Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The current blood flow gain adjustment scheme can only adjust the overall gain of blood flow, cannot adjust local focuses more finely, and also can adjust the gains of different focuses respectively, for example: if there are two lesions: when the gain is increased to see the blood flow of the lesion 1, the lesions 1 and 2 may have excessive gain of the other lesion 2, which may cause blood overflow or blood flow loss. Or when the blood flow gain of the lesion 1 is too large and needs to be reduced, the blood flow gain of the lesion 2 is also reduced, and the situation that the blood flow gain of the lesion 2 is too small and the blood flow is insufficient may occur.
It can be seen that, because the current blood flow gain adjustment mode can only adjust the whole blood flow gain and can not adjust the local blood flow gain, the diagnosis of doctors is greatly influenced; therefore, the invention discloses a blood flow gain adjusting method, a blood flow gain adjusting device, blood flow gain adjusting equipment and a computer readable storage medium, so as to adjust local blood flow gain, avoid the problems of blood flow insufficiency or blood flow overflow and the like of a blood flow image, and enable the blood flow image to be more beneficial to observation and diagnosis.
It should be noted that the gain is an ultrasonic term, and the magnitude of the ultrasonic signal value can be changed, and if the gain is increased, the ultrasonic signal value becomes larger, and if the gain is decreased, the ultrasonic signal value becomes smaller. In each mode, there is a concept of corresponding gain, for example, gain in a two-dimensional mode, blood flow gain in a blood flow mode, and the like. Referring to fig. 1, a schematic structural diagram of a regulating system according to an embodiment of the present invention is shown; the Color knob in fig. 1 is a blood flow knob, and the gain in the frame of the whole dark gray portion including the lesion 1 and the lesion 2, i.e., the blood flow ROI (region of interest) is controlled. When the blood flow knob is rotated, the overall gain of the dark gray portion is changed, and the blood flow gain of the lesion 1 or the lesion 2 cannot be adjusted individually.
Referring to TGC (Time Gain Control, Time Gain compensation) slider adjustment buttons in fig. 1, TGC is a general name of a row of 8 sliding buttons on the Control panel of the ultrasound system, the TGC divides the current scanning Depth into 8 equal parts, and each slider corresponds to equal parts of ultrasound signals, and sequentially goes from the minimum Depth to the maximum Depth. As the slider position is moved, the ultrasound signal at the corresponding depth position changes in magnitude, i.e., the TGC is associated with the ultrasound signal at the corresponding depth. LGC (Lateral gain Gontrol) is a generic term for a row of 8 sliding buttons on a touch screen or control panel, and divides the current scanning width (angle) into 8 equal parts, and each slider corresponds to equal parts of the ultrasonic signal, sequentially from the leftmost to the rightmost of the scanning width. By moving the slider position, the ultrasonic signal at the corresponding width position changes in magnitude, which can be understood as the LGC being associated with the ultrasonic signal at the corresponding width.
The blocks represented by TGC and LGC in fig. 1 are controllable gain ranges according to the present invention, and the gain of any region in the ROI box of blood flow can be controlled by combination.
The existing TGC slider is only related to the depth direction of the ultrasonic signal of the two-dimensional image at present, and the gain of the two-dimensional image in different depth directions can be adjusted, namely: the existing scheme can only adjust the brightness of an image in a B mode, 8 slide block buttons are listed on a control panel and can move left and right, the gain is reduced by moving left, and the gain is increased by moving right. While in the blood flow mode, the TGC is moved, still changing the two-dimensional gain. Similarly, the existing LGC module is only related to the width direction of the ultrasound signal of the two-dimensional image, and the gain of the two-dimensional image in different width directions can be adjusted. Currently, 8 slider buttons are mostly listed on a touch screen, and can move up and down, so that the gain is increased by moving up and the gain is decreased by moving down, and the touch screen does not have the parameter in the blood flow mode.
Referring to fig. 2, a flow chart of a blood flow gain adjustment method according to an embodiment of the present invention is schematically illustrated; the blood flow gain adjustment method may include:
s101, acquiring TGC gain adjustment information and LGC gain adjustment information; wherein the TGC gain adjustment information comprises: TGC identification information and a TGC gain adjustment command, the LGC gain adjustment information including: LGC identification information and an LGC gain adjustment instruction; a first region association relation exists between different TGC identification information and display regions in different blood flow signal depth directions, and a second region association relation exists between different LGC identification information and display regions in different blood flow signal width directions; adjusting association relations exist among different TGC gain adjusting instructions, different LGC gain adjusting instructions and blood flow gain;
the blood flow gain adjustment method according to the present invention is mainly suitable for adjusting the gain of a blood flow image in a two-dimensional + blood flow mixed mode, which may also be referred to as a blood flow mode (color mode). If the blood flow gain adjustment method described in this embodiment is applied for the first time, the area association relationship needs to be preset, that is: associating different TGC identification information with display areas in different blood flow signal depth directions one by one in advance to obtain a first area association relationship, and associating different LGC identification information with display areas in different blood flow signal width directions one by one to obtain a second area association relationship; and, it is also necessary to set an adjustment association relationship, that is: and presetting the association relation among different TGC gain adjustment commands, different LGC gain adjustment commands and the blood flow gain.
The TGC gain adjustment information is adjustment information triggered when a user triggers the TGC slider adjustment button, and comprises TGC identification information and a TGC gain adjustment instruction, so that the user can know whether the user slides the TGC slider adjustment button on the left or slides the TGC slider adjustment button on the right through the TGC gain adjustment instruction and a preset adjustment association relation, and the TGC gain adjustment information is generated by triggering the TGC slider adjustment button, so that the adjustment information is bound to carry the TGC identification information, and the TGC slider adjustment button can be clearly determined through the TGC identification information. Referring to fig. 1, the identification information of the TGC slider adjustment button located on the left side of the picture may be set to: TGC slider 1, TGC slider 2, … …, TGC slider 8.
Also, the LGC gain adjustment information is adjustment information that is triggered when a user triggers an LGC slider adjustment button, and includes: the LGC gain adjustment information is generated by triggering the LGC slider adjustment button, so that the LGC gain adjustment information inevitably carries the LGC identification information, and which LGC slider adjustment button the user adjusts can be clearly determined by the LGC identification information. Referring to fig. 1, the identification information of the LGC slider adjustment button located at the upper side of the picture may be set to: LGC slider 1, LGC slider 2, … …, LGC slider 8.
It should be noted that, in this solution, the number of TGC identification information carried by the TGC gain adjustment information is not limited, and the number of LGC identification information carried by the LGC gain adjustment information is also not limited, and a user may dynamically select a slider to be adjusted according to the size of a local blood flow image that needs to be adjusted in actual operation, so that the number of TGC identification information carried by the TGC gain adjustment information may be one or multiple, and the number of LGC identification information carried by the LGC gain adjustment information may also be one or multiple.
For example, referring to fig. 1, when adjusting a lesion 1, it is necessary to adjust a TGC slider 1, a TGC slider 2, and a TGC slider 3, and thus TGC identification information carried by the generated TGC gain adjustment information includes three identification information, namely, the TGC slider 1, the TGC slider 2, and the TGC slider 3; similarly, when the lesion 1 is adjusted, the LGC slider 3 and the LGC slider 4 also need to be adjusted, and therefore, the LGC identification information carried by the generated LGC gain adjustment information includes two identification information, namely, the LGC slider 3 and the LGC slider 4; accordingly, lesion 2 also requires adjustment of multiple TGC and LGC sliders, which is not specifically illustrated herein.
S102, determining a region to be adjusted corresponding to TGC identification information and LGC identification information in the blood flow image by utilizing the first region association relation and the second region association relation;
after the TGC identification information is identified, the depth direction area and the width direction area to be adjusted can be determined through the preset first area incidence relation and second area incidence relation; after the depth direction area to be adjusted and the width direction area to be adjusted are determined, the area to be adjusted can be identified from the whole blood flow image according to the intersection of the area to be adjusted, and the blood flow image corresponding to the area to be adjusted is a local blood flow image. For example, referring to fig. 1, if the TGC identification information includes TGC slider 1, TGC slider 2, and TGC slider 3, and the LGC identification information includes LGC slider 3 and LGC slider 4, it can be seen from the region corresponding to each slider that the region to be adjusted is the blood flow image region including the lesion 1.
S103, adjusting the blood flow gain of the area to be adjusted according to the TGC gain adjusting instruction, the LGC gain adjusting instruction and the adjusting correlation.
In this embodiment, the adjustment association relationship between the TGC gain adjustment command and the LGC gain adjustment command and the blood flow gain is preset, so that in the blood flow mode, the TGC gain adjustment command is associated with the depth direction of the blood flow signal and is not associated with the two-dimensional signal, so that in the blood flow mode, the TGC gain adjustment information can be generated by adjusting the TGC slider to control the gain of the blood flow image in different depth directions, and the association relationship between the TGC gain adjustment command and the blood flow gain in the adjustment association relationship can be: if the TGC gain adjustment command is a command for moving the TGC slider to the left, the blood flow gain is reduced, and if the TGC gain adjustment command is a command for moving the TGC slider to the right, the blood flow gain is increased.
Similarly, the LGC gain adjustment instruction is associated with the width direction of the blood flow signal, and is not associated with the two-dimensional signal, so that in the blood flow mode, the LGC gain adjustment instruction can be generated by adjusting the LGC slider, and the gain of the blood flow image in different width directions is controlled, and then the association relationship between the LGC gain adjustment instruction in the adjustment association relationship and the blood flow gain may be: if the LGC gain adjustment instruction is an instruction to move up the LGC slider, the blood flow gain is increased, and if the LGC gain adjustment instruction is an instruction to move down the LGC slider, the blood flow gain is decreased.
When the gain is adjusted, the larger the gain is, the more blood flows in the blood flow image of the region are, and conversely, the less blood flows are. When the blood flow gain of the region to be adjusted is adjusted, the blood flow signal of the region to be adjusted can be adjusted according to a preset adjustment rule. That is, when the gain is adjusted by the TGC gain adjustment command and the LGC gain adjustment command, the working principle of most ultrasound systems is the same, namely: after adjusting information corresponding to TGC and LGC position data is transmitted to an ultrasonic system, mathematical operation is carried out on blood flow signals of a region to be adjusted through a preset adjusting rule, wherein the adjusting rule can be a multiplication algorithm, an addition algorithm, a power algorithm, a logarithm algorithm and the like; if the LGC slider is moved downward, the corresponding blood flow signal can be reduced by adjusting the rule, i.e., the gain is reduced.
It can be seen that, in the scheme, through the combination of the lateral direction and the longitudinal direction of the TGC and the LGC, the gain of any region of the blood flow image can be freely adjusted, and the optimization of the local blood flow gain is realized. For example, referring to fig. 1, it is of interest to the physician for lesion 1 and lesion 2 in fig. 1, and the other parts are regions of no interest; therefore, the blood flow gain of the focus area can be improved by increasing the slide block corresponding to the dotted line in the graph, so that the effect of focus blood flow display is enhanced; meanwhile, the sliders of other non-interested areas can be adjusted down, so that the gain of the non-interested areas can be reduced, and the noise of the non-interested areas can be controlled.
Therefore, by the gain adjusting method, the gains of the focus 1 and the focus 2 can be independently adjusted to be high, the gains of the non-interested regions are adjusted to be low, so that the blood flow of the focus is enhanced, the blood flow noise of the non-interested regions of other non-focuses is inhibited, the signal to noise ratio of the finally obtained blood flow image is higher, the blood flow image obtained by the focus blood flow is clearer than that obtained by the original gain integrally adjusting scheme, and the blood flow noise of the tissue region is smaller.
Referring to fig. 3, a schematic flow chart of another blood flow gain adjustment method according to an embodiment of the present invention is shown; in this embodiment, the same parts of the blood flow gain adjustment method and the blood flow gain adjustment method described in the previous embodiment may be referred to each other, and are not described in detail herein.
The blood flow gain adjustment method may include:
s201, acquiring TGC gain adjustment information and LGC gain adjustment information; wherein the TGC gain adjustment information includes: TGC identification information and a TGC gain adjustment command, the LGC gain adjustment information including: LGC identification information and an LGC gain adjustment instruction; a first region association relation exists between different TGC identification information and display regions in different blood flow signal depth directions, and a second region association relation exists between different LGC identification information and display regions in different blood flow signal width directions; adjusting association relations exist among different TGC gain adjusting instructions, different LGC gain adjusting instructions and blood flow gain;
s202, determining a first display area in the depth direction of the blood flow signal corresponding to the TGC identification information by using a first area incidence relation; determining a second display area in the width direction of the blood flow signal corresponding to the LGC identification information by using the second area association relation;
s203, taking the collection of the first display area and the second display area as an area to be regulated in the blood flow image;
and S204, adjusting the blood flow gain of the area to be adjusted according to the TGC gain adjusting instruction, the LGC gain adjusting instruction and the adjusting association relation.
It should be noted that, since most of the LGCs are displayed on the touch screen, and are only displayed in the two-dimensional mode, but not displayed in the blood flow mode, in this embodiment, in order to facilitate the user to adjust the blood flow gain, before acquiring the TGC gain adjustment information and the LGC gain adjustment information, the method further includes: judging whether the current ultrasonic mode is a blood flow mode or not; and if so, displaying an LGC adjusting control on the touch screen so as to generate LGC gain adjusting information through the LGC adjusting control.
That is, before generating the adjustment information, it may be automatically checked whether the current ultrasound mode is a blood flow mode, and if the current ultrasound mode is the blood flow mode, the LGC adjustment control is displayed on the touch screen; the LGC adjusting control is an LGC slider adjusting button comprising an LGC slider, and by the mode, the LGC adjusting control can be automatically displayed in a blood flow mode, so that the convenience of a user for using the LGC adjusting control is improved; of course, if the LGC slider adjustment button itself is set on the control panel, the function of automatically displaying the corresponding LGC adjustment control may be turned off according to the user's setting in advance.
It can be understood that, according to the scheme, the first area association relationship and the second area association relationship are preset, that is: associating different TGC identification information with display areas in different blood flow signal depth directions one by one in advance, and associating different LGC identification information with display areas in different blood flow signal width directions one by one; therefore, after the TGC identification information and the LGC identification information are obtained, the first display area in the depth direction of the blood flow signal corresponding to the TGC identification information can be determined according to the association relationship between different TGC identification information and display areas in different depth directions of the blood flow signal; and determining a second display area in the width direction of the blood flow signal corresponding to the LGC identification information according to the incidence relation between the different LGC identification information and the display areas in the width directions of the different blood flow signals, and taking the collection of the first display area and the second display area as an area to be regulated in the blood flow image.
