement information hierarchy:
the measurement information of one movie includes: the film long axis region measurement information, the film cross section region measurement information of each frame and the REF object selected by the film;
each frame of measurement information includes: measurement results, measurement calculation results, cross-section measurement primitive list (representing the number of measurements completed) on the image frame;
the minimum unit of measurement information is a measurement primitive, but due to the complexity of intravascular image presentation, the measurement information is organized and managed according to the hierarchical structure of movies.
And S102, when a measurement information confirmation instruction is received, exiting the editing mode of the measurement information, and storing the measurement information as standard measurement information.
The measurement information confirmation instruction may specifically be a confirmation instruction that the user determines that the editing of the measurement information is completed by controlling the input device after determining that the currently drawn measurement information meets the requirement. For example, the user clicks a button for confirming that editing of the measurement information is completed, or the user clicks save measurement information.
And when receiving the measurement information confirmation instruction, exiting the editing mode of the measurement information. The editing mode is a mode for drawing and adjusting the measurement information.
The standard measurement information may include any one or more of measurement type of the measurement information, position coordinates of the measurement information relative to the ultrasound image, measurement values, other parameters, and other data (where the position coordinates may be coordinate values under a rectangular coordinate system on the ultrasound image, or may be other coordinate systems, an origin of the coordinate system may be a geometric center of the ultrasound image or a vertex of any angle, or may be a custom point, and coordinate precision may be defined by using pixel points); the standard measurement information may be in a unified storage format (the value of a certain measurement type may be null if the data does not contain any item of data) which is commonly used for any information type, and may be changed according to different types. For example, when the measurement type is a trace, the standard measurement information may include the location coordinates of all the feature points or only the location coordinates of all the feature points; when the measurement type is a straight line segment, the standard measurement information can comprise the position coordinates of the straight line segment and two end points of the straight line segment, and can also comprise the length (namely a measurement value) of the straight line segment; when the measurement type is an angle line, the standard measurement information can comprise the measurement type such as the angle line, the angular vertex position coordinate, the two-side arbitrary point position coordinate, the angle value and the like; when the measurement information is text (e.g., a doctor marks a name of a biological structure), the standard measurement information may include location coordinates, text content, text number, etc. of the type of measurement that is text, a text center point (or any feature point). The content of the standard measurement information storage is not limited to the above-described example, and a flexible selection may be adopted in practice according to the function of the ultrasonic diagnostic apparatus, the needs of the user, and the like.
And S103, when a measurement information activation instruction is received, reading standard measurement information and analyzing the standard measurement information into measurement information, so that the measurement information enters an editing mode again.
The measurement information activation instruction may be specifically an activation instruction for the user to restart the editing mode of the measurement information after exiting the ultrasonic image measurement information editing mode, such as clicking a re-editing button, or moving a cursor onto the measurement information to perform click activation. Of course, the measurement information activation instruction may also start an activation instruction of the editing mode of the measurement information when the ultrasound image is opened again, for example, when callback, the measurement information is found to be wrong or missing and needs to be edited again, and then the measurement information editing mode is entered again.
Reading standard measurement information and analyzing the standard measurement information into measurement information, enabling the measurement information to enter an editing mode again, specifically, reading the standard measurement information, displaying a drawing image on an ultrasonic image as the measurement information, starting a corresponding processing program to read user operation and analyzing the user operation as a user operation instruction, and enabling the measurement information to enter the editing mode again. And reading standard measurement information, and drawing and displaying the measurement information on the ultrasonic image again, wherein the measurement information can be regarded as the inverse process of the measurement information storage process.
Specifically, if the standard measurement information is stored, converting the standard measurement information into a binary file by using a serialization technology and storing the binary file; accordingly, the reading of standard measurement information may be specifically: the binary file is read and converted to standard measurement information using an anti-serialization technique. Among them, serialization technology (Serialization) is a process of converting state information of an object into a form that can be stored or transmitted. During serialization, the current state of the measurement information may be written to a temporary or persistent storage area. Later, the measurement information may be recreated by reading or de-serializing the state of the object from the storage area. Anti-serialization techniques: reading object state information from the storage area and constructing an object; there are many well-established schemes for serialization and deserialization techniques, such as Json/XML, protobuf, boost, serialization. Referring to FIG. 4, boost serialization is employed to implement the store callback.
Preferably, when the standard measurement information includes a measurement type of the measurement information, the corresponding processing program may be started to display the measurement information and/or analyze the user operation instruction according to the measurement type analyzed when the standard measurement information is read. The processing program can change the display effect of measurement information and/or other elements (such as a cursor) on the operation interface according to the measurement type, and can also determine the processing task to be executed according to the preset relation between the user operation instruction and the processing task under the measurement type. For example, when the measurement type is a trace, the handler may click on a particular location coordinate from the key, determining that the processing task to be performed is to fit a new trace based on that location coordinate; when the measurement type is a straight line segment, the processing program can click any one end point of the straight line segment according to the key, determine that the processing task to be executed is to enable the end point to enter a movable state, change the position of the end point according to the cursor position movement and change the length and/or direction of the straight line segment.
Considering that the existing measurement storage is to solidify measurement information on an ultrasonic image, the measurement information and the ultrasonic image are stored in a screen capture file mode, and the screen capture file is taken as a whole picture, so that the requirements of subsequent re-measurement, re-editing and the like are difficult to meet. Based on this, the method stores the measurement information individually in the form of standard measurement information when exiting the edit mode of the measurement information. Upon receiving the measurement information activation instruction, standard measurement information may be read, and the edit mode may be entered again. The requirement of re-editing the measurement information under the scene such as callback can be met.
It should be noted that, based on the above embodiments, the embodiments of the present invention further provide corresponding improvements. The preferred/improved embodiments relate to the same steps as those in the above embodiments or the steps corresponding to the steps may be referred to each other, and the corresponding advantages may also be referred to each other, so that detailed descriptions of the preferred/improved embodiments are omitted herein.
Preferably, in this embodiment, in order to be able to enter the editing mode of the measurement information again, the measurement information needs to be stored as standard measurement information while exiting the editing mode of the measurement information, and when a measurement information activation instruction is received, the standard measurement information is read and parsed into the measurement information, so that the measurement information enters the editing mode again. Specific implementations include, but are not limited to, the following:
in the above step S101, storing the measurement information as standard measurement information may specifically include: converting the measurement information into standard measurement information corresponding to the standard position coordinates by utilizing a conversion function in combination with conversion parameters determined according to the corresponding relation between the position coordinates of the ultrasonic image and the standard position coordinates;
accordingly, in the step S103, the reading of the standard measurement information and the analysis of the standard measurement information into the measurement information may specifically include: and reading standard measurement information, and reversely converting the standard measurement information into measurement information by utilizing a conversion function and combining conversion parameters.
Wherein, the conversion parameter is the corresponding relation between the position coordinates of the ultrasonic image and the standard coordinates, and the conversion parameter can specifically comprise at least one parameter of scaling, offset and rotation. The conversion function is a function that scales, offsets and rotates the measurement information according to the conversion parameters.
That is, when storing the measurement information as the standard measurement information, a conversion parameter may be determined by using a conversion function in combination with the correspondence of the position coordinates of the overspeed image and the standard position coordinates, and then the measurement information is converted into the standard measurement information corresponding to the standard position coordinates based on the conversion parameter. That is, the position coordinates of the measurement information are stored corresponding to the value standard position coordinates.
Specifically, considering that when the measurement information is stored, the corresponding ultrasound image may not be a standard ultrasound image (i.e., an ultrasound image under a non-standard position coordinate, for example, the standard position coordinate is displayed in a full screen, and the current ultrasound image is displayed in a non-full screen), so the measurement information is converted into the standard measurement information corresponding to the standard position coordinate and then stored. The conversion parameters include rotation parameters, scaling parameters and offset parameters. In this embodiment, the standard format conversion parameters include a rotation parameter, a scaling parameter and an offset parameter, but specific values of the three parameters are not limited thereto. That is, when the format of the ultrasound image is consistent with that of the standard ultrasound image, i.e., the size, direction (or angle), and display position are all consistent, the rotation parameter, the scaling parameter, and the offset parameter may all be 0; of course, when there is a size difference between the ultrasound image and the standard ultrasound image, the scaling parameter corresponds to the size ratio between the ultrasound image and the standard ultrasound image; when the angle difference exists between the ultrasonic image and the standard ultrasonic image, the rotation parameter is the angle difference between the ultrasonic image and the standard ultrasonic image; when there is a positional difference between the ultrasound image and the standard ultrasound image, then the offset parameter is the amount of positional offset between the ultrasound image and the standard ultrasound image (e.g., at least one of lateral and longitudinal offset is not zero).
Further, in view of practical application, in the process of displaying an ultrasound image, zooming, rotating, switching display positions, and the like are required. In order to enable the measurement information corresponding to the numbered ultrasonic images to be changed along with the change of the images, the measurement information can be edited again. In the process of realizing the re-editing of the measurement information, the following operations can be performed:
when the ultrasonic image is changed into a target ultrasonic image, the conversion parameters are synchronously changed into target conversion parameters according to the change relation of the ultrasonic image; accordingly, the inverse conversion of standard measurement information into measurement information by using a conversion function in combination with conversion parameters includes: converting the measurement information into target standard measurement information corresponding to the standard position coordinates by combining a conversion function with the target conversion parameter; accordingly, reading standard measurement information and analyzing the standard measurement information into measurement information, including: and reading target standard measurement information, and reversely converting the target standard measurement information into measurement information by combining a conversion function with a target conversion parameter.
Because the ultrasound image change mainly comprises rotation, scaling and offset, the ultrasound image change is a target ultrasound image, and at least one of rotation, scaling and offset is performed on the ultrasound image, and accordingly, the target conversion parameter is a conversion parameter processed corresponding to the change parameter in the rotation parameter, scaling parameter and offset parameter.
Preferably, the standard measurement information further includes a measurement type of the measurement information; correspondingly, when the measurement information activation instruction is received, the measurement type is analyzed, and a corresponding processing program is started to display the measurement information and/or analyze the user operation instruction. Therefore, when the standard measurement information is analyzed, the specific type of the measurement information can be determined, and when the editing mode of the measurement information is performed again, the processing program corresponding to the measurement information can be started to display the measurement information, or the user operation instruction is analyzed, or the processing program corresponding to the measurement information is started to display the measurement information and analyze the user operation instruction. For example, when the standard measurement information stores a trace of the measurement type, a trace editing process program is started to display a trace corresponding to the measurement information, and a user operation instruction is identified so as to re-edit the trace.
In order to facilitate a person skilled in the art to better understand the method for editing ultrasonic image measurement information provided by the embodiment of the present invention, the method for editing ultrasonic image measurement information is described in detail below in conjunction with several common specific application scenarios.
Application scenario one:
the measurement information is stored as standard measurement information, and can be used for carrying out editing mode again on the measurement information under the circumstance of coping with ultrasonic image change. Specifically, referring to fig. 2 (b), the method for editing ultrasonic image measurement information in the present invention includes the following steps:
s201, drawing measurement information on the ultrasonic image A0 according to the measurement information drawing instruction.
And S202, when a measurement information confirmation instruction is received, exiting the editing mode of the measurement information, acquiring a conversion parameter A0, carrying the conversion function to convert the position coordinate of the measurement information relative to the ultrasonic image A0 into a standard position coordinate, and storing the standard position coordinate into the standard measurement information.
The conversion function is calculated according to the conversion parameters, and when the ultrasonic image changes, the conversion parameters synchronously change according to the change relation of the ultrasonic image.
In general, changing the display state of an ultrasound image according to a user operation instruction includes: scaling and shifting of the ultrasound image, among other things, is embodied in changing the normally displayed ultrasound image to one of a plurality of displayed modes. Thus, preferably, the conversion parameters include a rotation parameter, a scaling parameter, and an offset parameter, which are synchronously changed according to the changing relationship of the ultrasound image. For example, the rotation parameter may be defined in terms of an angle, which also changes by the same angle when the ultrasound image is rotated by a particular angle; similarly, the scaling parameters may be defined in terms of scaling and the offset parameters may be defined in terms of pixels, all of which produce a synchronized, equivalent number of changes following the changes in the ultrasound image. By adopting the above definition, when the measurement information is stored as the standard measurement information, since the ultrasound image is unchanged, the conversion parameter can be made to be the initial conversion parameter (for example, the rotation parameter is 0, the scaling parameter is 1, and the offset parameter is 0), and the conversion function converts the position coordinate of the measurement information with respect to the ultrasound image A1 into the standard position coordinate by using the initial conversion parameter.
The standard measurement information may be specifically measurement information after converting the measurement information into a measurement standard format. Wherein the measurement standard format is a custom format, and can measure information P0
(x 0, y 0) is a standard reference frame relative to the single image position S0, and for any image position S, the measurement point P (x, y) on the image needs to go through a conversion function
Converted to a point P0 (x 0, y 0) standard format. As in fig. 3, a schematic diagram of the measurement transformation during callback is stored.
The method can specifically adopt an anti-serialization technology to read the measurement binary file into the memory and convert the measurement binary file according to the image parameters; callback requires passing the standard format measurement point P0 (x 0, y 0) through a conversion function according to the image parameters (translation, rotation angle, scaling)
And converting into a display format measurement point P (x, y). Wherein: />
A translation amount; θ→rotation angle; gamma→scaling.
It can be seen that in this embodiment, the standard measurement information includes standard position coordinates. Of course, the standard measurement information may also include other data as in the previous embodiments, so that other steps or procedures may be performed using such data.
S203, detecting that the ultrasonic image A0 is changed into the ultrasonic image A1, and synchronously changing the conversion parameter A0 into the conversion parameter A1.
User manipulation causes the ultrasound image to change (e.g., zoom, offset, rotate), and the conversion parameters change synchronously according to the relationship of the ultrasound image changes.
S204, when a measurement information activation instruction is received, reading standard measurement information, using a conversion parameter A1 to bring a conversion function, reversely converting standard position coordinates into target position coordinates, converting the standard measurement information into target measurement information, drawing and displaying the target measurement information on an ultrasonic image A1, and enabling the target measurement information to enter an editing mode again.
When the standard measurement information is converted into the target measurement information, the standard position coordinates are converted into the target position coordinates, and if the standard measurement information comprises other data besides the standard position coordinates, whether the other data are converted or not can be adjusted according to actual conditions. For example, the standard measurement information further includes a measurement type, and when the measurement information is converted into the standard measurement information and the standard measurement information is converted into the target measurement information, the measurement type may not be converted. Of course, if the standard measurement information contains other data that needs to be changed as the ultrasound image changes, the corresponding conversion rules should be formulated.
In step S204, the measurement storage callback procedure may be regarded as a specific implementation procedure of the measurement storage callback is shown in fig. 5. Therefore, the callback of the measurement information can be realized, namely, the editing mode of the measurement information is started for the second time, and the editing requirement of the measurement information in the callback process is met.
And (2) an application scene II:
after the ultrasonic image is changed, a reediting mode of the measurement information is entered on the changed ultrasonic image. Specifically, please refer to fig. 2 (c), the method for editing ultrasonic image measurement information in the present invention includes the following steps:
s301, detecting that the ultrasonic image B0 is changed into an ultrasonic image B1, and synchronously changing the conversion parameter B0 into a target conversion parameter B1.
At this time, the user changes the ultrasound image before drawing the measurement information, for example, the user considers that the measurement is inconvenient, and changes the ultrasound image B0 to the ultrasound image B1 by rotating the ultrasound image B0 by a certain angle.
S302, drawing measurement information on the ultrasonic image B1 according to the measurement information drawing instruction.
And S303, when a measurement information confirmation instruction is received, exiting the editing mode of the measurement information, acquiring a conversion parameter B1, carrying the conversion function to convert the position coordinate of the measurement information relative to the ultrasonic image B1 into a standard position coordinate, and storing the standard position coordinate into the standard measurement information.
S304, when a measurement information activation instruction is received, reading standard measurement information, using a conversion parameter B1 to bring a conversion function, reversely converting standard position coordinates into target position coordinates, converting the standard measurement information into target measurement information, drawing and displaying the target measurement information on an ultrasonic image B1, and enabling the target measurement information to enter an editing mode again.
And (3) an application scene III:
dynamically monitoring the change of the ultrasonic image, and dynamically entering a reediting mode of the measurement information on the dynamically changed ultrasonic image. Specifically, referring to fig. 2 (d), the method for editing ultrasonic image measurement information in the present invention includes the following steps:
