Description

Technical Field

[0001] The embodiments of the present invention relate to medical image processing technology, and in particular to a triggering method, device, equipment and storage medium for a region of interest. Background Art

[0002] In the post-processing of medical images, doctors observe the images of patients scanned by imaging equipment to make a diagnosis. When examining the images, it is necessary to manually mark the main anatomical structures and suspected lesions in the images or to correct the markings / algorithm recognition results for further observation and processing.

[0003] After drawing the region of interest such as suspected lesions or focus areas in the image, if the doctor finds that the drawn region of interest has deviations, the doctor needs to edit the region of interest to adjust the deviations. The adjustment method is single, and when multiple regions of interest in the image need to be drawn, it is easy to make mistakes or fail to draw another region of interest near the current region of interest. The region of interest cannot be effectively drawn, and the personalized needs of users cannot be met. Summary of the invention

[0005] In a first aspect, an embodiment of the present invention provides a method for triggering a region of interest, the method comprising:

[0006] Receiving an operation instruction for a target region of interest of a target object, and determining a trigger state of the target region of interest according to the operation instruction;

[0007] When a change in the trigger state is detected, the hot zone value of the target region of interest is switched from the current hot zone value to the target hot zone value corresponding to the trigger state.

[0008] In a second aspect, an embodiment of the present invention further provides a triggering device for a region of interest, the device comprising:

[0009] A trigger state determination module, configured to receive an operation instruction for a target region of interest of a target object, and determine a trigger state of the target region of interest according to the operation instruction;

[0010] The switching module is used to switch the hot zone value of the target area of ​​interest from the current hot zone value to the target hot zone value corresponding to the trigger state when a change in the trigger state is detected.

[0011] In a third aspect, an embodiment of the present invention further provides a device, the device comprising:

[0015] In a fourth aspect, an embodiment of the present invention further provides a storage medium comprising computer executable instructions, wherein the computer executable instructions, when executed by a computer processor, are used to execute any of the triggering methods for a region of interest described in the embodiments of the present invention.

[0016] The technical solution of the embodiment of the present invention can determine the trigger state of the target region of interest according to the received operation instruction on the target region of interest, so as to adjust its hot zone value according to the trigger state of the target region of interest later. When it is detected that the trigger state has changed, the hot zone value of the target region of interest is switched from the current hot zone value to the target hot zone value corresponding to the trigger state, so as to avoid the inconvenience of operating the target region of interest when the hot zone value of the target region of interest is fixed to a fixed value. In this way, the hot zone value of the target region of interest can be adjusted according to the trigger state of the target region of interest, so that the user can subsequently operate the target region of interest according to the different trigger states of the target region of interest, thereby improving the fluency of the operation on the target region of interest.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0026] Embodiment 1

[0027] Figure 1 This is a flow chart of a method for triggering a region of interest provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of operating a region of interest. The method can be executed by a triggering device for a region of interest. The triggering device for a region of interest can be implemented by software and / or hardware. The triggering device for a region of interest can be configured on a computing device. Specifically, the method includes the following steps:

[0028] Before introducing the technical solution of the embodiment of the present invention, the concept of hot zone value is first introduced. The user (for example, a doctor) will set a hot zone sensing range in the region of interest of the image. The hot zone sensitive range is called the hot zone value of the region of interest. When the mouse enters the hot zone sensing range, certain operations can be performed on the region of interest. For example, when the doctor finds that the range of the drawn region of interest is deviated, the region of interest needs to be edited to adjust the deviation. Figure 2 The schematic diagram of the target region of interest heat zone value representation is shown, in which box a is the target region of interest, and the distance between box a and another box b outside box a is the heat zone value of the target region of interest.

[0029] S110: Receive an operation instruction for a target region of interest of a target object, and determine a trigger state of the target region of interest according to the operation instruction.

[0030] Exemplarily, the target object may be an object on which an operation is to be performed on its target region of interest, for example, it may be a patient. The target region of interest may be an area on which an operation is performed on the image of the target object, for example, it may be a suspected lesion or a focus range area on which an operation is performed in a magnetic resonance image or a CT image of any patient. The operation instruction may be an instruction to perform an operation on the target region of interest of the target object, for example, it may be to edit the target region of interest or any other operation. The trigger state may be a state of whether the target region of interest is triggered, and may optionally include a to-be-triggered state and a triggered state. Based on the received operation instruction on the target region of interest, the trigger state of the target region of interest may be determined, so that its hot zone value may be adjusted subsequently according to the trigger state of the target region of interest.

[0031] S120: When it is detected that the trigger state changes, the hot zone value of the target region of interest is switched from the current hot zone value to the target hot zone value corresponding to the trigger state.

[0032] Exemplarily, the current hot zone value may be the hot zone value of the current state of the target region of interest. The target hot zone value may be the hot zone value when the target region of interest is in a certain trigger state. Since the hot zone value of the target region of interest in the prior art is a fixed value, and since doctors often need to edit or perform other operations on the target region of interest, the hot zone value of the target region of interest is generally set to be larger so as to operate the target region of interest. However, this may also cause the mouse to enter the hot zone value range of the target region of interest when performing other operations near the hot zone value of the current target region of interest, which may be mistakenly regarded as an operation on the target region of interest, thereby affecting the operation of other regions of interest. When the trigger state of the target region of interest changes, the current hot zone value of the target region of interest is switched to the target hot zone value corresponding to the trigger state, so as to avoid the inconvenience of operating the target region of interest when the hot zone value of the target region of interest is fixed to a fixed value, so that the hot zone value of the target region of interest can be adjusted according to the trigger state of the target region of interest, so that subsequent users can operate the target region of interest according to different trigger states of the target region of interest, thereby improving the fluency of the operation on the target region of interest.

[0033] The technical solution of the embodiment of the present invention can determine the trigger state of the target region of interest according to the received operation instruction on the target region of interest, so as to adjust its hot zone value according to the trigger state of the target region of interest later. When it is detected that the trigger state has changed, the hot zone value of the target region of interest is switched from the current hot zone value to the target hot zone value corresponding to the trigger state, so as to avoid the inconvenience of operating the target region of interest when the hot zone value of the target region of interest is fixed to a fixed value. In this way, the hot zone value of the target region of interest can be adjusted according to the trigger state of the target region of interest, so that the user can subsequently operate the target region of interest according to the different trigger states of the target region of interest, thereby improving the fluency of the operation on the target region of interest.

[0034] Embodiment 2

[0035] Figure 3 This is a flow chart of a method for triggering a region of interest provided in Embodiment 2 of the present invention. This embodiment of the present invention is a further optimization of the above embodiment based on the above embodiment, and specifically includes the following steps:

[0036] S210: receiving a selection instruction for a target region of interest of a target object, receiving an edit trigger instruction for the selected target region of interest, and determining a trigger state of the target region of interest as a triggered state according to the edit trigger instruction.

[0037] Exemplary, reference Figure 4 The schematic diagram shows whether the target area of ​​interest is selected. Figure 4 The box a in the middle is the target area of ​​interest, where Figure 4 Figure a in the figure is a schematic diagram of the unselected target area of ​​interest. Figure 4 Figure b in the figure shows a schematic diagram of the selected target area of ​​interest, such as Figure 4 As shown in Figure a, when the mouse does not enter the hot zone value range of the target area of ​​interest, it means that the target area of ​​interest is not selected, such as Figure 4 As shown in Figure b, when the mouse enters the hot zone value range of the target area of ​​interest, it means that the target area of ​​interest is selected.

[0038] Exemplarily, the selection instruction may be an instruction generated by selecting the target region of interest. Specifically, the selection instruction may be an instruction generated by selecting the target region of interest. Specifically, the selection instruction may be an instruction generated by selecting the target region of interest. Figure 4As shown in Figure b, the mouse may be located within the hot zone value range of the target region of interest, which indicates that the target region of interest is selected, and then a selection instruction is generated. The edit trigger instruction may be an instruction generated based on the selection operation of the target region of interest of the target object. When the selection instruction of the target region of interest is received, an edit trigger instruction of the target region of interest may be generated, so that when the target region of interest of the target object is selected, an edit trigger instruction may be generated, so that the trigger state of the target region of interest is subsequently determined based on the edit trigger instruction. When an edit trigger instruction for the target region of interest of the target object is received, the trigger state of the target region of interest is determined to be a triggered state, that is, when the target region of interest is selected, the target region of interest is in a triggered state, and when the target region of interest is in the triggered state, its hot zone value is a trigger hot zone value, and it can be directly operated on it at this time, without having to edit the drawn target region of interest as before. For example, when modifying the target region of interest, the target region of interest must first be selected, and then the editing state is triggered through the right-click menu or button of the target region of interest. In this solution, the target region of interest can be directly edited by selecting it, which can reduce the user's operation steps and quickly edit the target region of interest, saving time and improving the efficiency of editing the target region of interest.

[0039] The above embodiment can be applied to a practical scenario. For example, a doctor performs a CT scan of the lungs for a patient. In order to further observe the patient's lung condition, the doctor will make a diagnosis on the patient's CT medical image. Specifically, it is necessary to draw certain regions of interest, such as suspected lesions, in the CT medical image and extract their range features. After drawing a certain suspected lesion (equivalent to the target region of interest), if the doctor finds that the extracted target region of interest has a deviation, it is necessary to edit the drawn target region of interest to adjust the deviation. At this time, it is not necessary to select the target region of interest first, and then trigger the editing state through the right-click menu or button of the target region of interest to adjust the target region of interest. Instead, the target region of interest is directly selected to switch to the state of editing the target region of interest. At this time, after the target region of interest is selected, the target region of interest is in a triggered state, and the hot zone value of the target region of interest is the trigger hot zone value. The doctor can directly adjust the target region of interest, thereby reducing the doctor's operation steps and quickly and effectively editing the target region of interest. At the same time, time is saved and the efficiency of editing the target region of interest is improved.

[0040] S220: When it is detected that the trigger state changes, the hot zone value of the target region of interest is switched from the current hot zone value to the target hot zone value corresponding to the trigger state.

[0041] The technical solution of the embodiment of the present invention can generate an editing trigger instruction for the selected target area of ​​interest when a selection instruction for the target area of ​​interest of the target object is received, and determine the trigger state of the target area of ​​interest as a triggered state according to the editing trigger instruction. When the target area of ​​interest is in the triggered state, its hot zone value is a trigger hot zone value, and it can be directly operated at this time, instead of having to first select the target area of ​​interest and then trigger the editing state through the right-click menu or button of the target area of ​​interest to edit the drawn target area of ​​interest as before. The target area of ​​interest in this solution can be directly edited after it is selected, which can reduce the user's operation steps and quickly edit the target area of ​​interest, saving time and improving the efficiency of editing the target area of ​​interest.

[0042] Embodiment 3

[0043] Figure 5 This is a flowchart of a method for triggering a region of interest provided in Embodiment 3 of the present invention. This embodiment of the present invention is a further optimization of the above embodiment based on the above embodiment, and specifically includes the following steps:

[0044] S310: Receive a selection instruction for a target region of interest of a target object, receive an edit trigger instruction for the selected target region of interest, and determine a trigger state of the target region of interest as a triggered state according to the edit trigger instruction.

[0045] S320: When it is detected that the trigger state changes from the to-be-triggered state to the triggered state, the hot zone value of the target region of interest is switched from a default hot zone value to a trigger hot zone value, wherein the trigger hot zone value is greater than the default hot zone value.

[0046] Exemplarily, the default hot zone value may be the hot zone value set when the target region of interest is in the to-be-triggered state, and the default hot zone value may be verified by the user's actual operation to see if it is acceptable, and the default hot zone value may be adjusted by configuration according to the user's experience and habits, and is not limited here. The trigger hot zone value may be the hot zone value when the target region of interest is in the triggered state, and the trigger hot zone value may be verified by the user's actual operation to see if it is acceptable, and the trigger hot zone value may be adjusted by configuration according to the user's experience and habits, and is not limited here. The trigger hot zone value here is greater than the default hot zone value. Because when operating on the target region of interest, the hot zone value of the target region of interest must exceed a certain threshold, such as 120deg, to effectively operate on the target region of interest, the hot zone value of the existing method is a fixed value, regardless of whether the target region of interest is triggered, the hot zone value is fixed, so if the fixed hot zone value is set too small, the target region of interest cannot be effectively operated. If the fixed hot zone value is too small, when the target region of interest is not operated, but the position next to the target region of interest needs to be operated, it will be received that the target region of interest needs to be operated, and other operations cannot be performed at the position next to it. Here, when the trigger state of the target region of interest changes from the waiting state to the triggered state, the hot zone value of the target region of interest is switched from the default hot zone value to the trigger hot zone value, so that the hot zone value of the target region of interest can be adjusted according to the trigger state of the target region of interest. When the target region of interest is in the waiting state, the hot zone value of the target region of interest is the default hot zone value. Generally speaking, the default hot zone value is generally set to be small, usually less than the threshold value, so that when the target is not interested in operating, the hot zone value of the target region of interest is small, so that other operations can be performed next to the target region of interest. When the target region of interest is in the triggered state, the hot zone value of the target region of interest is the trigger hot zone value. Generally speaking, the trigger hot zone value is generally set to be large, usually greater than the threshold value, so that when the target is interested in operating, the hot zone value of the target region of interest is large, so that the target region of interest can be effectively operated. The operability and fluency of the target region of interest are improved, and a good user experience is provided.

[0047] On the basis of the technical solution of the above embodiment, when it is detected that the trigger state changes, the hot zone value of the target area of ​​interest is switched from the current hot zone value to the target hot zone value corresponding to the trigger state. It can also be: when it is detected that the trigger state changes from the triggered state to the to-be-triggered state, the hot zone value of the target area of ​​interest is switched from the trigger hot zone value to the default hot zone value.

[0048] Exemplarily, when the trigger state of the target region of interest changes from the triggered state to the to-be-triggered state, the hot zone value of the target region of interest is switched from the trigger hot zone value to the default hot zone value, so that the hot zone value of the target region of interest can be adjusted according to the trigger state of the target region of interest. When the target region of interest is in the triggered state, the hot zone value of the target region of interest is the trigger hot zone value, so that when the target region of interest is operated with interest, the hot zone value of the target region of interest is large, so that the target region of interest can be operated effectively. When the target region of interest is in the to-be-triggered state, the hot zone value of the target region of interest is the default hot zone value, so that when the target region of interest is not operated with interest, the hot zone value of the target region of interest is small, so that other operations can be performed at the position next to the target region of interest, thereby improving the operability and fluency of the target region of interest and providing a good user experience.

[0049] Optionally, when an adding instruction to add a new region of interest in the target object is received, the hot zone value of the target region of interest is determined as a default hot zone value.

[0050] Exemplarily, the newly added region of interest may be to add another or several regions of interest in the image of the target object. The adding instruction may be an instruction to add another or several regions of interest in the image of the target object. When an adding instruction to add a newly added region of interest in the target object is received, it is not necessary to operate the target region of interest at this time, and therefore, the hot zone value of the target region of interest is determined as a default hot zone value, so that the newly added region of interest can be added to the target object without affecting the target region of interest.

[0051] refer to Figure 6 The schematic diagram of adding a new area of ​​interest is shown in the figure, where: Figure 6 Figure a in the figure shows a schematic diagram of adding a new region of interest in the prior art. Figure 6 Figure b in the figure shows a schematic diagram of adding a new region of interest in an embodiment of the present invention. Figure 6 As shown in Figure a, the box a in the figure represents the target region of interest. When another newly added region of interest b needs to be drawn at position Q close to the target region of interest a, due to the large hot zone value of the target region of interest a (the range between the box a in the figure and the box outside the box a), the mouse drawing pen will collide with the hot zone value range of the target region of interest a, and it will be mistakenly believed that the mouse selection is to operate on the target region of interest a, and the newly added region of interest b cannot be added accurately or at all.

[0052] like Figure 6As shown in Figure b, the box a in the figure is the target area of ​​interest, the dotted box in the figure is the default hot zone value of the target area of ​​interest, and the solid box outside the dotted box is the trigger hot zone value of the target area of ​​interest. When an add instruction to add a new area of ​​interest to the target object is received, for example, the add instruction can be to add a new area of ​​interest b at point M of the target area of ​​interest of the target object, and point M is located between the dotted box and the solid box. Then, according to the add instruction, the hot zone value of the target area of ​​interest is determined as the default hot zone value, and the user can directly add the new area of ​​interest b outside the default hot zone value (dotted box) of the target area of ​​interest. Avoid Figure 6 The situation shown in Figure a occurs, and a new ROI cannot be added near the target ROI.

[0053] Applying the above embodiment to a practical scenario, for example, a doctor may perform a CT scan of the patient's lungs. In order to further observe the patient's lung condition, the doctor will diagnose the patient's CT medical image. Specifically, it is necessary to draw certain regions of interest, such as suspected lesions, in the CT medical image and extract their range features. After drawing a suspected lesion (equivalent to the target region of interest), if the doctor finds that another suspected lesion region (a newly added region of interest) needs to be drawn very close to the target region of interest, then at this time, just move the mouse to a position that is not the target region of interest. At this time, the hot zone value of the target region of interest is the default hot zone value, and the doctor can directly draw the newly added region of interest very close to the target region of interest.

[0054] It should be noted that when the doctor finds that another suspected lesion area (newly added area of ​​interest) needs to be drawn very close to the target area of ​​interest, the mouse is positioned at a position that is not the target area of ​​interest. This is not limited to a mouse, but can also be a finger or a sensor pen during touch screen operation. Of course, other positioning methods besides the above methods can also be used, which are not limited here.

[0055] According to the technical solution of the embodiment of the present invention, when the trigger state of the target region of interest changes from the to-be-triggered state to the triggered state, the hot zone value of the target region of interest is switched from the default hot zone value to the trigger hot zone value, and when the trigger state of the target region of interest changes from the triggered state to the to-be-triggered state, the hot zone value of the target region of interest is switched from the trigger hot zone value to the default hot zone value, so that the hot zone value of the target region of interest can be adjusted according to the trigger state of the target region of interest, and when the target region of interest is in the triggered state, the hot zone value of the target region of interest is the trigger hot zone value, so that when the target region of interest is operated with interest, the hot zone value of the target region of interest is large, so that the target region of interest can be operated effectively. When the target region of interest is in the to-be-triggered state, the hot zone value of the target region of interest is the default hot zone value, so that when the target region of interest is not operated with interest, the hot zone value of the target region of interest is small, so that other operations can be performed at the position next to the target region of interest, thereby improving the operability and fluency of the target region of interest and providing a good user experience. When an add instruction to add a new region of interest in the target object is received, no operation is required on the target region of interest at this time, and the hot zone value of the target region of interest is determined as the default hot zone value, so that the new region of interest can be added to the target object without affecting the target region of interest.
