Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a medical image viewing method according to an embodiment of the present invention, which is applicable to a case of viewing a two-dimensional medical image or a three-dimensional medical image. The method may be performed by a medical image viewing device integrated in the cloud, which may be implemented in software and/or hardware. As shown in fig. 1, the method specifically includes the following steps:
and S110, receiving an image viewing request sent by a user side.
The user terminal may refer to a device terminal at which a user views a medical image. For example, the user side may refer to, but is not limited to, a web page side or an application client side. The web page end can be a browser of a hospital doctor workstation, and the application client can be a mobile phone client of a patient.
The medical image may be a two-dimensional medical image or a three-dimensional medical image. For example, the medical images may include, but are not limited to: magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Computed Tomography (CT), cone beam CT, or three-dimensional ultrasound Imaging.
Specifically, when the user needs to view the medical image, an image viewing operation may be triggered at the user end, such as: clicking a viewing button for viewing the image to enable a user side to obtain an image identifier to be viewed based on image viewing operation triggered by a user, generating an image viewing request based on the image identifier to be viewed, and sending the image viewing request to a cloud side, so that the cloud side can receive the image viewing request.
S120, determining a target DICOM image file based on the image identification to be viewed in the image viewing request and each pre-stored DICOM image file.
The to-be-viewed image identifier may refer to a unique identifier corresponding to the DICOM image file, so as to distinguish the DICOM image files of different patients based on the identifier. The embodiment may use the patient information as the identifier of the image to be viewed, or may use the unique serial number generated when the medical image is acquired as the identifier of the image to be viewed.
Specifically, the cloud may store DICOM image files of various patients in advance. For example, medical images of a patient are acquired with an imaging device, such as a CT device. The medical images of the collected patients can be converted into a DICOM format by using a PACS (Picture Archiving and Communication Systems), a DICOM image file is generated, and the DICOM image files of the patients can be transmitted to the cloud in batch, so that the cloud stores the received DICOM image files of the patients, and the client can call the DICOM image files at any time. The cloud end can analyze the image viewing request after receiving the image viewing request, obtain an image identifier to be viewed, match the image identifier corresponding to each pre-stored DICOM image file with the image identifier to be viewed, and determine a target DICOM image file corresponding to the image identifier to be viewed.
S130, cloud analysis is carried out on the target DICOM image file, and a target image sequence corresponding to a preset image format is obtained.
The preset image format may refer to a general image viewing format, so that image viewing can be performed using general application software. For example, the preset image format may be, but is not limited to, a jpg format, i.e., a format in which the image file is compressed to a minimum in order to further reduce the amount of data transmission. The target image sequence may include one or more target images. The target image sequence may be one or more. For example, during a single CT examination, 900 image files in DICOM format can be generated, and each image is classified into different image sequences according to different angles or positions, so as to generate a plurality of image sequences.
Specifically, the cloud may perform file parsing on all target DICOM image files to be viewed, convert the DICOM format into a preset image format, and obtain a target image sequence that can be directly displayed on the user side. File analysis efficiency can be improved by utilizing stronger equipment performance of the cloud end to analyze files.
S140, determining a target area image sequence based on the target image sequence and preset viewing area information, and sending the target area image sequence to a user side so that the user side can display the target area image sequence.
The preset viewing area information may be preset, and the information of the effective viewing area is defaulted when the user views the information for the first time. The effective viewing area may refer to an image viewable area when a user views an image at a user end. For example, the preset viewing area information may include, but is not limited to: and anchor point position information, width information, height information and image rotation angle information corresponding to the default image viewing area during first viewing. The anchor point position information may refer to position information of an upper left corner of the image viewing area.
Specifically, the cloud terminal can select a target area image corresponding to a preset viewing area from each target image in the target image sequence based on the preset viewing area information, obtain a target area image sequence with a smaller data volume, and send the target area image sequence to the user terminal, so that the cloud terminal only needs to send the target area image sequence corresponding to the effective viewing area, and does not need to send a whole target DICOM image file, thereby realizing the regional transmission of the images, greatly reducing the data transmission volume, enabling the user to quickly view the target area image sequence corresponding to the effective viewing area, improving the viewing speed of the medical images, reducing the user waiting time, enabling the user to view the image data in the largest area under the same bandwidth, and further improving the user viewing experience.
For example, after receiving the target area image sequence, the user terminal may automatically play each target area image in the target area image sequence in the display interface, or may display the target area images in the target area image sequence one by one based on a user operation.
Exemplarily, the "determining the target region image sequence based on the target image sequence and the preset viewing region information" in S140 may include: acquiring the display resolution of a user side in an image viewing request; and determining the target area image sequence based on the target image sequence, the preset viewing area information and the display resolution.
The display resolution of the user terminal may refer to a maximum resolution supported by a display screen of the user terminal.
Specifically, when the user terminal generates the image viewing request based on the image viewing operation triggered by the user, the image viewing request may be generated based on the identifier of the image to be viewed and the display resolution of the user terminal, so that the cloud terminal may obtain the display resolution of the user terminal by analyzing the image viewing request. The cloud end can be based on preset viewing area information and display resolution, each target image in the target image sequence is processed, the target area image sequence matched with the display resolution is obtained, for example, the image resolution of the target area image is equal to the display resolution of the user end, so that the generation of the area image with overlarge or undersize resolution can be avoided, the sub-resolution transmission of the image is realized, the situation that the user can view the clearest area image is guaranteed, and the user viewing experience is further improved.
In the technical scheme of the embodiment, the cloud end determines the target DICOM image file by receiving the image viewing request sent by the user end, based on the image identifier to be viewed in the image viewing request and each pre-stored DICOM image file, performs cloud end analysis on the target DICOM image file to obtain the target image sequence corresponding to the preset image format, determines the target area image sequence based on the target image sequence and the preset viewing area information, and sends the target area image sequence to the user end, so that the user end can directly display the target area image sequence, the cloud end only needs to send the target area image sequence corresponding to the effective viewing area obtained after analysis, the whole target DICOM image file does not need to be sent, the image transmission in different areas is realized, the data transmission amount is greatly reduced, and a user can quickly view the target area image sequence corresponding to the effective viewing area, therefore, the medical image viewing speed is improved, the user waiting time is reduced, and the user viewing experience is improved.
On the basis of the above technical solution, S140 may include: if the number of the images corresponding to the target image sequence is less than or equal to the preset number, the target image sequence is sent to the user side, so that the user side determines the target area image sequence based on the target image sequence and the preset viewing area information, and displays the target area image sequence; and if the number of the images corresponding to the target image sequence is greater than the preset number, determining the target area image sequence based on the target image sequence and the preset viewing area information, and sending the target area image sequence to the user side so that the user side can display the target area image sequence.
The preset number can be preset, and the number of images of the whole image can be directly transmitted. For example, the preset number may be set to 1. Specifically, when the number of images contained in the target image sequence is small, the cloud directly sends the whole target image sequence to the user side without affecting viewing efficiency, so that the user side determines the target area image sequence based on the received target image sequence and preset viewing area information, and displays the target area image sequence corresponding to the effective viewing area, so that dynamic change of the viewing area can be directly performed in the user side in the subsequent process, the target area image sequence does not need to be sent to the cloud again for changing the viewing area, and the viewing efficiency is further improved. When the number of images contained in the target image sequence is large, the target area image sequence with small data volume is determined in the cloud, and the target area image sequence is sent to the user side, so that the image viewing speed is further guaranteed.
Illustratively, when the target DICOM image file is a single-layer image file, the target DICOM image file may be directly sent to the user side, so that the user side locally parses the received target DICOM image file to obtain a target image sequence corresponding to a preset image format, and determines and displays the target area image sequence based on the target image sequence and preset viewing area information. When the target DICOM image file is a multilayer image file, cloud analysis can be performed on the target DICOM image file to obtain a target image sequence corresponding to a preset image format; and determining a target area image sequence based on the target image sequence and preset viewing area information, and sending the target area image sequence to the user side so that the user side can display the target area image sequence. Through the self-adaptive processing mode combining the local analysis and the cloud analysis, the viewing speed of the medical image can be further improved, and the viewing experience of a user is improved.
On the basis of the above technical solutions, the method may further include: determining a thumbnail corresponding to the target area image sequence; and sending the thumbnail to the user side so that the user side can carry out related display on the thumbnail and the target area image sequence.
The thumbnail may refer to a representative image corresponding to the target area image sequence, so that information such as an acquisition angle or an acquisition position corresponding to the corresponding target area image sequence can be quickly obtained based on the thumbnail. The resolution of the thumbnail may be less than the resolution of the target area images in the target area image sequence to further reduce the data transmission amount and increase the transmission speed while ensuring that the user can see clearly.
Specifically, one target area image may be randomly selected from the target area image sequence as a corresponding thumbnail, or the first target area image in the target area image sequence may be used as a corresponding thumbnail. And the resolution ratio of the selected target area image can be adjusted, and the thumbnail with lower resolution ratio can be determined. The cloud end sends the determined thumbnail corresponding to the target area image sequence to the user side, and the user side can perform associated display on the target area image sequence and the corresponding thumbnail so as to further improve the viewing experience of the user. For example, the user terminal may display the received thumbnail in a left area of the display interface, and may display a corresponding target area image sequence in a right area of the display interface when a user click operation on the thumbnail is detected. If a plurality of target area image sequences exist, the user side can display corresponding thumbnails in a list mode, and can display the target area image sequences corresponding to the thumbnails when the user clicks a certain thumbnail, so that the user can more quickly view the images which the user wants to view, and the user viewing experience is further improved.
Example two

S220, determining a target DICOM image file based on the image identification to be viewed in the image viewing request and each pre-stored DICOM image file.
And S230, carrying out cloud analysis on the target DICOM image file to obtain a target image sequence corresponding to the preset image format.

And S250, receiving a viewing area change request sent by a user side, wherein the viewing area change request is generated based on a viewing area change operation triggered by the user aiming at the currently displayed area image sequence.
Specifically, when a user wants to view images of other areas after viewing a target area image sequence corresponding to a preset viewing area, a viewing area changing operation may be triggered in a preset manner, for example, the user may move a displayed area image to change the viewing area in a gesture or a mouse or other manners. The user side can determine viewing area change information corresponding to an image viewing area currently selected by a user based on the moving position information of the displayed area image, generates a corresponding viewing area change request based on the viewing area change information, and sends the viewing area change request to the cloud side, so that the cloud side requests to transmit area image sequences corresponding to other viewing areas based on the viewing area change.
And S260, determining a current area image sequence to be viewed currently based on the target image sequence and the viewing area change information in the viewing area change request, and sending the current area image sequence to the user side so that the user side can display the current area image sequence.
Wherein, the viewing area change information may include but is not limited to: anchor point position information, width information, height information and image rotation angle information corresponding to the image viewing area currently selected by the user.
Specifically, the cloud end can analyze the received viewing area change request to obtain viewing area change information corresponding to the image viewing area currently selected by the user, select the current area image corresponding to the changed viewing area from each target image in the target image sequence based on the viewing area change information to obtain the current area image sequence, and send the current area image sequence to the user end, so that the user can rapidly view the image content of other areas on the user end, thereby realizing image dynamic update and regional transmission of the user visual area, ensuring the viewing speed of the medical image, and improving the viewing experience of the user.
According to the technical scheme, the cloud end determines the current area image sequence to be viewed currently by receiving the viewing area change request sent by the user end, based on the target image sequence and the viewing area change information in the viewing area change request, and sends the current area image sequence to the user end, so that the user end displays the current area image sequence, dynamic image updating and regional transmission of the user visual area are achieved, the viewing speed of medical images is guaranteed, and the viewing experience of the user is improved.
