Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultrasound, in particular to a lesion position marking method, an ultrasound device and a storage medium. BACKGROUND

[0002] The anal clock positioning method divides the anus of the examinee into 12 equal parts according to the rule of clock timing, so as to accurately position the lesion. The anal clock positioning method can help doctors better understand the position of the past perianal diseases (tumor, ulcer and bleeding, etc.) of the examinee, is conducive to more standardized writing of medical records, re-examination, and also makes the surgical planning more accurate.

[0003] During the examination, the doctor may choose different body positions for examination according to the patient or the disease, including lithotomy position, left lateral position and knee chest position. The clock position of each body position is consistent, but the specific position of the clock corresponding to the human body is different. For example, the 6 o'clock direction of the lithotomy position and the 12 o'clock direction of the knee chest position represent the same position of the human body.

[0004] In the current technical solution, the doctor needs to mark the lesion based on the "body position + clock number" description during the examination, and the doctor needs to obtain the position of the lesion based on the "body position + clock number" description during the operation. On the one hand, the text description is not intuitive and is not convenient for doctors to quickly obtain the position of the lesion. On the other hand, the body position during the operation may not be consistent with the body position during the examination. For example, the doctor generally operates in the lithotomy position during the operation, and at this time the doctor needs to convert the "body position + clock number" to the corresponding lithotomy position, and then obtain the position of the lesion. The conversion rules of different body positions and the lithotomy position are different and need to be learned and remembered, so it is not convenient for doctors to quickly obtain the position of the lesion. Therefore, a new technical solution is needed. SUMMARY

[0063] The present application will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; the relevant operations can be fully understood based on the description in the specification and general technical knowledge in the art.

[0064] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0065] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0066] In some embodiments of this application, lesions on the subject are marked based on a lesion location marking map. The examination position elements of the lesion location marking map represent the target area being examined when the subject is in the corresponding examination position. The clock image of the lesion location marking map represents the various orientations of the lesion, allowing the doctor to intuitively obtain positional and orientational information. Simultaneously, the relative positional relationship between the examination position elements and the clock image ensures that any clock direction on the clock image corresponds to the actual orientation of the subject's body. This further allows the doctor to intuitively see the actual orientation of the subject's body corresponding to the positional and orientational information. The lesion location markings on the lesion location marking map correspond to a clock direction on the clock image, enabling the doctor to intuitively obtain the lesion's actual orientation within the subject's body based on the lesion location markings, thus facilitating the doctor's rapid determination of the lesion's location. Furthermore, when the acquired lesion location marker is not the expected lesion location marker, the examination position elements, clock image, and lesion location marker corresponding to the expected lesion location marker are acquired, and the expected lesion location marker is generated for output. This allows doctors to quickly obtain the location of the lesion based on the expected lesion location marker without having to change the examination position.

[0067] Some embodiments provide an ultrasound device that, during ultrasound imaging, can mark the location of lesions in a target area of ​​the patient, allowing the physician to quickly determine the lesion's location on the body based on the marked location. Please refer to... Figure 1 The ultrasonic device includes an ultrasonic probe 10, a transmission and reception control circuit, a processor 20, a human-computer interaction device 70, and a memory 80, which will be described in detail below.

[0068] An ultrasound probe 10 is used to transmit ultrasound waves toward a region of interest and to receive the echo signals of the corresponding ultrasound waves. The ultrasound probe 10 includes a transducer (not shown) composed of multiple array elements arranged in an array. Each array element is used to transmit ultrasound waves according to an excitation electrical signal, or to convert received ultrasound waves into electrical signals. Therefore, each array element can be used to achieve the mutual conversion between electrical pulse signals and ultrasound waves, thereby enabling the transmission of ultrasound waves toward the biological tissue of the scanned object, and it can also be used to receive the echoes of ultrasound waves reflected back from the tissue.

[0069] The transmitting and receiving control circuit is used to control the ultrasonic probe 10 to transmit ultrasonic waves and receive the echo signals of ultrasonic waves. The transmitting and receiving control circuit may include a transmitting circuit 30 and a receiving circuit 40. The transmitting circuit 30 is used to excite the ultrasonic probe 10 to transmit ultrasonic waves toward the scanned object according to the control of the processor 20. The receiving circuit 40 is used to receive the ultrasonic echo returned from the scanned object through the ultrasonic probe 10 to obtain the echo signal of the ultrasonic waves, and can also process the echo signal of the ultrasonic waves.

[0070] The human-computer interaction device 70 is used for human-computer interaction, such as outputting visual information and receiving user input. It can receive user input using a keyboard, operation buttons, mouse, trackball, touchpad, or a touchscreen integrated with the display; it can output visual information using a display, touchscreen display, screen, or touchscreen display.

[0071] The memory 80 is used to store various types of data.

[0072] Please refer to Figure 1 The ultrasound equipment may also include a beamforming module 50 and an IQ demodulation module 60.

[0073] The beamforming module 50 is signal-connected to the receiving circuit 40 and is used to perform beamforming processing on the echo signal, including delay and weighted summation. Because the distance from the ultrasonic receiving point in the tested tissue to the receiving array elements varies, the channel data of the same receiving point output by different receiving array elements has delay differences, requiring delay processing to align the phases. Weighted summation of the different channel data of the same receiving point is then performed to obtain the beamformed ultrasonic image data. The ultrasonic image data output by the beamforming module 50 is also called radio frequency (RF) data. The beamforming module 50 outputs the RF data to the IQ demodulation module 60. In some embodiments, the beamforming module 50 may also output the RF data to the memory 80 for caching or storage, or directly output the RF data to the processor 20 for image processing.

[0074] The beamforming module 50 can perform the above functions using hardware, firmware, or software. The beamforming module 50 can be integrated into the processor 20 or configured separately; this invention does not impose any limitations on this.

[0075] The IQ demodulation module 60 removes the signal carrier through IQ demodulation, extracts the tissue structure information contained in the signal, and filters to remove noise. The signal obtained at this time is called the baseband signal (IQ data pair). The IQ demodulation module 60 outputs the IQ data pair to the processor 20 for image processing. In some embodiments, the IQ demodulation module 60 also outputs the IQ data pair to the memory 80 for buffering or storage, so that the processor 20 can read the data from the memory 80 for subsequent image processing.

[0076] The IQ demodulation module 60 can also perform the above functions in hardware, firmware, or software. Similarly, the IQ demodulation module 60 can be integrated into the processor 20 or set up separately; this invention does not impose any limitations on this.

[0077] The processor 20 is configured to process input data according to specific logic instructions. It is a central controller circuit (CPU), one or more microprocessors 20, a graphics controller circuit (GPU), or any other electronic component. It can control peripheral electronic components according to input instructions or predetermined instructions, or perform data reading and / or saving on the memory 80. It can also process input data by executing programs in the memory 80. For example, it can perform one or more processing operations on the acquired ultrasound data according to one or more operating modes. The processing operations include, but are not limited to, adjusting or limiting the form of ultrasound waves emitted by the ultrasound probe 10, generating various image frames for display on the display of the human-machine interface device 70, or adjusting or limiting the content and form displayed on the display, or adjusting one or more image display settings displayed on the display (e.g., ultrasound images, interface components, locating regions of interest).

[0078] When an echo signal is received, the acquired ultrasound data can be processed in real time by the processor 20 during the scan, or it can be temporarily stored in the memory 80 and processed in a near real-time manner during online or offline operation.

[0079] In this embodiment, the processor 20 controls the operation of the transmitting circuit 30 and the receiving circuit 40, for example, controlling the transmitting circuit 30 and the receiving circuit 40 to operate alternately or simultaneously. The processor 20 can also determine a suitable operating mode according to the user's selection or the program settings, form a transmission sequence corresponding to the current operating mode, and send the transmission sequence to the transmitting circuit 30 so that the transmitting circuit 30 can use the appropriate transmission sequence to control the ultrasonic probe 10 to emit ultrasonic waves.

[0080] The above is a brief description of ultrasound equipment. The following is a detailed explanation of the process of marking lesions using ultrasound equipment.

[0081] The processor first obtains the target part of the examinee and the corresponding image to be marked in the examinee's current position during the current examination.

[0082] In some embodiments, the target area may be the perianal area, and the subject may be examined in at least two different positions, such as the lithotomy position, left lateral decubitus position, and knee-chest position for perianal examination.

[0083] In some embodiments, the images to be labeled corresponding to the examined body position include at least two types. These images include at least a first image to be labeled, a second image to be labeled, and a third image to be labeled, which will be described in detail below.

[0084] Please refer to Figure 2The first image to be labeled is the image corresponding to the first examination position, which includes a first examination position element and a first clock image, as well as a first relative positional relationship between the first examination position element and the first clock image. The first examination position element is used to characterize the target area of ​​the examinee being examined when the examinee is in the first examination position. For example, the first examination position element can be a morphological diagram characterizing the perianal area, which is consistent with at least a portion of the shape of the perianal area of ​​the human body in the first examination position. The first clock image has multiple clock directions, such as a 1 o'clock clock direction to a 12 o'clock clock direction, where each clock direction represents a different orientation. The first relative positional relationship between the first examination position element and the first clock diagram is used to characterize any clock direction on the first clock diagram relative to the actual body direction of the examinee. That is, the first relative positional relationship is determined by the first examination position. For example, when the first image to be marked corresponds to the knee-chest position, the bottom of the perianal area of ​​the human body in the knee-chest position is located at the 12 o'clock position. Based on this first relative positional relationship, the 12 o'clock position of the first clock diagram points to the bottom of the perianal area of ​​the human body in the knee-chest position as represented by the first examination position element. Therefore, any clock direction on the first clock diagram corresponds to the actual body direction of the examinee. In this embodiment, the first image to be marked, based on the first examination position element and the first clock diagram, can not only intuitively express the various positions of the examinee's knee-chest and perianal areas, but also, based on the first relative positional relationship, ensures that any clock direction on the first clock diagram corresponds to the actual body direction of the examinee. Thus, it can also intuitively express the various positions of the perianal area corresponding to the examinee in the knee-chest position.

[0085] Please refer to Figure 3The second image to be marked is the image corresponding to the second examination position, which includes a second examination position element and a second clock image, as well as a second relative positional relationship between the second examination position element and the second clock image. The second examination position element is used to characterize the target area of ​​the examinee being examined when the examinee is in the second examination position. For example, the second examination position element can be a morphological diagram characterizing the perianal area, which is consistent with at least a portion of the shape of the perianal area of ​​the human body in the second examination position. The second clock image has multiple clock directions, such as a 1 o'clock direction to a 12 o'clock direction, where each clock direction represents a different orientation. In some embodiments, the second examination position element and the first examination position element can have the same shape. For example, when the first image to be marked corresponds to the knee-chest position and the second image to be marked corresponds to the left lateral decubitus position, the second examination position element can be obtained by rotating the first examination position element counterclockwise by 90 degrees. In some embodiments, the second examination position element and the first examination position element can also have different shapes, but both are consistent with at least a portion of the shape of the perianal area. In some embodiments, the second clock pattern may be the same as the first clock pattern. In some embodiments, the second clock pattern may differ in shape from the first clock pattern, but the orientation of each clock direction is consistent; for example, the 6 o'clock position in both the second and first clock patterns points vertically downwards.

[0086] The second relative positional relationship between the second examination position element and the second clock diagram is used to characterize any clock direction on the second clock diagram relative to the actual body direction of the examinee. For example, when the second image to be marked corresponds to the left lateral decubitus position, the bottom of the perianal area of ​​the human body in the left lateral decubitus position is located at the 9 o'clock position. Based on this second relative positional relationship, the 9 o'clock position of the second clock diagram points to the bottom of the perianal area of ​​the human body in the left lateral decubitus position represented by the second examination position element. Therefore, any clock direction on the second clock diagram corresponds to the actual body direction of the examinee. In this embodiment, the second image to be marked, based on the second examination position element and the second clock diagram, can not only intuitively express the various positions of the examinee's left lateral decubitus position and perianal area, but also, based on the second relative positional relationship, ensures that any clock direction on the second clock diagram corresponds to the actual body direction of the examinee. Thus, it can also intuitively express the various positions of the perianal area corresponding to the examinee in the left lateral decubitus position.

[0087] Please refer to Figure 4The third image to be marked is the image corresponding to the third examination position, which includes a third examination position element and a third clock image, as well as a third relative positional relationship between the third examination position element and the third clock image. The third examination position element is used to characterize the target area of ​​the examinee being examined when the examinee is in the third examination position. For example, the third examination position element can be a morphological diagram characterizing the perianal area, which is consistent with at least a portion of the shape of the perianal area of ​​the human body in the third examination position. The third clock image has multiple clock directions, such as a 1 o'clock direction to a 12 o'clock direction, where each clock direction represents a different orientation. In some embodiments, the third examination position element and the first examination position element can have the same shape. For example, when the first image to be marked corresponds to the knee-chest position and the third image to be marked corresponds to the lithotomy position, the third examination position element can be obtained by rotating the first examination position element 180 degrees. In some embodiments, the third examination position element and the first examination position element can also have different shapes, but both are consistent with at least a portion of the shape of the perianal area. In some embodiments, the third clock diagram may be the same as the first clock diagram. In some embodiments, the third clock diagram may differ in shape from the first clock diagram, but the orientation of each clock direction is consistent; for example, the 6 o'clock position in both the third clock diagram and the first clock diagram points vertically downwards.

[0088] The third relative positional relationship between the third examination position element and the third clock diagram is used to characterize any clock direction on the third clock diagram relative to the actual direction of the examinee's body. For example, when the third diagram to be marked corresponds to the lithotomy position, the bottom of the perianal area of ​​the human body in the lithotomy position is located at the 6 o'clock position. At this time, based on the third relative positional relationship, the 6 o'clock position of the third clock diagram points to the bottom of the perianal area of ​​the human body in the left lateral decubitus position represented by the third examination position element, so that any clock direction of the third clock diagram corresponds to the actual direction of the examinee's body. In this embodiment, the third diagram to be marked, based on the third examination position element and the third clock diagram, can not only intuitively express the various orientations of the examinee's lithotomy position and perianal area, but also, based on the third relative positional relationship, ensure that any clock direction of the third clock diagram corresponds to the actual direction of the examinee's body, thus intuitively expressing the various orientations of the perianal area of ​​the examinee in the lithotomy position.

[0089] In the above embodiments, when the examinee's examination position is the knee-chest position, the processor acquires the first image to be labeled corresponding to the knee-chest position. When the examinee's examination position is the left lateral decubitus position, the processor acquires the second image to be labeled corresponding to the left lateral decubitus position. When the examinee's examination position is the lithotomy position, the processor acquires the third image to be labeled corresponding to the lithotomy position. In some embodiments, when the examinee's examination position is other than the knee-chest position, acquiring the image to be labeled corresponding to the other position is sufficient.

[0090] The processor controls the human-computer interaction device to display the map to be marked corresponding to the current examination position of the examinee, so as to mark the location of the lesion in the perianal area of ​​the examinee under the current examination position and obtain the corresponding lesion location marking map.

[0091] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the processor, in response to a user's operation on the image to be marked, marks the lesion location on the image to be marked, thereby obtaining a lesion location marking image. In some embodiments, the user can operate on the clock image in the image to be marked using touch operation, button operation, or cursor click operation, and mark the lesion location in the corresponding clock direction of the clock image, thereby indicating that the actual body direction of the examinee represented by the clock direction is the direction in which the lesion is located.

[0092] In some embodiments, when marking lesion locations on the image to be marked, the processor can add a lesion circle in the corresponding clock direction of the clock image as a lesion location marker. The lesion circle can also be replaced with other forms of markers, such as squares, triangles, or other shapes, or symbols, letters, numbers, text, or other representations. In some embodiments, the processor can also adjust the corresponding clock position on the clock image and use it as a lesion location marker, for example, by making the clock position bold or highlighting it. In some embodiments, in response to user operations on the lesion location marker, the processor can also adjust the corresponding clock direction of the lesion location marker in the clock image.

[0093] The above is an explanation of how to mark lesions based on the image to be marked and obtain a lesion location marking map.

[0094] However, since the current examination position for lesion marking may not be the expected position for surgical treatment, such as the expected lithotomy position, directly outputting the lesion location marking map corresponding to the current examination position for subsequent surgical treatment would also affect the surgeon's ability to quickly obtain the lesion's location on the body. Therefore, in some embodiments of this application, when the current examination position is not the expected examination position, it is necessary to output the lesion location marking map corresponding to the expected examination position, thereby further facilitating the surgeon's rapid acquisition of the lesion's location on the body. The process of outputting the lesion location marking map corresponding to the lithotomy position is described in detail below.

[0095] The processor first acquires a lesion location marker map corresponding to the current examination position. This map can be used to represent the actual orientation of the lesion relative to the examinee's body. For example, it can acquire a first lesion location marker map relative to the examinee. The first lesion location marker map includes a first examination position element, a first clock image, and a first lesion location marker, as well as a first relative positional relationship between the first examination position element and the first clock image. For example, the first lesion location marker map can be obtained by adding the first lesion location marker to a first map to be marked, which will not be elaborated further here.

[0096] The processor then executes the expected examination position output function and determines whether the first lesion location marker map is the expected second lesion location marker map, for example, whether the first lesion location marker map is the lesion location marker map corresponding to the lithotomy position. In some embodiments, it can be determined whether the first examination position corresponding to the first examination position element of the first lesion location marker map is the lithotomy position. If the first examination position is not the lithotomy position, then the first lesion location marker map is not the expected second lesion location marker map.

[0097] At this point, the processor acquires the second lesion location marker map corresponding to the lithotomy position. In some embodiments, the processor may first acquire the map to be marked corresponding to the lithotomy position in the above embodiments, which will not be repeated here. In some embodiments, the processor may also first acquire the second examination position element and the second clock image of the second lesion location marker map, as well as the second relative positional relationship between the second examination position element and the second clock image. The second examination position element, the second clock image, and the second relative positional relationship can be referred to the above embodiments, wherein the second examination position element represents the lithotomy position, which will not be repeated here.

[0098] The processor then generates a second lesion location marker in the second lesion location marker map, representing the lesion's location relative to the second clock map, based on the first lesion location marker in the first lesion location marker map.

[0099] In some embodiments, the processor obtains the actual orientation of the lesion relative to the examinee's body based on the first lesion location marker in the first lesion location marker image, which represents the lesion's first location relative to the first clock image. Then, based on this actual orientation, it generates a second lesion location marker in the second lesion location marker image, representing the lesion's second location relative to the second clock image. In this embodiment, both the first and second lesion location marker images are used to represent the actual orientation of the lesion relative to the examinee's body. Therefore, after obtaining the actual orientation based on the first lesion location marker image, the second lesion location marker relative to the second clock image can be obtained from this actual orientation. For example, please refer to... Figure 2 and Figure 4 When the first lesion location marker corresponds to the knee-chest position, the first location marker corresponds to the 12 o'clock position of the first clock image. The 12 o'clock position of the first lesion location marker indicates the bottom of the perianal area. Based on the bottom of the perianal area, it can be obtained that the second lesion location marker in the lithotomy position corresponds to the 6 o'clock position. Thus, the second location marker corresponds to the 6 o'clock position of the second clock image.

[0100] In some embodiments, the processor obtains the mapping relationship between the first examination position and the second examination position, and then, based on this mapping relationship, maps the clock direction of the first lesion location marker on the first clock image to obtain the clock direction of the second lesion location marker on the second clock image, so as to generate a second lesion location marker in the second lesion location marker image representing the lesion relative to the second clock image. In this embodiment, each examination position can be converted to another, so the first examination position and the second examination position can also be converted to another, and there is a certain mapping relationship between the first examination position and the second examination position, so that the first lesion location marker and the second lesion location marker also have the same mapping relationship. Therefore, based on this mapping relationship, the second lesion location marker in the second lesion location marker image can be obtained from the first lesion location marker in the first lesion location marker image. For example, please refer to... Figure 2 and Figure 4 When the first lesion location marker corresponds to the knee-chest position, there is a 180-degree mapping relationship between the knee-chest position and the lithotomy position. That is, rotating the knee-chest position by 180 degrees yields the lithotomy position. Then, rotating the first lesion location marker in the first lesion location marker diagram by 180 degrees also yields the second lesion location marker in the second lesion location marker diagram corresponding to the lithotomy position. For example, if the first location marker corresponds to the 12 o'clock position in the first clock diagram, rotating it by 180 degrees gives the second location marker, which corresponds to the 6 o'clock position in the second clock diagram.

[0101] Finally, the processor generates a second lesion location marker map based on the second examination position element, the second clock diagram, the second relative position relationship, and the second lesion location marker.

[0102] In some embodiments, the processor configures the positions of the second examination position element and the second clock diagram according to the second relative position relationship, such that any clock direction on the second clock diagram is relative to the actual direction of the examinee's body, and configures the second lesion position mark in the clock direction corresponding to the second clock diagram according to the second relative position relationship, the second examination position element and the second clock diagram, such that the clock direction where the second position mark is located is the actual direction of the lesion on the examinee's body, thereby obtaining the second lesion position mark diagram.

[0103] In some embodiments, the processor may automatically execute the desired examination position output function of the above embodiments, for example, automatically after obtaining the lesion location marker map corresponding to the current examination position. In some embodiments, the processor may also execute the desired examination position output function in response to the user's operation on the target examination position output key, thereby enabling the output of the user's desired examination position through a single key operation. In some embodiments, the target examination position output key may be a physical button on a control panel or a virtual button on a touch panel.

[0104] The processor outputs the second lesion location marker map of the above embodiment, so that after the surgeon obtains the second lesion location marker map, the lithotomy position represented by the second lesion location marker map is consistent with the patient's position during the surgery. Thus, the actual direction of the lesion on the patient's body can be intuitively obtained through the second lesion location marker map, without the need to change the examination position or to correspond to the relationship of "position + hour". This makes it easier for the doctor to quickly obtain the location of the lesion, improving the doctor's work efficiency and experience.

[0105] The above are some explanations of one method for outputting the lesion location marker diagram corresponding to the lithotomy position. The following is a detailed explanation of another method.

[0106] The processor first controls the lesion location marker map corresponding to the current examination position of the human-computer interaction device. This map can be used to represent the actual direction of the lesion relative to the examinee's body, for example, obtaining a first lesion location marker map relative to the examinee. The first lesion location marker map includes a first examination position element, a first clock image, and a first lesion location marker, as well as a first relative positional relationship between the first examination position element and the first clock image. For example, the first lesion location marker map can be obtained by marking the lesion on a first image to be marked, which will not be elaborated further here.

[0107] The processor, in response to user operation of the examination position function key group, identifies the target examination position to be output from multiple different examination positions. The target examination position is different from the first examination position. In some embodiments, the examination position function key group is part of the human-computer interaction device and may be one or more physical buttons, a physical trackball, one or more virtual buttons, or a virtual trackball. In some embodiments, the examination position function key group can be operated by the user to output multiple different examination positions, such as one of the lithotomy position, left lateral decubitus position, and knee-chest position.

[0108] In some embodiments, the processor, in response to a user's operation on the examination position function key group, rotates the first examination position element based on the center of the first clock image, and obtains the target examination position to be output based on the rotated first examination position element. In this embodiment, since the various examination positions can be converted to each other, for example, rotating one examination position can obtain other examination positions, so rotating the first examination position element by different angles can correspond to different examination positions. For example, when the first lesion location marker map corresponds to the left lateral decubitus position, rotating the first examination position element 90 degrees clockwise can correspond to the knee-chest position, while rotating the first examination position element 90 degrees counterclockwise can correspond to the lithotomy position.

[0109] In some embodiments, the processor, in response to a first operation by the user on the examination position function key group, rotates the first examination position element based on the center of the first clock image; in response to a second operation by the user on the examination position function key group, it stops the rotation of the first examination position element. In some embodiments, the examination position function key group can be continuously triggered, and the first examination position element can be continuously rotated based on the center of the first clock image during triggering, and the rotation of the first examination position element can be stopped when the examination position function key group stops being triggered. In some embodiments, the examination position function key group can also be rotated, and the first examination position element can be rotated by a corresponding rotation angle based on the rotation angle of the examination position function key group.

[0110] In some embodiments, the processor, in response to each third operation by the user on the examination position function key group, rotates the first examination position element by a preset angle based on the center of the first clock image. For example, each time the first examination position element is rotated 90 degrees clockwise based on the center of the first clock image, it can also be rotated 90 degrees counterclockwise, or it can be rotated 180 degrees or 270 degrees, that is, different angles and directions of rotation can be designed as needed.

[0111] In some embodiments, the processor may also respond to user operations on the examination position function key group, controlling the human-computer interaction device to display multiple different examination positions, and confirming the target examination position to be output from among the multiple different examination positions. For example, multiple different examination positions may be displayed simultaneously, and the target examination position to be output may be confirmed from among them. For example, one examination position may be displayed, and multiple different examination positions may be switched between display, with the currently displayed examination position confirmed as the target examination position to be output.

[0112] The processor generates a target lesion location map based on the target examination position and the first lesion location map.

[0113] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, if the user's operation on the examination position function key group involves rotating the first examination position element, the processor obtains the rotation angle of the first examination position element and rotates the first lesion position mark based on the center of the clock diagram. The target lesion position mark map is then obtained from the rotated first examination position element, the rotated first lesion position mark, and the first clock diagram. In this embodiment, rotating the first examination position element yields the examination position element corresponding to the target examination position. For example, when the first lesion position mark map corresponds to the left lateral decubitus position, rotating the first examination position element 90 degrees clockwise yields the examination position element corresponding to the knee-chest position, while rotating the first examination position element 90 degrees counterclockwise yields the examination position element corresponding to the lithotomy position. Furthermore, the first examination position element is rotated based on the center of the first clock image. Therefore, the first relative positional relationship between the first examination position element and the first clock image, after the rotation of the first examination position element, can be such that the positional relationship between the rotated first examination position element and the first clock image corresponds to the relative positional relationship of the target examination position. For example, if the target examination position is the second examination position, then the positional relationship between the rotated first examination position element and the first clock image is the second relative positional relationship. In this embodiment, after the first examination position element is rotated, the first lesion location marker needs to be rotated by a corresponding rotation angle based on the center of the first clock image, so that the actual body orientation of the lesion represented by the rotated first examination position element and the rotated first lesion location marker remains unchanged. Therefore, the target lesion location marker map can be obtained from the rotated first examination position element, the rotated first lesion location marker, and the first clock image.

[0114] In some embodiments, if the user's operation on the examination position function key group is to rotate the first examination position element, the processor will rotate the first lesion position mark based on the center of the first clock image in sync with the first examination position element. Thus, the target lesion position mark map can also be obtained from the rotated first examination position element, the rotated first lesion position mark, and the first clock image.

[0115] In some embodiments, the processor obtains the mapping relationship between the first examination position and the target examination position, and rotates the first lesion location marker and the first examination position element based on the center of the first clock image according to the mapping relationship. Similarly, the target lesion location marker image can be obtained from the rotated first examination position element, the rotated first lesion location marker and the first clock image.

[0116] In the above embodiments, the processor outputs a target lesion location marker map. After the surgeon obtains the target lesion location marker map, the examination position represented by the map matches the patient's position during surgery. Therefore, the actual orientation of the lesion on the patient's body can be intuitively determined through the target lesion location marker map without requiring a change in examination position or a "position + hour" correspondence. This facilitates the surgeon's rapid lesion location determination, improving efficiency and user experience. Furthermore, the target lesion location marker map can be selected for different examination positions based on the user's needs.
