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 hypermetabolic region parameter information generation method according to a first embodiment of the present invention, and the method according to the first embodiment of the present invention is suitable for a case of hypermetabolic region parameter information generation in a PET medical image. May be performed by a hypermetabolic region parameter information generating apparatus, wherein the apparatus may be implemented by software and/or hardware. As shown in fig. 1, the hypermetabolic region parameter information generating method includes:
and S110, acquiring a target medical image.
Illustratively, a first medical image is acquired, and the first medical image is taken as a target medical image, that is, the acquired first medical image is taken as the target medical image directly. However, considering that the medical image may now be a multi-modal image, acquiring the target medical image may further comprise: the method comprises the steps of acquiring a first medical image, determining a second medical image corresponding to the first medical image according to the first medical image, and taking the second medical image as a target medical image.
S120, receiving a first operation on a target area in target medical image data, determining a first cross section of the target area corresponding to the first operation according to the first operation, and generating and displaying parameter information of the first cross section in a first preset area.
Alternatively, the first operation may be a mouse click operation, a mouse hover operation, or the like. For example, when the first cross section information in the target area needs to be viewed, the selection of a certain cross section in the target area can be realized through a point selection operation. Specifically, the selection operation may be received by an external device. For example, when a user performs a click operation with a mouse, movement of the mouse and the click operation may be received. Illustratively, the point selecting operation may include: a left click operation of the user on a target point in the target area, or a right click operation of the user on a target point in the target area, or the like. The clicking operation comprises a single clicking operation or a double clicking operation and the like.
In medical images, it is often necessary to confirm parameter information, such as the size of the target region, in order to determine the medical information characterized by the target image with reference to the parameter information. In this embodiment, the related information of the target region in the target medical image may be represented by a first cross section of the target region, the first cross section of the target region corresponding to the first operation is determined according to the first operation, and the parameter information of the first cross section is generated and displayed in a first preset region. For example, the information related to the first cross section corresponding to the first operation may be calculated through the external contour coordinate parameter of the target region, and the parameter information such as the cross-sectional area of the first cross section may be generated. Wherein, the parameter information comprises an SUV value, a cross section area, a major axis, a minor axis or the like.
Wherein the target region includes a hypermetabolic region in the target medical image, and the like. Specifically, generating and displaying the parameter information of the first cross section in the first preset area may include: determining a maximum cross-section of the hypermetabolic region; generating major and minor axis information of the maximum cross-section and displaying the major and minor axes of the maximum cross-section in the hypermetabolic region.
And S130, when a second operation is received within a preset time, continuously displaying the parameter information in a second preset area of the target medical image according to a preset format.
Considering that the user may need to retain the parameter information, whether the second operation is received may be detected within a preset time period after the parameter information of the first cross section is displayed in the first preset area. Wherein the second operation is used for indicating that the parameter information is continuously displayed in a second preset area of the target medical image according to a preset format. It is understood that the preset time can be set according to actual requirements, such as 5 seconds, 10 seconds, 15 seconds, and the like, and is not limited herein. The method has the advantages that whether the parameter information needs to be continuously displayed or not can be considered for a certain time, so that the method can keep effective information and avoid the condition that information without reference value is kept and the storage space is occupied. It should be noted that the first preset area and the second preset area may be the same or different. For example, the first preset area may be an adjacent area in or close to a target area triggered by the first operation; the second region may be a region that does not affect the user's view of various tissue structures in the medical image, such as a peripheral region of the image.
Similarly, the first operation and the second operation may or may not be the same. Illustratively, the first operation may be a mouse-over operation; the second operation may be a shortcut key preset in the keypad.
According to the technical scheme of the embodiment of the invention, after the target medical image is obtained, the parameter information of the first cross section corresponding to the first operation can be generated and displayed through the first operation on the target area in the target medical image data, namely the parameter information can be automatically generated for the user to refer; when the second operation is received, the parameter information is continuously displayed, the personalized requirements of the user can be met, misoperation is effectively prevented, unnecessary repeated operation is avoided, the operation is simple and convenient, the time is saved, and the working efficiency of the user is improved.
On the basis of the above technical solution, the method for displaying the parameter of the image according to the embodiment of the present invention may further include: and receiving selection operation of each parameter information in the statistical table, and displaying a first cross section corresponding to the parameter information and the parameter information in the target medical image.
Usually, a doctor stores the parameter information of the cross section of the high metabolic region in the above steps, and specifically, statistically stores the parameter information of the cross section and the cross section according to the corresponding relationship, so that after the parameter information of the cross section stored in the statistical table is selected, the first cross section corresponding to the parameter information can be determined according to the corresponding relationship, and the first cross section and the parameter information corresponding to the first cross section are displayed in the target medical image. Illustratively, when receiving that a user can select any parameter information in a statistical table stored with cross section parameters by means of mouse click or other triggering methods, displaying the selected target first cross section and the parameter information in the target medical image.
By adopting the technical scheme, the first cross section corresponding to the parameter information and the parameter information can be displayed in the target medical image by receiving the selection operation of each parameter information in the statistical table, namely, the user can display the corresponding cross section by selecting the parameter information in the subsequent process, so that the cross section parameter information can be quickly called and managed when the user uses the cross section in the subsequent process, the query is quick and convenient, the process of repeatedly generating the parameter information is not needed, the time is saved, and the response efficiency is improved.
Example two
Fig. 2 is a flowchart of a hypermetabolic region parameter information generating method in the second embodiment of the present invention. The embodiment of the present invention is optimized based on the first embodiment, specifically, the receiving of the first operation on the target region in the first medical image data is optimized to be corresponding to the receiving of the hovering operation on the hypermetabolic region in the first medical image data, and the determining of the first cross section of the target region corresponding to the first operation according to the first operation is optimized to be: and determining a first cross section of a hypermetabolic region corresponding to the hovering operation according to the hovering operation.
On the basis, the parameter information of the first cross section is further generated and displayed in a first preset area and optimized to determine the maximum cross section of the hypermetabolic area; generating major and minor axis information of the maximum cross-section and displaying the major and minor axes of the maximum cross-section in the hypermetabolic region.
As shown in fig. 2, the medical image parameter display method in this embodiment may specifically include:
and S210, acquiring a target medical image.
S220, receiving a hovering operation on a high metabolism area in first medical image data, and determining a first cross section of the high metabolism area corresponding to the hovering operation according to the hovering operation.
In general, there are usually a variety of corresponding treatments for regions of high metabolism due to the need to acquire them, for example: segmentation, extraction, and delineation, etc. Each process corresponds to an operation. Therefore, the hovering operation can be taken as the operation of selecting the cross section. On the one hand, it can be distinguished from other functional operations. In addition, since the operation of selecting a cross section is used more frequently than other functional processes, the hovering operation is more convenient than other operations. Therefore, the hovering operation can be taken as the operation of selecting the cross section.
S230, determining the maximum cross section of the hypermetabolic region, generating the long axis and short axis information of the maximum cross section, and displaying the long axis and short axis of the maximum cross section in the hypermetabolic region.
In medical images, the information of the maximum cross section is an important reference information. It can be used to characterize the largest features of the hypermetabolic region in general. The length of the major axis and the minor axis of the cross section is usually used to characterize the size of the hypermetabolic region, so as to measure the severity of the disease. Since the point selection operation performed by the doctor is visually and empirically, it is easy to consider other cross sections as the maximum cross section, and thus erroneous maximum cross section information is acquired. In this embodiment, the maximum cross-section can be determined by calculating the areas of all cross-sections constituting the three-dimensional structure of the hypermetabolic region and by comparison. Generating the maximum cross-section and displaying said maximum cross-section in a three-dimensional image of said hypermetabolic region. To prompt the physician with information and the location of the maximum cross-section. Avoid the doctor to generate the selection error of the maximum cross section.
In this embodiment, the long axis and short axis information of the cross-section can be generated according to the point selection operation of the doctor. Illustratively, the long axis information and the short axis information of the corresponding cross section can be acquired by selecting the cross section, and the acquired long axis information and the acquired short axis information are marked and displayed on the corresponding cross section. For example: the point selection operation is a hovering operation, when the mouse hovers over the cross section of the current high metabolic region, long axis and short axis information can be generated according to edge coordinate information of the cross section, the long axis and the short axis of the current cross section can be drawn in the current cross section region, and corresponding marks are adopted for highlighting, such as solid lines or dotted lines.
For example, when any cross section is selected, information of the maximum cross section and the major and minor axes may be displayed while generating and displaying information of the selected cross section and the major and minor axes. If the long axis and the short axis drawn on the current cross section are the maximum long axis and the maximum short axis of the hypermetabolic region, the long axis and the short axis drawn on the current cross section are displayed by solid lines; if the current cross-section is not the maximum cross-section, the major and minor axes of the current cross-section plot are shown in dashed lines and the maximum cross-section and major and minor axes are shown in solid lines. In this way, the physician may be prompted that the currently selected cross-section is not the largest cross-section of the hypermetabolic region. In addition, the user can further turn the cross section up and down through the turning operation until the cross section is turned to the maximum cross section, and the long axis and the short axis of the dotted line can be drawn as solid lines, so that the current cross section can be prompted to the doctor to be the maximum cross section of the hypermetabolic region. The layer-turning operation may be a scrolling operation of a mouse wheel, or the like.
Since the extracted hypermetabolic region may be an irregular three-dimensional model, the selected first cross section may be an irregular figure, which is very inconvenient and prone to measurement inaccuracy when performing measurement calculation. In order to overcome the above disadvantages, in this embodiment, the irregular first cross section may be approximately outlined into an elliptical figure similar to the first cross section, so that when measuring and labeling the major axis and the minor axis, the major axis and the minor axis may be conveniently and accurately marked in the elliptical figure, and information of the major axis and the minor axis may be output. For example, a first cross section may be outlined first, and at least 6 points may be selected from the first cross section for an analysis of the connected region, and an elliptical shape may be outlined by a least-squares fit. Because a plurality of ellipses can be outlined by adopting a minimum quadratic fitting mode, the ellipses which are not in accordance with the actual situation need to be eliminated. For example, the ratio of the major axis to the minor axis of all ellipses may be calculated, ellipses larger than a preset threshold value of the ratio of the major axis to the minor axis may be eliminated, ellipses smaller than a preset threshold value of the ratio of the major axis to the minor axis may be retained, the threshold value of the ratio of the major axis to the minor axis may be empirically obtained, and the threshold value of the ratio of the major axis to the minor axis may be set in plural numbers with different heights. The information of the transverse axis and the short axis is calculated according to the retained ellipse. Namely, an approximate elliptical figure can be drawn according to the first cross section, and the information of the major axis and the minor axis of the elliptical figure can be generated.
And S240, when a second operation is received within a preset time, continuously displaying the parameter information in a second preset area of the target medical image according to a preset format.
According to the technical scheme in the embodiment, the target area is specifically a high metabolic area, a focus high-incidence area can be more quickly positioned as a key area by combining medical experience, unnecessary area selection can be saved, time is saved, and efficiency is improved; secondly, by means of the maximum cross section of the hypermetabolic region and displaying the information of the long axis and the short axis in the maximum cross section, the size of the target region can be effectively represented, and an effective basis is provided for auxiliary diagnosis.
On the basis of the embodiment of the present invention, the method may further include: and storing the parameter information into a statistical table. Specifically, the parameter information and the first cross section information may be correspondingly stored in a statistical table according to the corresponding relationship between the parameter information and the first cross section; or correspondingly storing the parameter information and the first cross section information into a statistical table according to the corresponding relation among the parameter information, the first cross section and the target area; or, correspondingly storing the parameter information and the first cross section information into a statistical table according to the corresponding relation among the parameter information, the first cross section, the target region and the target medical image.
After generating the first cross section of the target region and the parameter information corresponding to the first cross section, a dialog box may pop up to display the parameter information of the generated cross section near the image. The doctor can conveniently obtain the parameter information. Physicians often use manual records of parameter information for later diagnostic use via manually recorded data. Since the doctor needs to record information of a plurality of first cross sections for diagnosis, the amount of work is large. In order to save the workload of the doctor, the doctor can generate a storage instruction through a set storage operation, for example, by clicking a storage button arranged in the interface, and the system stores the generated parameter information of the first cross section by receiving the storage instruction, so as to perform diagnosis and use through manually recorded data at a later stage. Or, when the doctor uses the hovering to outline the first cross section of the target area, if the doctor wants to keep the parameter information of the current first cross section, the doctor can save the parameter information of the current first cross section by receiving a storage instruction. For example, a keyboard shortcut key is pressed to store the currently hovering first cross section parameter information and the corresponding target area profile, and the first cross section parameter information and the corresponding target area profile are stored in a statistical table form. Preferably, the parameter information of the first cross section can be stored in a quaternary statistical table in a table mode, so that a doctor can conveniently search the quaternary statistical table. The doctor can export the information in the statistics sheet, create a management archive and print the statistics sheet into a paper file for convenient viewing and collating.
The technical scheme can be particularly suitable for the condition that a user needs to record the parameter information, and can be particularly suitable for the condition that the user needs to record the parameter information corresponding to a plurality of target areas simultaneously, so that the parameter information can be effectively managed, and convenience is provided for follow-up inquiry.
