[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the method for adjusting the window width and window level of a medical image includes step 100, step 101 and step 102.

[0026] The medical image window width and window level adjustment method provided in the embodiment of the present invention may be executed by an electronic device or software or a functional module or a functional entity in the electronic device that can implement the medical image window width and window level adjustment method. In the embodiment of the present invention, the electronic device includes but is not limited to a film reading device. It should be noted that the above-mentioned execution subject does not constitute a limitation to the present invention.

[0027] Step 100: Obtain device type and scanning part information of a target medical image, and determine a target group corresponding to the target medical image based on the device type and scanning part information.

[0028] The target medical image may be a Digital Imaging and Communications in Medicine (DICOM) image.

[0029] The electronic device can read information corresponding to the target medical image from the target medical image, such as patient number, scanned part, device type, device name, device manufacturer, current window width and window position, etc.

[0030] The device type and scanning part information of the target medical image are obtained, and the target group corresponding to the target medical image is determined according to the device type and scanning part information of the target medical image.

[0031] Medical images with the same device type and the same scanning part information can be classified into the same group.

[0032] Step 101: Determine window width and window level adjustment information corresponding to the target group.

[0033] It should be noted that the window width and window level adjustment information corresponding to the target group may be obtained by analyzing the operation data of multiple medical images in the target group.

[0034] By analyzing the operation data of multiple medical images in the target group, the operator's operation information on the medical images in the target group can be determined, and the operation information may include at least one of the following: the accumulated average value of window width adjustment, the accumulated maximum value of window width adjustment, the accumulated minimum value of window width adjustment, the accumulated average value of window level adjustment, the accumulated maximum value of window level adjustment, and the accumulated minimum value of window level adjustment.

[0035] Based on the operation information, the window width and window level adjustment information corresponding to the target group can be determined. The window width and window level adjustment information can include the step length of the window width and the step length of the window level, and can also include the initial value of the window width and the initial value of the window level.

[0036] Step 102: Adjust the window width and window level of the target medical image based on the window width and window level adjustment information corresponding to the target group.

[0037] Optionally, adjusting the window width and window level of the target medical image includes the following two cases.

[0038] 1. Adjust the step size of window width and window position.

[0039] The window width adjustment step length of the target medical image may be set to the minimum value or average value of the accumulated window width adjustment; the window level adjustment step length of the target medical image may be set to the minimum value or maximum value of the accumulated window level adjustment.

[0040] For example, the initial window width adjustment step is 20. After statistical analysis, the cumulative minimum value of the window width adjustment of the medical images in the target group is 100, the cumulative maximum value is 200, and the cumulative average value is 135. That is to say, the operator needs to make multiple adjustments to adjust the window width to an appropriate size.

[0041] The window width adjustment step of the target medical image can be set to the minimum value or average value of the accumulated window width adjustment, that is, the operator can be provided with whether to automatically change the window width adjustment step to 100 or 135. In other words, the operator can adjust the window width of the target medical image by 100 or 135 in one operation. After the operator makes one adjustment, the step length of the window position is restored to the default value of 20, and only fine-tuning is required afterwards, which improves the operator's efficiency in reading films.

[0042] 2. Adjust the initial value of the window width and the initial value of the window position.

[0043] The initial value of the window width and the initial value of the window level can be determined based on the window width and window level adjustment information, and the initial window width and initial window level of the target medical image can be automatically set. For example, after opening the image, the window width is automatically adjusted to 850 and the window level is automatically adjusted to 900.

[0044] The window width and window level adjustment method for medical images provided by the embodiment of the present invention determines the target group corresponding to the medical image by acquiring the device type and scanning part information of the medical image, adjusts the window width and window level of the medical image based on the window width and window level adjustment information corresponding to the target group, performs corresponding window width and window level adjustment for different groups, reduces the steps of the operator's operation, improves the speed of adjusting the window width and window level of the medical image, and improves the operator's film reading efficiency.

[0045] In some embodiments, the method for adjusting the window width and window position of a medical image further includes: obtaining window width and window position operation information of a plurality of medical images, and performing statistical analysis. Figure 2 As shown, obtaining window width and window position operation information of multiple medical images and performing statistical analysis includes: step 200, step 201, step 202 and step 203.

[0046] Step 200: Acquire information of a plurality of medical images, wherein the information of the medical images includes at least one of the following: device type, scanning part, patient number, device manufacturer, and current window width and window position.

[0047] When the operator opens the medical image, the electronic device automatically reads the patient number, scanning part, device type, device name, device manufacturer and current window width and window position from the medical image, compiles it into a group number or finds the corresponding group number, and compiles the serial number within the group.

[0048] For example: the patient number is 04011305, the scanning site is the lung, the device type is computed tomography (CT), the device name is CTNS09005, the device manufacturer is NS, the window width is 700, the window position is 600, the group number is LC101014, and the serial number within the group is 211216001.

[0049] Step 201: group the medical images based on the information corresponding to the medical images, and obtain the group number corresponding to the medical images and the serial number within the group number.

[0050] It should be noted that the purpose of grouping multiple medical images is to classify medical images with similar operating habits of operators into the same group, so as to facilitate statistical analysis of window width and window position operation information corresponding to each group and obtain window width and window position adjustment information corresponding to each group.

[0051] Optionally, since operators have similar operating habits for medical images with the same device type and scanning part, the medical images can be grouped according to the device type and scanning part information corresponding to each medical image, and the medical images with the same device type and scanning part information can be grouped into the same group. For example, CT medical images of the lungs correspond to one group, and CT medical images of the brain correspond to another group.

[0052] The intra-group serial number of each medical image within the group number may be determined according to the patient number corresponding to each medical image.

[0053] Step 202: Obtain window width and window level operation information corresponding to each of the medical images, and record the window width and window level operation information into a data sequence represented by a sequence number corresponding to each of the medical images.

[0054] It is understandable that the window width and window position operation information corresponding to each medical image may include multiple operation information, so the multiple operation information is recorded in the form of a data sequence to obtain a data sequence represented by a sequence number corresponding to each medical image.

[0055] In some embodiments, the window width and window level operation information corresponding to each of the medical images includes at least one step of window width and window level operation information.

[0056] In some embodiments, Figure 3 As shown, step 202 includes: step 300, step 301 and step 302.

[0057] Step 300: Receive a first input, where the first input is an operation of adjusting the window width or window level of the medical image at least once.

[0058] It can be understood that the receiving operator adjusts the window width or window level of the medical image.

[0059] Step 301: When a second input is received, determine window width and window level operation information corresponding to a one-step operation based on the first input and the second input.

[0060] The second input is other operations except adjusting the window width or window level, for example, the operator starts to observe the medical image.

[0061] The one-step operation includes adjusting the window width or window level of the medical image at least once.

[0062] Adjusting the window width of the medical image once refers to adjusting the window width size once according to the window width adjustment step of the medical image, including positive adjustment and / or reverse adjustment. For example, the window width of the medical image is 500, and the window width adjustment step of the medical image is 20. Then adjusting the window width of the medical image once can adjust the window width of the medical image to 480 or 520.

[0063] Similarly, adjusting the window level of a medical image once means adjusting the window level size once according to the window level adjustment step of the medical image, including positive adjustment and / or reverse adjustment. For example, the window level of the medical image is 800, and the window level adjustment step of the medical image is 50. Then adjusting the window level of the medical image once can adjust the window level of the medical image to 750 or 850.

[0064] It is understandable that the operation can be divided into multiple steps according to the second input and the first input.

[0065] Optionally, each time a second input is received, it indicates that one operation is completed, and the first input between every two adjacent second inputs is one operation.

[0066] For example, the first input before the second input received for the first time is classified as the first step operation; the first input between the second input received for the first time and the second input received for the second time is classified as the second step operation, and so on, the window width and window position operation information corresponding to each step operation can be determined.

[0067] Step 302: Record the window width and window position operation information corresponding to at least one operation step by step into the data sequence represented by the serial number corresponding to each of the medical images, wherein the window width and window position operation information corresponding to one operation includes the number of window width adjustments, the step length of the window width, the number of window position adjustments and the step length of the window position.

[0068] It can be understood that the data sequence represented by the serial number corresponding to each medical image records at least one step of operation information, and each step of the operation may include one adjustment or multiple adjustments. Therefore, the number of adjustments of the window width in each step of the operation, the step size of each adjustment of the window width, and the number of adjustments of the window position in each step of the operation, and the step size of each adjustment of the window position can be obtained.

[0069] Step 203: When the number of data sequences recorded corresponding to at least one group number reaches a first threshold, statistical analysis is performed on the data sequences recorded corresponding to each group number in the at least one group number to obtain window width and window level adjustment information corresponding to each group represented by the at least one group number.

[0070] The size of the first threshold can be set according to specific circumstances and is not specifically limited here.

[0071] For example, the first threshold is 100, and multiple medical images correspond to 6 group numbers: 001, 002, 003, 004, 005 and 006. The number of data sequences corresponding to these 6 group numbers is 90, 95, 99, 120, 130 and 140 respectively. It can be determined that the data sequences corresponding to the three group numbers 004, 005 and 006 have reached the first threshold. Perform statistical analysis on the 120 data sequences corresponding to the group number 004 to obtain the window width and window position adjustment information corresponding to the group represented by the group number 004; perform statistical analysis on the 130 data sequences corresponding to the group number 005 to obtain the window width and window position adjustment information corresponding to the group represented by the group number 005; perform statistical analysis on the 140 data sequences corresponding to the group number 006 to obtain the window width and window position adjustment information corresponding to the group represented by the group number 006.

[0072] In some embodiments, the window width and window level adjustment information includes a window width adjustment recommended step length sequence and a window level adjustment recommended step length sequence.

[0073] In some embodiments, Figure 4 As shown, in step 203, statistical analysis is performed on the data sequences corresponding to the records of each group number in the at least one group number to obtain the window width and window level adjustment information corresponding to each group represented by the at least one group number, including: step 400, step 401 and step 402.

[0074] Step 400: For any data sequence of records corresponding to a group of numbers, based on the window width and window level operation information corresponding to each operation step, determine the window width adjustment cumulative value and the window level adjustment cumulative value corresponding to each operation step.

[0075] It can be understood that each group number corresponds to at least one medical image, each medical image corresponds to a serial number, and the data sequence represented by the serial number records at least one step of operation information of the medical image, that is, each group number corresponds to at least one data sequence.

[0076] For a data sequence of records corresponding to any group number, the accumulated value of window width adjustment and the accumulated value of window level adjustment corresponding to each step of operation in the data sequence are determined.

[0077] For example, group number 004 corresponds to 120 data sequences, of which the first data sequence corresponds to three-step operation information, and in the first step of the operation, 5 window width adjustments are performed, each with a step length of 40, and a total of 6 window level adjustments are performed, each with a step length of 20. It can be determined that the cumulative window width adjustment value corresponding to the first step of the operation of the first data sequence is 200, and the cumulative window width adjustment value is 120. By analogy, the cumulative window width adjustment value and the cumulative window level adjustment value corresponding to each step of the operation in each data sequence corresponding to any group number can be determined.

[0078] Step 401: Based on the accumulated value of window width adjustment and the accumulated value of window level adjustment corresponding to each step of operation, determine the recommended step length of window width adjustment and the recommended step length of window level adjustment corresponding to each step of operation.

[0079] Optionally, the average value, maximum value and minimum value of the accumulated values ​​of the window width adjustment of the same synchronous operation corresponding to any group number can be calculated, and then the recommended window width adjustment step length corresponding to the step operation can be determined according to the average value, maximum value and minimum value.

[0080] For example, the accumulated window width adjustment values ​​corresponding to the 120 first-step operations can be determined from the 120 data sequences corresponding to the group number 004, so that the average value of the accumulated window width adjustment values ​​of the first-step operation is determined to be 135, the minimum value is 100, and the maximum value is 200, that is, the recommended step length of the window width adjustment for the first-step operation of the group number 004 is 100 or 135; the accumulated window level adjustment values ​​corresponding to the 120 first-step operations can be determined from the 120 data sequences corresponding to the group number 004, so that the average value of the accumulated window level adjustment values ​​of the first-step operation is determined to be 250, the minimum value is 200, and the maximum value is 400, so the recommended step length of the window level adjustment for the first-step operation of the group number 004 can be determined to be 200 or 400.

[0081] Step 402: Based on the recommended window width adjustment step length and the recommended window level adjustment step length corresponding to each operation step, determine the recommended window width adjustment step length sequence and the recommended window level adjustment step length sequence corresponding to each group represented by the at least one group number.

[0082] It is understandable that the medical images in each group may correspond to multiple operations, and each operation step may correspond to a recommended step length for window width adjustment and a recommended step length for window level adjustment.

[0083] Therefore, a window width adjustment recommended step length sequence corresponding to a group includes a window width adjustment recommended step length corresponding to each operation step, and a window level adjustment recommended step length sequence corresponding to a group includes a window level adjustment recommended step length corresponding to each operation step.

[0084] The window width and window level adjustment method for medical images provided by an embodiment of the present invention groups multiple medical images, obtains a data sequence according to operation information of the medical images, and performs statistical analysis on the data sequence recorded corresponding to the group number when the data sequence recorded corresponding to the group number reaches a first threshold value, obtains window width and window level adjustment information corresponding to the group represented by the group number, and uses the window width and window level adjustment information to adjust the window width and window level of the corresponding group, thereby improving the speed of adjusting the window width and window level and improving the operator's film reading efficiency.

[0085] In some embodiments, step 101 includes:

[0086] The recommended window width adjustment step sequence and the recommended window level adjustment step sequence corresponding to the target group are determined from the recommended window width adjustment step sequences and the recommended window level adjustment step sequences corresponding to the respective groups represented by the at least one group number.

[0087] Optionally, at least one group number includes a group number corresponding to a target medical image, that is, the number of data sequences recorded corresponding to the group number corresponding to the target medical image has reached a first threshold, and window width and window level adjustment information corresponding to a target group corresponding to the target medical image is obtained through statistical analysis. The window width and window level adjustment information corresponding to the target group includes a window width adjustment recommended step length sequence and a window level adjustment recommended step length sequence corresponding to the target group.

[0088] The window width and window level adjustment method for medical images provided by an embodiment of the present invention groups multiple medical images, obtains a data sequence according to operation information of the medical images, and performs statistical analysis on the data sequence recorded corresponding to the group number when the data sequence recorded corresponding to the group number reaches a first threshold value, obtains window width and window level adjustment information corresponding to the group represented by the group number, and uses the window width and window level adjustment information to adjust the window width and window level of the corresponding group, thereby improving the speed of adjusting the window width and window level and improving the operator's film reading efficiency.

[0089] In some embodiments, Figure 5 As shown, step 102 includes: step 500, step 501, step 502 and step 503.

[0090] Step 500: For a target step operation, determine a target window width adjustment step of a target medical image corresponding to the target step operation from a recommended window width adjustment step sequence corresponding to the target group, and determine a target window level adjustment step of a target medical image corresponding to the target step operation from a recommended window level adjustment step sequence corresponding to the target group.

[0091] It should be noted that the target step operation may be any operation performed on the target medical image, and the target window width adjustment step length and the target window level adjustment step length corresponding to the target step operation may be determined by the received second input of the target medical image.

[0092] For example, when the second input of the operator is not received, it is determined that the current operation is the first step of the target medical image. The window width adjustment step length corresponding to the first operation is determined from the window width adjustment recommended step length sequence corresponding to the target group as the target window width adjustment step length of the target medical image; the window level adjustment step length corresponding to the first operation is determined from the window level adjustment recommended step length sequence corresponding to the target group as the target window level adjustment step length of the target medical image.

[0093] When a second input from the operator is received, it is determined that the current step is the second step, and by analogy, the target window width adjustment step length and the target window level adjustment step length corresponding to each step operation of the target medical image can be determined.

[0094] Step 501: Generate prompt information based on the target window width adjustment step and the target window level adjustment step, and display the prompt information through a prompt interface.

[0095] It is understandable that the prompt information on the display interface can provide the operator with the option of whether to adjust the current window width adjustment step to the target window width adjustment step and whether to adjust the current window level adjustment step to the target window level adjustment step.

[0096] For example, when the target window width adjustment step length is determined to be 100 and the target window level adjustment step length is determined to be 200, a prompt message is generated: Do you want to set the window width adjustment step length to 100? Do you want to set the window level adjustment step length to 200?

[0097] Step 502: When the third input is received, the window width adjustment step length of the target medical image is set to the target window width adjustment step length, and the window level adjustment step length of the target medical image is set to the target window level adjustment step length.

[0098] The third input may be in at least one of the following ways:

[0099] First, the third input may be a touch operation, including but not limited to a click operation, a slide operation, and a press operation.

[0100] In this implementation, receiving the third input from the operator may be receiving a touch operation from the operator in the display area of ​​the display screen.

[0101] Secondly, the third input may be a physical key input.

[0102] In this embodiment, a physical key corresponding to the step size setting is provided on the body of the electronic device, and receiving the third input from the operator may be receiving the third input from the operator by pressing the corresponding physical key.

[0103] Of course, in other embodiments, the third input may also be in other forms, including but not limited to voice input, etc., which can be determined according to actual needs and is not limited to this in the embodiments of the present application.

[0104] When the third input is received, the window width adjustment step length of the target medical image is set as the target window width adjustment step length, and the window level adjustment step length of the target medical image is set as the target window level adjustment step length.

[0105] Step 503: When the fourth input is received, the window width or window level of the target medical image is adjusted according to the target window width adjustment step length or the target window level adjustment step length.

[0106] The fourth input is an operation for determining to adjust the window width or window level of the target medical image. It is understandable that the fourth input is an operation for confirming the adjustment, but does not indicate the step length of the adjustment, which is determined according to the window width adjustment step length and the window level adjustment step length of the target medical image set in step 502, that is, when the fourth input is received, the window width or window level of the target medical image is adjusted according to the target window width adjustment step length and the target window level adjustment step length.

[0107] It should be noted that after the operator makes an adjustment, the step size of the window position returns to the default value, and only fine-tuning is required thereafter.

[0108] The method for adjusting the window width and window level of a medical image provided by an embodiment of the present invention determines the target window width adjustment step of a target medical image corresponding to the target step operation from a window width adjustment recommended step sequence corresponding to a target group, determines the target window level adjustment step of the target medical image corresponding to the target step operation from a window level adjustment recommended step sequence corresponding to the target group, and adjusts the window width and window level for each step operation, thereby improving the accuracy of setting the window width adjustment step and window level adjustment step of the medical image, improving the speed of adjusting the window width and window level, and improving the operator's film reading efficiency.

[0109] The window width and window level adjustment device for medical images provided by the present invention is described below. The window width and window level adjustment device for medical images described below and the window width and window level adjustment method for medical images described above can be referred to each other.

[0110] like Figure 6 As shown, the medical image window width and window level adjustment device 600 includes: an acquisition module 610 , an information determination module 620 and an adjustment module 630 .

[0111] An acquisition module 610 is used to acquire the device type and scanning part information of the target medical image, and determine the target group corresponding to the target medical image based on the device type and scanning part information;

[0112] An information determination module 620 is used to determine the window width and window level adjustment information corresponding to the target group;

[0113] The adjustment module 630 is used to adjust the window width and window level of the target medical image based on the window width and window level adjustment information corresponding to the target group.

[0114] Optionally, the medical image window width and window level adjustment device 600 further includes a statistical analysis module for:

[0115] Acquire information of a plurality of medical images, wherein the information of the medical images includes at least one of the following: device type, scanning site, patient number, device manufacturer, and current window width and window position;

[0116] Based on the information corresponding to each of the medical images, each of the medical images is grouped to obtain a group number corresponding to each of the medical images and a sequence number within the group number;

[0117] Acquire window width and window position operation information corresponding to each of the medical images, and record the window width and window position operation information into a data sequence represented by a sequence number corresponding to each of the medical images;

[0118] When the number of data sequences recorded corresponding to at least one group number reaches a first threshold, statistical analysis is performed on the data sequences recorded corresponding to each group number in the at least one group number to obtain window width and window level adjustment information corresponding to each group represented by the at least one group number.
