Description

Technical Field

[0001] The embodiments of the present application relate to the field of medical equipment technology, and in particular, to a medical imaging system and a control method thereof. Background Art

[0002] The medical imaging system can obtain the internal tissue image of the object to be detected in a non-invasive manner. For example, the scanning device of the medical imaging system can scan a predetermined part of the object to be detected to obtain imaging data containing information of the predetermined part.

[0003] Common medical imaging systems include, for example, ultrasound imaging systems, magnetic resonance imaging (MRI) systems, and computed tomography (CT) scanning systems.

[0004] It should be noted that the above introduction to the technical background is only intended to provide a clear and complete description of the technical solution of the present application and to facilitate understanding by those skilled in the art. Summary of the invention

[0005] When using the scanning device of the medical imaging system to scan the predetermined part of the object to be detected, the operator needs to perform complex operations on the device and needs to adjust the relative position relationship between the scanning device and the object to be detected and / or the posture of the scanning device to obtain a good imaging effect. Take ultrasonic imaging as an example. When the operator adjusts the scanning device (for example, the probe), the operator needs to focus on the real-time ultrasonic image on the screen and the scanning device on the surface of the object to be detected at the same time. The posture that needs to be adjusted for the scanning device is determined by the real-time ultrasonic image.

[0006] The inventor of this application found that when the operator operates the scanning device such as the probe, the position, posture, scanning results and other contents of the scanning device need to be manually judged, and the corresponding relationship between the ultrasonic image representing the internal information of the object to be detected and the position of the scanning device is not clear, which makes the scanning process complicated and time-consuming, affecting the efficiency and accuracy of the scanning. Such problems are particularly prominent in complex scanning scenarios.

[0007] In order to solve at least one of the above technical problems or similar technical problems, the embodiments of the present application provide a medical imaging system and a control method thereof. In the medical imaging system, an indicating device on a scanning device can project a light beam to a predetermined surface to form a pattern corresponding to the result of analyzing the medical image, and the pattern can indicate how the operator moves the scanning device and / or indicates the inspection result, thereby simplifying the scanning process and improving the efficiency and accuracy of the scanning.

[0008] According to one aspect of an embodiment of the present application, a medical imaging system is provided, the medical imaging system comprising:

[0009] A scanning device, which is used to scan a predetermined part of the object to be detected to obtain imaging data containing information of the predetermined part;

[0010] an indicating device, which is disposed on the scanning device; and

[0011] A control device analyzes the medical image generated based on the imaging data, and controls the indicating device to project a light beam to a predetermined surface according to the analysis result, so as to form a pattern on the predetermined surface.

[0012] According to another aspect of an embodiment of the present application, a control method for a medical imaging system is provided, the medical imaging system comprising:

[0013] A scanning device, which is used to scan a predetermined part of the object to be detected to obtain imaging data containing information of the predetermined part;

[0014] an indicating device, which is disposed on the scanning device; and

[0016] The control method comprises:

[0017] The control device analyzes the medical image generated based on the imaging data, and controls the indicating device to project a light beam onto a predetermined surface according to the analysis result, so as to form a pattern on the predetermined surface.

[0018] One of the beneficial effects of the embodiments of the present application is that the indicating device on the scanning device can project a light beam onto a predetermined surface to form a pattern corresponding to the result of the analysis of the medical image, and the pattern can indicate the operator how to move the scanning device and / or indicate the inspection results. Therefore, the operator does not need to make complex judgments on operations such as translation and rotation of the scanning device and / or the inspection results, and the scanning process is simplified, thereby improving the efficiency of the scanning; in addition, the operator can increase the number of scanned parts per unit time, thereby improving the accuracy of the scanning.

[0034] Example

[0035] An embodiment of the present application provides a medical imaging system. Figure 1 Schematic diagram of a medical imaging system according to an embodiment of the present application. Figure 1 As shown, the medical imaging system 100 includes: a scanning device 1 , an indication device 2 and a control device 3 .

[0036] The scanning device 1 can be used to scan a predetermined part of the object to be detected to obtain imaging data containing information of the predetermined part; the indicating device 2 can be set on the scanning device 1; the control device 3 analyzes the medical image generated based on the imaging data, and controls the indicating device 2 to project a light beam onto the predetermined surface according to the analysis result to form a pattern 21 on the predetermined surface 2.

[0037] In the present application, the pattern 21 formed based on the analysis results of the medical image can instruct the operator how to move the scanning device and / or indicate the inspection results. Therefore, the operator does not need to observe the ultrasound image and combine his own experience to make complex judgments on the operations such as translation and rotation of the scanning device and / or the inspection results. He only needs to pay attention to the pattern near the probe to know how to operate the probe. On the one hand, the line of sight does not need to be distracted by the display, and on the other hand, the movement instructions are more intuitive. Therefore, the scanning process is simplified, thereby improving the efficiency of the scanning; in addition, the operator can increase the number of scanned parts per unit time, thereby improving the accuracy of the scanning.

[0038] In the present application, the medical imaging system 100 is, for example, an ultrasound imaging system, a magnetic resonance imaging (MRI) system, a computer tomography (CT) scanning system, etc. In the following description of the present application, the medical imaging system 100 is an ultrasound imaging system as an example for description, but the contents of these descriptions are not limited to the ultrasound imaging system, and can also be applied to other types of medical imaging systems.

[0039] In the medical imaging system 100 as an ultrasonic imaging system, the scanning device 1 includes, for example, a probe, and the scanning device 1 can transmit ultrasonic waves to a predetermined part of the object to be detected, and receive echoes of the ultrasonic waves, thereby obtaining imaging data. The imaging data can be used to generate a medical image, and the medical image currently scanned and obtained refers to a medical image (anatomical image of a specific section) that can reflect the state (morphology) of the predetermined part of the object to be detected (for example, blood vessels, organs or tissues such as the heart) at the current time (real time).

[0040] Figure 2 is a schematic diagram of the scanning device 1 of the present application. Figure 2 As shown, the indicating device 2 can be arranged on the scanning device 1. In at least one example, as Figure 2 As shown in (A), the indicating device 2 can be integrated on the scanning device 1; in at least another example, as Figure 2 As shown in (B), the indicating device 2 can be installed on the scanning device 1 through the connecting component 4. For example, the connecting component 4 can be mounted on the housing of the scanning device 1, and the indicating device 2 is installed on the connecting component 4. Thus, the indicating device 2 is set on the scanning device 1. In addition, the connecting component 4 can be removed from the scanning device 1, so that the indicating device 2 is separated from the connecting component 4.

[0041] In some embodiments, the indicating device 2 may be a dot matrix of light emitting elements, such as a dot matrix of light emitting diodes. Thus, the indicating device 2 can form a desired pattern on a predetermined surface.

[0042] exist Figure 2In the embodiment, the number of the indicating devices 2 is 3, wherein 1 indicating device 2 is arranged on one side (e.g., the left side) in the length direction of the scanning device 1, 1 indicating device 2 is arranged on the other side (e.g., the right side) in the length direction of the scanning device 1, and 1 indicating device 2 is arranged on one side (e.g., the front side) in the width direction of the scanning device 1. The present application may not be limited thereto, for example, the 3 indicating devices 2 may also be arranged at other positions of the scanning device 1; the number of the indicating devices 2 is not limited to 3, for example, it may be 1 or 2 or more than 3, etc.

[0043] In the present application, the indicating device 2 projects a light beam onto a predetermined surface, and the predetermined surface may be the surface of an object to be detected. For example, the object to be detected is a human body or other animal body, and the surface of the object to be detected may be the skin surface of a human body or other animal body. Since the scanning device 1 is usually moved on the surface of the object to be detected, such a setting can make the indicating effect of the light beam projected by the indicating device 2 more intuitive. That is, the projected pattern can directly represent the moving direction and / or position of the target, and therefore, the intuitiveness and efficiency of the indication are further improved.

[0044] like Figure 2 As shown, the scanning device 1 has a button 1A. The operator of the scanning device 1 can press the button 1A or release the button 1A, thereby generating a signal corresponding to the pressing or releasing. The control device 3 can detect the signal corresponding to the pressing or releasing, thereby performing corresponding processing.

[0045] The control device 3 can communicate with the scanning device 1 and the indicating device 2 in a wired or wireless manner, thereby being able to analyze the medical image generated based on the imaging data and control the indicating device 2 to generate a pattern based on the analysis result; in addition, it can also detect the signal corresponding to pressing or releasing the button 1A, and perform corresponding processing.

[0046] As described above in the present application, in complex scanning scenarios, the implementation of the present application will have a more obvious effect on improving the scanning efficiency. Below, the present application is explained in conjunction with a specific use scenario of the medical imaging system 100.

[0047] The inventors have found that when using an ultrasound imaging system to perform a lower extremity deep vein thrombosis (LDVT) examination, an operator (e.g., a doctor) needs to use a probe to perform a transverse scan and compression test on the lower extremity deep veins every 2 to 3 cm, and sometimes needs to rotate the probe to obtain a high-quality cross-sectional image of the vein; in addition, when the operator adjusts the probe with one hand, he sometimes needs to use the other hand to perform other operations such as parameter adjustment.

[0048] Figure 3 is a schematic diagram of this scenario. Figure 3 As shown, in this scenario, a scanning device 1 is used to scan a predetermined portion 11 of an object to be detected 10 , wherein the object to be detected 10 may be a human body or other animal body, and the predetermined portion 11 may be a blood vessel of the object to be detected, for example, LDVT.

[0049] like Figure 3 As shown, the operator can move the scanning device 1 to different positions of the detection object 10, such as position 111, position 112, position 113, etc., and scan at each position to obtain imaging data containing information of a predetermined part. The imaging data can be used to generate a medical image.

[0050] In the present application, the control device 3 can analyze the above-mentioned medical image, and the analysis includes analyzing the difference between the image of the predetermined part in the medical image and the target. The control device 3 can make the pattern of the light beam projected by the indicating device 2 indicate the target movement information of the scanning device 1 according to the analysis result, and when the operator moves the scanning device 1 according to the target movement information, the difference can be reduced.

[0051] In some embodiments, the difference includes an offset of the image of the predetermined part 11 relative to the center position of the medical image, and the target movement information includes first target translation information for reducing the offset. The first target translation information includes at least a first target translation direction of the scanning device 1; in addition, the first target translation information may also include a movement distance of the scanning device 1 in the first target translation direction.

[0052] Figure 4 It is a schematic diagram of a pattern indicating the translation information of the first target.

[0053] like Figure 4 As shown in (A), when the scanning device 1 is at the current position, the image 401 of the predetermined part 11 is offset to the left relative to the center position O (for example, the horizontal center position) of the medical image 400. Therefore, the control device 3 controls the indicating device 2 to project a light beam on the skin of the object to be detected 10 to form a pattern 402, thereby indicating that the scanning device 1 is moved to the left (that is, the first target translation direction of the scanning device 1). The pattern can be a leftward arrow.

[0054] In addition, the control device 3 can also calculate the distance that the scanning device 1 moves to the left (i.e., the moving distance in the translational direction of the first target) based on the mapping relationship between the translational distance of the scanning device 1 and the moving distance of the image 401 of the predetermined part 11 in the medical image 400, and set the length of the pattern 402 according to the distance (for example, the length of the pattern 402 is equal to the distance), thereby enabling the pattern 402 to indicate the moving distance in the translational direction of the first target.

[0055] exist Figure 4 In the case shown in (A), the operator moves the scanning device 1 according to the instruction of the pattern 402 so that the image 401 of the predetermined part 11 is located in the horizontal center of the medical image 400 (such as Figure 4 As shown in (C), a high-quality image 401 can be obtained.

[0056] like Figure 4 As shown in (B), when the scanning device 1 is at the current position, the image 401 of the predetermined part 11 is offset to the right relative to the center position O (for example, the horizontal center position) of the medical image 400. Therefore, the control device 3 controls the indicating device 2 to project a light beam on the skin of the object to be detected 10 to form a pattern 402, thereby indicating that the scanning device 1 is moved to the right (that is, the first target translation direction of the scanning device 1). The pattern can be a rightward arrow.

[0057] In addition, the control device 3 can also calculate the distance that the scanning device 1 moves to the right (i.e., the moving distance in the translational direction of the first target) based on the mapping relationship between the translational distance of the scanning device 1 and the moving distance of the image 401 of the predetermined part 11 in the medical image 400, and set the length of the pattern 402 according to the distance (for example, the length of the pattern 403 is equal to the distance), thereby enabling the pattern 402 to indicate the moving distance in the translational direction of the first target.

[0058] exist Figure 4 In the case shown in (B), the operator moves the scanning device 1 according to the instruction of the pattern 402 so that the image 401 of the predetermined part 11 is located in the horizontal center of the medical image 400 (such as Figure 4 As shown in (C), a high-quality image 401 can be obtained.

[0059] In some embodiments, the difference includes a difference between a first size of the image of the predetermined part 11 in the first direction and a second size in the second direction and a second threshold, and the target movement information includes second target rotation information for reducing the difference. The second target rotation information at least includes a second target rotation direction of the scanning device 1, such as clockwise rotation or counterclockwise rotation, etc.; in addition, the second target rotation information may also include a rotation angle or rotation position of the scanning device 1 in the second target rotation direction.

[0060] The first direction is, for example, the lateral or horizontal direction of the medical image, and the second direction is, for example, the longitudinal or vertical direction of the medical image. In addition, the present application is not limited thereto, and the first direction may also be, for example, a direction that forms a first angle (for example, the first angle is not equal to 0 degrees, 90 degrees, etc.) with the lateral or horizontal direction of the medical image, and the second direction may also be, for example, a direction that forms a second angle (for example, the second angle is not equal to 0 degrees, 90 degrees, etc.) with the longitudinal or vertical direction of the medical image.

[0061] The size difference between the first size and the second size can be expressed as, for example, a ratio of the first size to the second size, or a difference between the first size and the second size.

[0062] The difference between the size difference and the second threshold value may be, for example, an absolute value of the difference between the size difference and the second threshold value, or a ratio of the size difference to the second threshold value.

[0063] The above parameters such as difference value / threshold value can be predefined by the operator according to the different objects to be detected, or can be automatically determined by the medical imaging system.

[0064] Figure 5 It is a schematic diagram of the pattern indicating the rotation information of the second target. Figure 6 Schematic diagram of the posture of the scanning device 1 relative to the predetermined part 11.

[0065] like Figure 5 As shown in (A), when the scanning device 1 is at the current position, the ratio of the first size L1 of the image 501 of the predetermined part 11 in the first direction (e.g., horizontal direction) to the second size L2 in the second direction (e.g., vertical direction) is L1 / L2, and L1 / L2 is greater than the second threshold value (e.g., the second threshold value is 1). Therefore, the control device 3 controls the indicating device 2 to project a light beam on the skin of the object to be detected 10 to form a pattern 502, thereby indicating that the scanning device 1 is rotated in the clockwise direction (i.e., the second target rotation direction of the scanning device 1). The pattern can be an arrow pointing in the clockwise direction.

[0066] In addition, the control device 3 can also calculate the rotation angle or rotation position of the scanning device 1 in the clockwise direction (i.e., the rotation angle or rotation position in the second target rotation direction) based on the mapping relationship between the rotation angle of the scanning device 1 and L1 / L2 in the image 501 of the predetermined part 11, and set the length of the pattern 502 according to the rotation angle or rotation position (for example, the central angle of the length of the pattern 502 corresponding to the rotation angle).

[0067] Figure 5 (A) corresponds to Figure 6 The longitudinal direction of the scanning device 1 shown in (A) is not perpendicular to the extension direction of the predetermined part 11 (for example, the extension direction of the blood vessel). Figure 6 As shown in (A), the pattern 502 is an arrow pointing in the clockwise direction, thereby guiding the operator to rotate the scanning device 1 so that the length direction of the scanning device 1 is perpendicular to the extension direction of the predetermined part 11 (for example, the extension direction of the blood vessel).

[0068] exist Figure 5 In the case shown in (B), the operator moves (eg, rotates) the scanning device 1 according to the instruction of the pattern 502, so that the L1 / L2 of the image 501 of the predetermined part 11 reaches the second threshold value (eg, Figure 5 As shown in (B), a high-quality image 501 can be obtained.

[0069] Figure 5 (B) corresponds to Figure 6 In (B), the operator rotates the scanning device 1 according to the instruction of the pattern 502, so that the length direction of the scanning device 1 is perpendicular to the extension direction of the predetermined part 11 (for example, the extension direction of the blood vessel).

[0070] In the present application, the control device 3 can perform real-time analysis while the scanning device 1 is moving (eg, translating and / or rotating), and control the indicating device 2 to form a real-time pattern according to the real-time analysis result.

[0071] For example, when the operator is moving the scanning device 1 (for example, moving the scanning device 1 horizontally), if the offset of the image 401 relative to the center position O of the medical image 400 becomes larger and larger, the length of the pattern 402 will increase accordingly; if the offset of the image 401 relative to the center position O of the medical image 400 becomes smaller and smaller, the length of the pattern 402 will decrease accordingly until the pattern 402 disappears; for another example, when the operator is moving the scanning device 1 (for example, moving the scanning device horizontally), if the difference between L1 / L2 of the image 501 and the second threshold value becomes larger and larger, the length of the pattern 502 will increase accordingly; if the difference between L1 / L2 of the image 501 and the second threshold value becomes smaller and smaller, the length of the pattern 502 will decrease accordingly until the pattern 502 disappears.

[0072] In the present application, the analysis of the medical image by the control device 3 may also include: detecting the medical image. The control device 3 may make the pattern of the light beam projected by the indicating device 2 indicate the detection result according to the detection result of the medical image, so that the operator can easily confirm and identify the detection result.

[0073] In the case where the predetermined part 11 is a blood vessel, the detection of the medical image can be an analysis of the health condition of the blood vessel, and the pattern can indicate the health condition as a detection result.

[0074] For example, when the detection result is the first result, the pattern is the first pattern, and when the detection result is the second result, the pattern is the second pattern, and at least one of the shape, color, and position of the first pattern and the second pattern is different. In a specific example, if the analysis of the health status of the blood vessel is that the blood vessel is healthy (for example, there is no thrombus in the blood vessel), the pattern is a green dot, and if the analysis of the health status of the blood vessel is that the blood vessel is unhealthy (for example, there is a thrombus in the blood vessel), the pattern is a red dot, etc.

[0075] In the present application, the control device 3 may detect the medical image by performing one or a combination of two or more of the following: detection based on color blood flow pattern images, detection based on Doppler pattern images, detection based on B-mode images, and detection based on elastic imaging.

[0076] Detection based on color blood flow mode images, for example, includes: using a segmentation model (e.g., a deep learning model) to obtain a bounding box of a blood vessel (e.g., a vein), where the bounding box is the ROI of the color flow mode image; in the color flow mode, using the segmentation model to obtain the area of ​​the vein and the area of ​​the color blood flow part, if the area of ​​the color blood flow part is very small or completely absent relative to the area of ​​the vein, it indicates that there may be a thrombus at the detection location.

[0077] The detection based on the Doppler mode image includes, for example: in the Doppler mode, if the blood flow velocity decreases significantly, it indicates that there may be a thrombus at the detection position.

[0078] Detection based on elastic imaging includes, for example: obtaining the vein area using a segmentation model (e.g., a deep learning model); obtaining the elasticity value of the vein area and the elasticity value of other parts in the medical image after the operation of pressing the object to be detected using the scanning device 1 is completed based on elastic imaging technology. If the elasticity value of the vein area and the elasticity value of other parts are too small, it means that the vein cannot contract and there may be a thrombus at the detection position.

[0079] In the above manner, the pattern can give the operator an intuitive prompt, thereby minimizing the operator's attention from being diverted from the scanning device 1, and further improving the scanning efficiency. The prompt effect of the pattern can actually be understood as corresponding to the obvious change of the detection result in the ultrasound image. The specific health status analysis can be determined by the operator by further observing the image as needed.

[0080] The detection based on the B-mode image includes, for example: for the first moment when the operator starts to press the object to be detected using the scanning device 1, and for the second moment when the operator stops pressing the object to be detected using the scanning device 1, the control device 3 can perform detection based on the medical image at the first moment (e.g., the medical image of the B-mode) and the medical image at the second moment (e.g., the medical image of the B-mode). In at least one specific example, the control device 3 can use a segmentation model (e.g., a deep learning model) to obtain a first bounding box of the vein in the medical image at the first moment, and use a segmentation model (e.g., a deep learning model) to obtain a second bounding box of the vein in the medical image at the second moment. If the difference between the height of the first bounding box and the height of the second bounding box is less than a threshold, it indicates that the vein cannot be flattened normally, and there may be a thrombus at the detection position. In addition, the detection performed by the control device 3 based on the medical image at the first moment and the medical image at the second moment can also be other types of detection.

[0081] In the present application, the control device 3 can be based on the operator's Figure 2 The first moment and the second moment are determined by the pressing and releasing operations of the key 1A of the scanning device 1 in (A).

[0082] For example, the operator may press the button 1A when starting to press the object to be detected by using the scanning device 1 ; and the operator may release the button 1A when finishing pressing the object to be detected by using the scanning device 1 .

[0083] In some embodiments, the control device 3 can be configured to: determine the moment when the button 1A is pressed as the first moment when the scanning device 1 starts pressing the object 10 to be detected; determine the moment when the button 1A is released as the second moment when the scanning device 1 stops pressing the object 10 to be detected.

[0084] In some embodiments of the present application, the control device 3 may detect the medical image by performing one or a combination of two or more of the following: detection based on color blood flow pattern images, detection based on Doppler pattern images, detection based on B-mode images, and detection based on elastic imaging. For example, when a thrombus is detected in a vein based on any of the above detection methods, the corresponding medical image will be saved and it will be determined that a thrombus is present in the vein.

[0085] The above is an example of the detection method for detecting whether there is a thrombus in a vein, but the present application is not limited thereto, and the above detection may also be based on other purposes and use other detection methods.

[0086] In the present application, after the detection based on the medical image is completed, the control device 3 further controls the indicating device 2 to project a light beam to the predetermined surface to form a moving indicating pattern on the predetermined surface. Thus, the operator can move the scanning device 1 to the next position on the object 10 to be detected according to the moving indicating pattern.

[0087] The movement indication pattern may indicate second target translation information of the scanning device 1, and the second target translation information may include the second target translation direction. In addition, the second target translation information may also include the second target translation distance. For example, the endpoint of the movement indication pattern in the second target translation direction may be used to indicate the target position of the scanning device 1 moving along the second target translation direction.

[0088] For example, the scanning device 1 scans the predetermined part 11 at the position 111 to obtain imaging data, and the control device 3 detects the medical image generated based on the imaging data. After the detection is completed (for example, the detection result is the first result or the second result, etc.), the indication device 2 projects a light beam to the predetermined surface (for example, the skin of the object to be detected 10) to form Figure 3 The moving indication pattern 31 shown, wherein the moving indication pattern 31 can point to the next position (for example, to the right), and the right end point 311 of the moving indication pattern 31 can be the target position of the target position moving in the second target translation direction of the scanning device 1, for example, the position of the right end point 311 of the moving indication pattern 31 is position 112.

[0089] In some embodiments of the present application, when the control device 3 controls the indicating device 2 to project a light beam onto a predetermined surface to form a pattern on the predetermined surface, the control device 3 can also control the sound generating device (not shown) to emit a prompt sound corresponding to the pattern, and the prompt sound can be a voice or a sound of predetermined content. Thus, the operator can be instructed by both the pattern and the prompt sound, thereby improving reliability and convenience.

[0090] For example, in generating Figure 4 When the pattern 402 shown in FIG. 1 is generated, the sound generating device emits a prompt sound corresponding to the translation information of the first target; and / or Figure 5 When the first pattern or the second pattern is generated based on the detection result, the sound device emits a prompt sound corresponding to the first pattern or the second pattern; and / or, when the first pattern or the second pattern is generated based on the detection result, the sound device emits a prompt sound corresponding to the first pattern or the second pattern; and / or, when the first pattern or the second pattern is generated Figure 3 When the moving indication pattern 31 is shown, the sound emitting device emits a prompt sound corresponding to the moving indication pattern 31.

[0091] In some embodiments of the present application, the control device 3 can adjust the position of the imaging data acquired by the scanning device 1 corresponding to the object to be detected 10 according to the offset of the image of the predetermined part 10 relative to the center of the image in the second direction to reduce the offset. In this way, the scanning position of the scanning device 1 can be automatically adjusted to improve the accuracy of the detection. The second direction is, for example, the longitudinal or vertical direction of the medical image.

[0092] Figure 7 It is a schematic diagram of adjusting the scanning position of the scanning device 1.

[0093] like Figure 7 As shown in (A), when the scanning device 1 is at the current position, the predetermined part 11 is scanned to obtain imaging data, and a medical image 700 is obtained based on the imaging data. The control device 3 can process the medical image 700 to identify the image 701 of the predetermined part 11. For example, the control device 3 uses a deep learning segmentation model to process the medical image 700.

[0094] like Figure 7As shown in (A), the image 701 of the predetermined part 11 is offset downward relative to the center position O1 (for example, the center position in the longitudinal direction) of the medical image 700. Therefore, the control device 3 controls to adjust the imaging data acquired by the scanning device 1 corresponding to the position in the object to be detected 10, thereby adjusting the position of the image 701 of the predetermined part 11 in the second direction (for example, the longitudinal direction) of the medical image 700. For example, when the scanning device 1 is an ultrasonic probe, the control device 3 adjusts the depth of ultrasonic emission and / or the depth of ultrasonic reception of the scanning device 1. Specifically, the control device 3 can adjust the depth of ultrasonic emission and / or the depth of ultrasonic reception of the scanning device 1 downward.

[0095] like Figure 7 As shown in (B), after adjustment, the image 701 of the predetermined part 11 moves upward in the second direction (eg, longitudinal direction) of the medical image 700 and approaches the center position O1 of the medical image 700 in the second direction.

[0096] In the present application, the imaging data acquired by the scanning device 1 is adjusted to correspond to the position in the object to be detected 10, which not only makes the image 701 of the predetermined part 11 easier to observe, but also, when the operation of pressing the object to be detected is performed, the image 701 of the predetermined part 11 (for example, a blood vessel) after pressing can still be located inside the medical image 700, thereby avoiding the image 701 of the predetermined part 11 being located outside the medical image 700, so that the detection result can be improved.

[0097] In this application, if Figure 1 The illustrated medical imaging system 100 includes suitable hardware, software, or a combination thereof for supporting medical imaging (i.e., enabling data to be obtained for generating and / or rendering images during a medical imaging examination). For example, the medical imaging system 100 may be an ultrasound imaging system or a magnetic resonance system configured to generate and / or render ultrasound images, etc.

[0098] like Figure 1 As shown, the medical imaging system 100 may also include a display 114 .

[0099] The display 114 may be configured to display an image (e.g., via a screen). In some cases, the display 114 may also be configured to generate, at least in part, the displayed image. In addition, the display 114 may also support user input / output. For example, in addition to the image, the display 114 may also provide (e.g., via a screen) user feedback (e.g., information related to the system, its functions, its settings, etc.). The display 114 may also support user input (e.g., via user controls 118), such as to allow control of medical imaging. The user input may involve controlling the display of an image, selecting settings, specifying user preferences, requesting feedback, etc.

[0100] In some embodiments, the medical imaging system 100 may also incorporate additional and dedicated computing resources, such as one or more computing systems 120. In this regard, each computing system 120 may include appropriate circuitry, interfaces, logic, and / or code for processing, storing, and / or communicating data. The computing system 120 may be a dedicated device configured for use specifically in conjunction with medical imaging, or it may be a general-purpose computing system (e.g., a personal computer, a server, etc.) that is configured and / or configured to perform the operations described below with respect to the computing system 120. The computing system 120 may be configured to support the operation of the medical imaging system 100, as described below. In this regard, various functions and / or operations may be offloaded from the imaging system. Doing so may simplify and / or centralize certain aspects of processing to reduce costs (by eliminating the need to increase processing resources in the imaging system).

[0101] The computing system 120 can be configured and / or arranged for use in different ways. For example, in some implementations, a single computing system 120 can be used; in other implementations, multiple computing systems 120 are configured to work together (e.g., based on a distributed processing configuration), or work separately, where each computing system 120 is configured to handle specific aspects and / or functions, and / or process data only for a specific medical imaging system 100.

[0102] In some embodiments, the computing system 120 may be local (e.g., co-located with one or more medical imaging systems 100, such as within the same facility and / or the same local network); in other implementations, the computing system 120 may be remote and thus accessible only via a remote connection (e.g., via the Internet or other available remote access technology). In certain implementations, the computing system 120 may be configured in a cloud-based manner and may be accessed and / or used in a manner substantially similar to accessing and using other cloud-based systems.

[0103] Once the data is generated and / or configured in the computing system 120, the data can be copied and / or loaded into the medical imaging system 100. This can be done in different ways. For example, the data can be loaded via a directional connection or link between the medical imaging system 100 and the computing system 120. In this regard, the communication between the different elements in the setting can be performed using available wired and / or wireless connections and / or according to any suitable communication (and / or networking) standards or protocols. Alternatively or additionally, the data can be loaded into the medical imaging system 100 indirectly. For example, the data can be stored in a suitable machine-readable medium (e.g., a flash memory card, etc.), and then the machine-readable medium is used to load the data into the medical imaging system 100 (on-site, such as by a user of the system (e.g., an imaging clinician) or authorized personnel); or the data can be downloaded to a local electronic device capable of communication (e.g., a laptop, etc.), and then the electronic device is used on-site (e.g., by a user of the system or authorized personnel) to upload the data to the medical imaging system 100 via a direct connection (e.g., a USB connector, etc.).

[0104] In operation, the medical imaging system 100 can be used to generate and present (e.g., render or display) images during a medical examination, and / or to support user input / output in conjunction therewith. The images can be 2D, 3D, and / or 4D images. The specific operations or functions performed in the medical imaging system 100 to facilitate the generation and / or presentation of the images depend on the type of system (i.e., the manner in which the data corresponding to the images is obtained and / or generated). For example, in ultrasound imaging, the data is based on the transmitted ultrasound signal and the echo ultrasound signal 0.

According to some embodiments, the receiver 218, the plurality of A / D converters 222, the RF processor 224, and the beamformer 220 may be integrated into a single beamformer, which may be digital. In various embodiments, the ultrasound imaging system 200 includes a plurality of receive beamformers 220.

[0113] The user input device 230 may be used to input patient data, scan parameters, settings, select protocols and / or templates, interact with the artificial intelligence segmentation processor to select tracking targets, etc. In an exemplary embodiment, the user input device 230 is operable to configure, manage, and / or control the operation of one or more components and / or modules in the ultrasound imaging system 200.

In an exemplary embodiment, the signal processor 240 is operable to perform display processing and / or control processing, etc. The acquired ultrasound scan data may be processed in real time during a scanning session as echo signals are received. Additionally or alternatively, the ultrasound scan data may be temporarily stored in the RF / IQ buffer 226 during the scanning session and processed in a less real-time manner in an online or offline operation. In various embodiments, the processed image data may be presented at the display system 260 and / or may be stored at the archive 270.

[0117] The ultrasound imaging system 200 is operable to continuously acquire ultrasound scan data at a frame rate suitable for the imaging situation under consideration. Typical frame rates are in the range of 20 to 220, but may be lower or higher. The acquired ultrasound scan data may be displayed in real time on the display system 260 at the same, or slower or faster display rate as the frame rate. An image buffer 250 is included for storing processed frames of acquired ultrasound scan data that are not scheduled for immediate display.
