Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of image scanning, and particularly relates to a scanning control method, system and device of a medical scanning device and an electronic device. BACKGROUND

[0002] In medical scanning, a medical scanning device is usually used to scan a to-be-scanned object. For example, the medical scanning device can be a computed tomography (CT) device. In an actual scanning process, the medical scanning device usually needs to be scanned along a desired scanning direction of the to-be-scanned object, so as to obtain a high-quality scanning image.

[0003] At present, in order to obtain a high-quality scanning image, the medical scanning device usually needs to be tilted at a certain angle along the desired scanning direction, or a medical staff needs to actively adjust the position of the to-be-scanned object to an ideal position.

[0004] However, the medical scanning device has a complex structure and is relatively large, and usually needs a long time to be physically tilted at an angle and a long time to be restored to an initial position. Therefore, the examination time is increased, and the efficiency of the department examination is affected. In addition, when the medical staff actively adjusts the position of the to-be-scanned object, the to-be-scanned object needs to be scanned and the obtained scanning image needs to be previewed after each adjustment, until the position of the to-be-scanned object is the ideal position, and a high-quality scanning image is obtained. At this time, the examination time is also increased due to multiple positions, and the examination efficiency is affected. SUMMARY

[0005] The present application provides a scanning control method, system and device of a medical scanning device and an electronic device, which can solve the problem that the examination time required for scanning is long and the efficiency is low in the prior art.

[0006] In a first aspect, the present application provides a scanning control method of a medical scanning device, which comprises the following steps:

[0007] According to the positioning image of a target part of a to-be-scanned object, a first angle between a target scanning baseline in the target part and a scanning direction of the medical scanning device is determined. The target scanning baseline is used to describe a desired scanning direction when the target part is scanned by the medical scanning device.

[0008] The adjustable device is controlled to move the target part based on the first angle. A second angle between the target scanning baseline of the moved target part and the scanning direction is less than the first angle.

[0009] The medical scanning device is controlled to scan the moved target part.

[0018] determining the first angle as the third angle; or,

[0019] determining a target tilt angle corresponding to the first angle according to a preset mapping relationship between tilt angles and the first angle, and determining the target tilt angle as the third angle.

[0020] In an embodiment, the adjustable device is controlled to move the target part based on the first angle, comprising:

[0021] controlling the adjustable device to move the target part until the target scan baseline is parallel to the scan direction.

[0022] In an embodiment, the target part at least includes a head part, and the adjustable device at least includes a headrest for controlling the movement of the head part.

[0023] In an embodiment, before the first angle between the target scan baseline in the target part and the scan direction of the medical scanning device is determined according to a positioning image of the target part of the object to be scanned, the method further comprises:

[0024] determining a preset scan baseline set in a scan protocol of the medical scanning device as the target scan baseline.

[0025] In a second aspect, the embodiments of the present application provide a scanning control device of a medical scanning device, comprising:

[0026] The first determining module is configured to determine, according to a positioning image of a target part of a to-be-scanned object, a first angle between a target scanning baseline in the target part and a scanning direction of the medical scanning device, the target scanning baseline being used to describe an expected scanning direction of the target part when the target part is scanned by the medical scanning device.

[0027] The first control module is configured to control the adjustable device to move the target part based on the first angle, a second angle between the target scanning baseline of the moved target part and the scanning direction being less than the first angle.

[0028] The second control module is configured to control the medical scanning device to scan the moved target part.

[0029] In a third aspect, an electronic device is provided, which includes a memory, a processor, and a computer program stored in the memory and capable of running on the processor, and the processor implements the method of the first aspect when executing the computer program.

[0030] In a fourth aspect, a computer readable storage medium is provided, which stores a computer program, and the computer program is executed by a processor to implement the method of the first aspect.

[0031] In a fifth aspect, a computer program product is provided, which, when running on an electronic device, causes the electronic device to execute the method of the first aspect.

[0032] In a sixth aspect, a medical system is provided, which includes a medical scanning device, a scanning bed, and an adjustable device.

[0033] The adjustable device is arranged on the scanning bed, and the medical scanning device is connected with the adjustable device.

[0034] The medical scanning device is configured to scan a target part of a to-be-scanned object located on the scanning bed and send a first angle to the adjustable device, the first angle being used to describe an angle between a target scanning baseline in the target part and a scanning direction of the medical scanning device, the target scanning baseline being used to describe an expected scanning direction of the target part when the target part is scanned by the medical scanning device.

[0035] The adjustable device is configured to receive the first angle and control the target part to move.

[0036] The beneficial effects of the embodiments of the present application compared with the prior art are: when the target part of the to-be-scanned object is scanned, the first angle between the target scanning baseline in the target part and the scanning direction of the medical scanning device can be determined according to the positioning image capable of describing the position of the target part of the to-be-scanned object. Since the target scanning baseline is used to describe the expected scanning direction when the target part is scanned by the medical scanning device, the first angle can be used to control the adjustable device to move the target part, so that the second angle between the target scanning baseline of the moved target part and the scanning direction is less than the first angle. That is, the scanning direction of the medical scanning device is closer to the expected scanning direction, so as to improve the image quality generated when the medical scanning device scans the moved target part. Based on this, by moving the target part through the adjustable device which can be conveniently controlled, the angle between the target scanning baseline and the scanning direction can be adjusted, so that when the positioning of the to-be-scanned object is not ideal, the positioning of the to-be-scanned object does not need to be actively adjusted, and the medical scanning device does not need to be physically inclined. Further, the examination time can be reduced and the examination efficiency can be improved on the basis of ensuring the image quality of the final scanning image. BRIEF DESCRIPTION OF DRAWINGS

[0046] In the following description, for the purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0047] It should be understood that the term "comprising" when used in this specification and the appended claims, specifies the presence of stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0048] It should be noted that the information collection process (such as the scanning process of the object to be scanned) / feature extraction process involved in the present application is performed with the user's knowledge and permission, i.e., the information collection process / feature extraction process meets the legal and regulatory requirements and does not belong to the act of harming public interests.

[0049] In addition, in the description of the present application and the appended claims, the terms "first", "second", "third", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0050] In medical scanning, the object to be scanned is usually scanned by a medical scanning device. For example, the medical scanning device can be CT, Positron Emission Tomography CT (PET-CT), etc., which is not limited. And in the actual scanning process, the medical scanning device usually needs to scan along the desired scanning direction of the object to be scanned to obtain a high-quality scanning image.

[0051] At present, in order to obtain a high-quality scanning image, the medical scanning device usually needs to be tilted at a certain angle along the desired scanning direction before scanning, or the medical staff needs to actively adjust the positioning of the object to be scanned to the ideal positioning.

[0052] However, the medical scanning device is structurally complex and large, and usually needs a long time for physical angular tilting and a long time for recovery to the initial position. Therefore, the examination time will be increased, and the efficiency of the department examination will be affected.

[0053] For example, referring to Figure 1 , Figure 1 is a schematic diagram of an application scenario in the prior art for scanning a to-be-scanned object. Taking a CT device as an example of the medical scanning device, and taking the need to scan the head of the to-be-scanned object as an example for explanation. In head CT scanning, in order to obtain a clear basal ganglia layer image, a suitable target scanning baseline (i.e., the desired scanning direction when the head is scanned) is usually selected according to the specific circumstances of the to-be-scanned object. In CT head scanning, common target scanning baselines include but are not limited to the auriculo-temporal line, the auriculo-superciliary line, and the auriculo-orbital line. This example takes the auriculo-temporal line as an example for illustration.

[0054] For example, referring to Figure 1 , the to-be-scanned object needs to lie on a scanning bed, and the head is located in a gantry in the medical scanning device. When the gantry scans the head, the head needs to be scanned along the auriculo-temporal line. At this time, the gantry usually needs to be tilted by 15°. For example, the tilt in the right edge of the figure corresponds to the arrow of tilting. Wherein, tilt represents the tilting angle of the gantry during scanning. “-” and “+” represent the direction of tilting the gantry. Figure 1

[0055] However, the gantry usually needs 20 seconds to be physically tilted by 15°, and the tilted gantry also needs to be recovered after the examination is completed. That is, it can be considered that the process of physically tilting the gantry to perform a scanning examination at least needs 40 seconds, which greatly affects the examination efficiency.

[0056] In addition, there is a risk of collision when the gantry is physically tilted. For example, when the to-be-scanned object enters the scanning room for examination with devices such as a drip stand and a sickbed, there is a risk of collision between the medical scanning device and the devices such as the drip stand and the sickbed.

[0057] In addition, when the medical staff actively adjusts the positioning of the to-be-scanned object, the to-be-scanned object needs to be scanned and the obtained scanning image needs to be previewed after each adjustment until the positioning of the to-be-scanned object is an ideal positioning and a high-quality scanning image is obtained. At this time, multiple positionings will also increase the examination time, and further affect the examination efficiency.

[0058] Therefore, in order to be able to reduce the examination time and improve the examination efficiency on the basis of obtaining a high-quality scanning image, the embodiments of the present application provide a scanning control method of a medical scanning device, which can be applied to a medical system. For example, it can be applied to the medical scanning device, the controller and other electronic devices in the medical system, and the embodiments of the present application do not make any limitation on the specific type of the electronic device.​

[0059] Referring to Figure 2 , Figure 2 An implementation flowchart of a scanning control method of a medical scanning device is shown, and the method comprises the following steps:

[0060] S201, determining a first angle between a target scanning baseline in the target part and a scanning direction of the medical scanning device according to a positioning image of the target part of the to-be-scanned object.

[0061] In an embodiment, the to-be-scanned object can be a human or an animal, and no limitation is made. However, it should be noted that when the to-be-scanned object is an animal, the animal needs to be in a sleep state for scanning because the animal will not cooperate with the medical staff quietly. In this embodiment, the to-be-scanned object is mainly explained as a human.

[0062] In an embodiment, the positioning image can be considered as image data generated after the medical scanning device scans the target part, which can be used to describe the position of the target part. That is, the spatial position of the target part in the coordinate system corresponding to the medical scanning device. Since the positioning image can describe the position of the target part, the positioning image can also provide a positioning reference for subsequent scanning and reconstruction of the medical scanning device.

[0063] In an embodiment, the target scanning baseline is used to describe the expected scanning direction when the target part is scanned by the medical scanning device. The target scanning baseline can be pre-set in the electronic device. It should be noted that the target scanning baseline can be determined by the electronic device in response to the operation of the medical staff. The target scanning baseline corresponding to different to-be-scanned objects or different target parts to be scanned is usually different.

[0064] In an embodiment, when the medical scanning device does not tilt or move, the scanning direction of the medical scanning device is usually fixed. Based on this, the scanning direction of the medical scanning device can be considered as a fixed direction, which can be pre-stored in the electronic device.

[0065] As an example, the scanning direction can be the direction of the scanning factor emitted by the medical scanning device. The scanning factor is different when the type of the medical scanning device is different. For example, when the medical scanning device is a CT device, the scanning factor can be a ray; when the medical scanning device is an ultrasonic device, the scanning factor can be an ultrasonic wave, and no limitation is made.

[0066] Exemplarily, taking the scanning device as an electron beam CT device, a plurality of target rings and corresponding electron guns are arranged on the gantry. The electron gun is used to emit X-rays and reach the target ring corresponding to the electron gun. At this time, the direction of the electron gun shooting and reaching the target ring is the scanning direction.

[0067] In another embodiment, the scanning direction can also be characterized based on a preset coordinate system of the medical scanning device and stored in the electronic device. Exemplarily, taking the medical scanning device as a CT device, referring to Figure 1 It can be considered that in the preset coordinate system, the vertical direction of the gantry is the XY plane, and the horizontal direction of the scanning bed on which the to-be-scanned object lies is the Z direction (i.e., the moving direction of the scanning bed). At this time, the scanning direction of the medical device can be considered as a direction coinciding with or parallel to the XY plane.

[0068] Since the scout image can describe the position of the target part, it can be considered that the position information of the target scanning baseline in the target part is also known information. Moreover, since the scout image is used to describe the spatial position of the target part in the coordinate system corresponding to the medical scanning device, it can be considered that the scanning direction of the medical scanning device can also be characterized by the coordinate system corresponding to the medical scanning device. Based on this, the electronic device can determine the first angle according to the position information of the target scanning baseline and the position information corresponding to the scanning direction. The first angle can be calculated according to the included angle calculation formula between two line segments, and details are not described herein.

[0069] In another embodiment, the electronic device can also generate a scout frame in the scout image and determine the baseline direction of the target scanning baseline in the scout frame. Then, the angle between the baseline direction and the scanning direction is determined as the first angle.

[0070] The scout frame can be used to determine the range to be scanned by the medical scanning device, so as to subsequently perform scanning and reconstruction. Exemplarily, when scanning the to-be-scanned object, the medical scanning device can not need to scan the whole body of the to-be-scanned object, but can only scan the target part of the to-be-scanned object.

[0071] It can be understood that based on the scout frame limiting the target part to be scanned, the range to be scanned by the medical scanning device can be reduced, and thus the working time of the medical scanning device is reduced.

[0072] In an embodiment, the target part includes but is not limited to the head, the lumbar spine and the like. The specific type of the target part is not limited in the embodiment. The target part can be one or a plurality of target parts.

[0073] In an embodiment, different target scanning baselines pass through different specific human tissues. Therefore, the electronic device can identify the tissue positions of the at least two human tissues passed through by the target scanning baseline. Then, the direction of the line connecting the two tissue positions is determined as the baseline direction.

[0074] In an embodiment, the human tissues passed through by each target scanning baseline can be set in advance. For example, when the target scanning baseline is the brow line, the human tissues passed through can include the eyebrows and the skull base. When the target scanning baseline is the orbitomeatal line, the human tissues passed through can include the eye socket and the skull base. In this embodiment, the human tissues corresponding to each target scanning baseline are not limited.

[0075] In addition, the electronic device can set a human tissue recognition model in advance to perform image model processing on the positioning image to determine the image position corresponding to the human tissue. The human tissue recognition model can be constructed and trained according to a neural network model capable of processing images, and details are not described herein.

[0076] In an embodiment, the electronic device can be provided with a positioning frame generation model trained in advance, which can recognize the positioning image and output a positioning frame. In another embodiment, the electronic device can also generate a positioning frame in the positioning image in response to an information configuration instruction. In this embodiment, the manner of generating the positioning frame is not limited.

[0077] For example, after the positioning image is generated, the electronic device can display an information input configuration box of the positioning frame. At this time, the electronic device can generate an information configuration instruction based on the information input by the medical staff in the information input configuration box and respond to generate a positioning frame in the positioning image.

[0078] For example, after the positioning image is generated, the electronic device can display an information input configuration box of the positioning frame. At this time, the electronic device can generate an information configuration instruction based on the information input by the medical staff in the information input configuration box and respond to generate a positioning frame in the positioning image.

[0079] As an example, refer to FIG. 6. Figure 3 , Figure 3Fig. 1 is a schematic diagram of an application scenario of a positioning frame in a scanning control method of a medical scanning device according to an embodiment of the present application. In the figure, the number 1 in the circle corresponds to "2" in 2Head Axlal, which represents a scanning protocol in the medical scanning device. The numbers 2.1 and 2.2 in the circle correspond to the numbers of a sequence of the positioning frame, and clicking the numbers can select the positioning frame. After the scanning protocol is selected, the electronic device can automatically configure sequence parameters required for multiple scans in response to an information configuration instruction, to obtain a final target scanning protocol. At this time, the medical scanning device can scan a target part based on the parameter information configured in the target scanning protocol. The sequence parameters required for the scanning protocol can refer to the various information corresponding to the information input configuration frame described above, and will not be described here.

[0080] Figure 3 In the figure, the curve protruding upward and to the right is a dose curve (the curve corresponding to the number 3 in the circle), and the more the curve protrudes to the right, the greater the mAs (radiation dose received during the examination). The number "252" displayed at the bottom of the curve represents the average value of the mAs. The number 4 in the circle corresponds to a horizontal grid of the positioning frame, which represents a collimation width. The positioning frame is divided into several regions horizontally according to the collimation width. The electronic device can increase or decrease the number of grids in response to a click operation of a medical staff on a first frame line (for example, a top frame line or a bottom frame line) of the positioning frame. The FOV corresponding to the number 5 in the circle represents the field of view of the medical scanning device, that is, the width of the positioning frame. The electronic device can increase or decrease the FOV in response to a click operation of a medical staff on a second frame line (for example, a left frame line or a right frame line) of the positioning frame. The tilt corresponding to the number 6 in the circle represents the tilt angle required for the medical scanning device to tilt during scanning. For example, tilt 5° to the left or to the right. The electronic device can modify the tilt in response to a click operation of a medical staff. The number 1447.2 corresponding to the number 7 in the circle represents the end position of the scan, and the number 1286.6 corresponding to the number 9 in the circle represents the start position of the scan. The L: 160.6 corresponding to the number 8 in the circle represents the length of the scan. That is, the field of view, the start position, the end position, and the length of the positioning frame are used to limit the range to be scanned by the medical scanning device. The upward arrow corresponding to the number 10 in the circle represents the scanning direction of the medical scanning device. In actual scenarios, the scanning direction can also be downward, and at this time Figure 3 the downward arrow can be displayed in the figure. The electronic device can adjust the direction of the arrow in response to a click operation of a medical staff on the arrow. The number 1094 corresponding to the number 11 in the circle represents the current horizontal bed code value.

[0081] It should be noted that Figure 3The oblique line in the figure can be considered as a target scanning baseline when the medical scanning device is expected to scan, which can be bound with the scanning protocol described above, or determined in response to the information configuration instruction of the medical staff, which is not limited. That is, the electronic device can determine the preset scanning baseline set in the scanning protocol corresponding to the medical scanning device as the target scanning baseline.

[0082] Among them, the target scanning baseline corresponding to different to-be-scanned objects or different target parts to be scanned is usually different. For example, for the same target part, the target scanning baseline corresponding to the to-be-scanned object can be different when the age of the to-be-scanned object is different; and for the same to-be-scanned object, the target scanning baseline corresponding to the to-be-scanned object is usually different when the target part to be scanned by the to-be-scanned object is different.

[0083] As an example, when the target part is the head, in order to obtain a clear basal ganglia layer image, a suitable target scanning baseline is usually selected according to the specific circumstances of the to-be-scanned object. For example, in head scanning, the common scanning baselines described above include the auditory acanthus line, the auditory brow line, and the auditory orbit line. Among them, when the auditory acanthus line is used as the target scanning baseline for CT scanning, the scanning image of the basal ganglia layer can be accurately obtained.

[0084] Specifically, the auditory acanthus line is often used as the preferred target scanning baseline due to its good correspondence with the basal ganglia region. The medical staff can ensure the quality and accuracy of the scanning image by accurately adjusting the scanning parameters (for example, the sequence parameters described above) and the positioning of the to-be-scanned object, thereby providing strong support for clinical diagnosis and treatment.

[0085] In addition, when the auditory brow line is used as the target scanning baseline, the lowest part of the three cranial fossae can be considered, and the fourth ventricle and the basal ganglia region can also have good effects.

[0086] In addition, the auditory orbit line is mainly used for scanning of orbital lesions, but in some cases, by adjusting the scanning direction, the image of the basal ganglia region can also be obtained. Therefore, the auditory orbit line is the only baseline among the three scanning baselines that can completely pass through the entire orbit. However, when displaying the basal ganglia region, the display effect of the image may be lower than that of the image obtained by scanning along the auditory acanthus line or the auditory brow line.

[0087] Among them, compared with the auditory orbit line, the auditory brow line is more parallel or perpendicular to the structures such as the head of the caudate nucleus, the tail of the caudate nucleus, the putamen, the amygdala, and the thalamus, so it is beneficial to the display of the basal ganglia. Therefore, when the to-be-scanned object is a child, the auditory brow line can relatively avoid the lens, which is beneficial to the protection of the eyes.

[0088] Based on the above description, it can be considered that the target scanning baseline is not only related to the age of the object to be scanned, but also related to the target part to be scanned and the area to be imaged in the target part.

[0089] In addition, the above-mentioned tilt represents the tilt angle at which the medical scanning device needs to be tilted during scanning, and the diagonal line represents the target scanning baseline. Based on this, the electronic device can consider that when the medical scanning device is physically tilted by the above-mentioned tilt angle, it can be parallel to the target scanning baseline. That is, it can be considered that the tilt angle at which the medical scanning device needs to be tilted is the first angle between the target scanning baseline (diagonal line) and the scanning direction. Therefore, the electronic device can determine the above-mentioned tilt angle as the first angle. Wherein, the electronic device can determine the first angle based on the adaptive function of the existing positioning frame.

[0090] In another embodiment, based on the above explanation of Figure 3 , after the first angle is determined, the electronic device can also modify it in response to the click operation of the medical staff. Based on this, the electronic device can determine the modified tilt angle as the above-mentioned first angle. Or, since the diagonal line in the positioning frame represents the target scanning baseline, the position information of the target scanning baseline is known. Further, the above-mentioned first angle can be determined based on the position information of the target scanning baseline and the preset scanning direction. In this embodiment, the determination method of the first angle is not limited.

[0091] S202, control the adjustable device to move the target part based on the first angle; the second angle between the target scanning baseline of the moved target part and the scanning direction is smaller than the first angle.

[0092] S203, control the medical scanning device to scan the moved target part.

[0093] In an embodiment, based on the above explanation of the target scanning baseline in S201, it can be considered that when the scanning direction of the medical scanning device is parallel to the target scanning baseline, the quality of the scanning image obtained after the medical scanning device scans the target part is the highest. Therefore, when the adjustable device is controlled to move the target part so that the second angle between the target scanning baseline of the moved target part and the scanning direction is smaller than the first angle, it can be considered that the quality of the scanning image generated when the medical scanning device scans will gradually increase until the second angle is 0°, and the highest quality scanning image can be obtained.

[0094] Based on the above description, in this embodiment, in order to obtain a high-quality scanning image, the electronic device can control the adjustable device to move the target part until the target scanning baseline is parallel to the scanning direction.

[0095] It should be noted that the electronic device can also control the medical scanning device to scan when the target scanning baseline is not parallel to the scanning direction (i.e., the second angle between the target scanning baseline and the scanning direction is not equal to 0°). At this time, the quality of the generated scanning image is lower than that when the scanning direction is parallel to the target scanning baseline, but the electronic device can continue to move without controlling the adjustable device. Therefore, the moving time of the adjustable device can be reduced.

[0096] Based on the above description, it can be considered that the electronic device can not only obtain a scanning image with high quality based on the medical scanning device, but also reduce the moving time of the adjustable device. That is, on the basis of ensuring the quality of the scanning image, the examination time is reduced, thereby improving the examination efficiency, so that the electronic device can achieve balance between the quality of the scanning image and the examination efficiency.

[0097] In another embodiment, different target parts correspond to different adjustable devices. For example, for the head, the corresponding adjustable device can be a movable headrest; for the lumbar spine, the corresponding adjustable device can be a movable half-bridge plate.

[0098] For example, the movable headrest includes but is not limited to a bearing-type movable headrest, an inflatable deformable headrest pad, and the like. It can be understood that when the headrest is bearing-type movable, the inclination height of the headrest relative to the scanning bed can be changed. In turn, the inclination height of the head on the headrest can be adjusted. That is, the body region below the head is lying on the scanning bed, but the head is inclined and lifted by the headrest. In this way, the angle between the target scanning baseline of the head and the scanning direction can be changed.

[0099] Similarly to the bearing-type movable headrest, the inflatable deformable headrest pad can deform according to the amount of inflation. During the deformation process, the inclination height of the deformation can be adjusted, and in turn, the inclination height of the head on the headrest can be adjusted.

[0100] In another embodiment, the headrest pad can also be used in cooperation with the headrest, for example, the headrest pad is arranged in the headrest to make the head of the object to be scanned naturally inclined, so as to reduce the angle between the target scanning baseline and the scanning direction.

[0101] For the half-bridge plate, it can be an arched structure. Wherein, the half-bridge plate can be arched (raised) and sunken relative to the bed plate of the scanning bed after being arranged on the scanning bed, so as to adjust the arching height of the lumbar spine on the half-bridge plate. In turn, the angle between the target scanning baseline and the scanning direction is adjusted.

[0102] In another embodiment, the half-bridge plate can also be composed of an inflatable deformable arched elastic plate, so as to deform based on the amount of inflation, and in turn, adjust the height of the lumbar spine.

[0103] Based on the above description, in this embodiment, the type, structure, movement mode, etc. of the adjustable device are not limited.

[0104] In an embodiment, the electronic device can determine a third angle at which the adjustable device needs to be tilted based on the first angle. Then, the adjustable device is controlled to tilt at the third angle.

[0105] The electronic device can determine the first angle as the third angle, or determine a target tilt angle corresponding to the first angle according to a preset mapping relationship between tilt angles and the first angle, and determine the target tilt angle as the third angle.

[0106] As an example, the mapping relationship can be preset in an actual scenario, and the included angle (first angle) between the target scanning baseline and the scanning direction is determined, and the tilt angle at which the adjustable device needs to be tilted under each included angle is determined. Then, the electronic device can perform data analysis based on multiple sets of included angles and tilt angles to obtain a mapping relationship between the tilt angle and the included angle. The preset analysis includes but is not limited to data correlation analysis, scatter plot, Pearson correlation coefficient, Spearman rank correlation coefficient, regression analysis, etc., which are not limited.

[0107] As an example, refer to Figure 4 , Figure 4 is an application scenario diagram of scanning a target part in a scanning control method of a medical scanning device provided in an embodiment of the present application. The head of the object to be scanned (i.e. the target part) is located in the gantry of the medical scanning device, and the scanning direction of the medical scanning device can be considered as vertical downward. The oblique line of the left head in the upper right corner can be considered as the target scanning baseline, which has a certain angle with the vertical direction. That is, the first angle. At this time, the electronic device can control the headrest (which can be considered as the Figure 4 shadow part below the head) to tilt, and then adjust the target scanning baseline of the head to the vertical direction to be parallel to the scanning direction. That is, the angle is 0°.

[0108] In another embodiment, since different objects to be scanned have different sizes, weights, and shapes, the third angle determined based on the mapping relationship may not be able to make all target scanning baselines parallel to the scanning direction after the target parts are moved.

[0109] Based on this, the electronic device can also pre-train an angle recognition model for determining the third angle, so as to determine the third angle conforming to the to-be-scanned part based on the actual physical condition of the to-be-scanned object. The training data for training the angle recognition model can be data such as the size, weight, shape (or the shape of the target part), the training first angle, and the training third angle, and is not limited herein. In this embodiment, the manner of determining the third angle is not limited.

[0110] It should be noted that, since the adjustable device is located on the scanning bed, the adjustable device can be connected with the control system of the scanning bed and adjusted by the instruction of the scanning bed. At this time, when adding a control module of the adjustable device to the control system, the material of the control module should be selected to be a material that does not cause artifacts when the medical scanning device is scanning.

[0111] For example, when the medical scanning device is a CT device, the CT device is easily affected by metal materials during scanning. Therefore, the material of the control module can be a non-metal material, or the shell of the control module is formed of a non-metal material. For example, rubber or plastic materials.

[0112] In this embodiment, when the target part of the to-be-scanned object is scanned, the first angle between the target scanning baseline in the target part and the scanning direction of the medical scanning device can be determined according to the positioning image capable of describing the position of the target part of the to-be-scanned object. Since the target scanning baseline is used to describe the expected scanning direction when the target part is scanned by the medical scanning device, the adjustable device can be controlled to move the target part based on the first angle, so that the second angle between the target scanning baseline of the moved target part and the scanning direction is less than the first angle. That is, the scanning direction of the medical scanning device is closer to the expected scanning direction, so as to improve the image quality generated when the medical scanning device scans the moved target part. Based on this, the target part is moved by the adjustable device which can be conveniently controlled, so as to adjust the angle between the target scanning baseline and the scanning direction. In this way, when the positioning of the to-be-scanned object is not ideal, the positioning of the to-be-scanned object does not need to be actively adjusted, and the medical scanning device does not need to be physically tilted. Further, on the basis of ensuring the image quality of the final scanning image, the examination time is reduced and the examination efficiency is improved. Moreover, only the adjustable device needs to be adjusted, so that the collision risk caused by the physical tilting of the medical scanning device can be avoided.

[0113] Based on the above S201-S203 steps, it is only an example of adjusting the target scanning baseline by controlling the adjustable device. In another embodiment, the electronic device can also control the medical scanning device to be physically tilted at the same time, so as to further reduce the examination time.

[0114] For example, after obtaining the first angle, the electronic device can determine a fourth angle at which the medical scanning device needs to be tilted and a fifth angle at which the adjustable device needs to be tilted based on the first preset angular velocity at which the medical scanning device tilts and the second angular velocity at which the adjustable device tilts. The sum of the fourth angle and the fifth angle is equal to the first angle. Then, the medical scanning device is controlled to tilt by the fourth angle, and the adjustable device is controlled to tilt by the fifth angle.

[0115] Specifically, the electronic device can obtain a target angular velocity by adding the first angular velocity and the second angular velocity. Then, the first angle is divided by the target angular velocity to obtain a motion duration. At this time, the product of the first angular velocity and the motion duration is the fourth angle at which the medical scanning device needs to be tilted, and the product of the second angular velocity and the motion duration is the fifth angle at which the adjustable device needs to be tilted.

[0116] It can be understood that, after the fourth angle and the fifth angle are calculated based on the above manner, it can be considered that the time required for the medical scanning device to tilt by the fourth angle at the first preset angular velocity is the same as the time required for the adjustable device to tilt by the fifth angle at the second preset angular velocity. Further, the parallel between the target scanning baseline and the scanning direction in the entire examination process can be completed only by the above motion duration (the first angle divided by the target angular velocity). Compared with the time required for the adjustable device to move to complete the parallel between the target scanning baseline and the scanning direction (the first angle divided by the second preset angular velocity), the time required for simultaneously controlling the medical scanning device and the adjustable device is less, so as to further improve the examination efficiency.

[0117] Moreover, since the medical scanning device only needs to tilt by the fourth angle at this time, it does not need to be tilted greatly, and thus the collision risk caused by physical tilting of the medical scanning device can be reduced.

[0118] In another embodiment, with reference to Figure 5 , Figure 5 An embodiment of the present application provides a medical system, comprising a medical scanning device 10, a scanning bed 20, and an adjustable device 30. Specifically, the adjustable device 30 is arranged on the scanning bed 20, and the medical scanning device 10 is connected with the adjustable device 30.

[0119] The medical scanning device 10 is configured to scan a target part of a to-be-scanned object located on the scanning bed 20, and send a first angle to the adjustable device 30. The first angle is used to describe an angle between a target scanning baseline in the target part and a scanning direction of the medical scanning device 10. The target scanning baseline is used to describe an expected scanning direction when the target part is scanned by the medical scanning device 10.

[0120] The adjustable device 30 is configured to receive the first angle and control the target part to move.

[0121] In an embodiment, the above steps S201-S203 have been explained with the medical scanning device 10, the adjustable device 30, the first angle, the target scanning baseline and the scanning direction, and no further description is given. It should be noted that the above connection includes but is not limited to a communication connection, a cable connection and the like, and is not limited.

[0122] In an embodiment, the above steps S201-S203 have been explained with the medical scanning device 10, the adjustable device 30, the first angle, the target scanning baseline and the scanning direction, and no further description is given. It should be noted that the above connection includes but is not limited to a communication connection, a cable connection and the like, and is not limited.

[0123] As an example, refer to Figure 6 , Figure 6 is an implementation flowchart of a scanning control method of a medical scanning device according to another embodiment of the present application. Taking the target part as the head, the adjustable device as the headrest, and the medical scanning device 10 as the CT device as an example. After the to-be-scanned object enters the scanning room, the medical staff can guide the to-be-scanned object to position. For example, guide the to-be-scanned object to lie on the scanning bed 20, the head is placed in the headrest, and guide the chin of the to-be-scanned object to be low. After the to-be-scanned object lies down, the medical staff can place the headrest pad inside the headrest to make the head of the to-be-scanned object naturally inclined, and reduce the first angle between the scanning direction of the CT device and the target scanning baseline.

[0124] Then, the CT device can perform a scout view scan on the head of the to-be-scanned object to obtain a scout view of the target part. Then, based on the scout frame adaptive function, a scout frame is generated in the scout view in response to the information configuration instruction of the medical staff to determine the target part to be scanned and the first angle. Then, the CT device can send the first angle to the control module of the headrest.

[0125] Finally, the control module can determine the third angle at which the headrest needs to be inclined based on the first angle, and generate a corresponding control instruction to control the headrest to be inclined. After the inclination is completed, the CT device can perform scanning on the target part to obtain a scan image.

[0126] In this embodiment, when the target scanning baseline of the target part needs to be parallel to the scanning direction of the medical scanning device, the medical system can control the adjustable device to move the target part to adjust the first angle between the target scanning baseline and the medical scanning device, without the need for the medical scanning device to be physically inclined greatly. Further, the examination time can be reduced and the examination efficiency can be improved on the basis of ensuring the image quality of the final scan image.
