Description

Technical Field

[0001] The present application belongs to the field of image scanning technology, and in particular, relates to a scanning control method, system, device and electronic equipment for medical scanning equipment. Background Art

[0002] In medical scanning, the object to be scanned is usually scanned by a medical scanning device. For example, the medical scanning device may be a computed tomography (CT) device. In addition, in the actual scanning process, the medical scanning device is usually required to scan along the desired scanning direction of the object to be scanned in order to obtain a high-quality scanned image.

[0003] Currently, in order to obtain high-quality scanned images, medical scanning equipment is usually required to be tilted at a certain angle along the desired scanning direction, or medical staff are required to actively adjust the position of the object to be scanned to an ideal position.

[0004] However, the structure of medical scanning equipment is complex and relatively large, and it usually takes a long time to physically tilt the device, and it also takes a long time to return to the initial position. Therefore, the examination time will be increased, affecting the efficiency of the department's examination. In addition, when medical staff actively adjust the position of the object to be scanned, they need to scan and preview the scanned image after each adjustment until the position of the object to be scanned is the ideal position and a high-quality scanned image is obtained. At this time, multiple positioning will also increase the examination time, thereby affecting the efficiency of the examination. Summary of the invention

[0046] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0047] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations 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 this application is performed with the user's knowledge and permission, that is, the information collection process / feature extraction process complies with the requirements of laws and regulations and does not constitute an act that harms the public interest.

[0049] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions 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 may be CT, positron emission tomography CT (PET-CT), etc., without limitation. In addition, in the actual scanning process, the medical scanning device is usually required to scan along the desired scanning direction of the object to be scanned in order to obtain a high-quality scanned image.

[0051] Currently, in order to obtain high-quality scanned images, medical scanning equipment is usually required to be tilted at a certain angle along the desired scanning direction before scanning, or medical staff are required to actively adjust the position of the object to be scanned to an ideal position.

[0052] However, medical scanning equipment is complex and bulky, and usually takes a long time to physically tilt and return to its original position, which increases the examination time and affects the efficiency of the department's examination.

[0053] For example, refer to Figure 1 , Figure 1 It is a schematic diagram of an application scenario for scanning an object to be scanned in the prior art. Taking the medical scanning device as a CT device, it is necessary to scan the head of the object to be scanned as an example for explanation. In a head CT scan, in order to obtain a clear basal ganglia level image, a suitable target scanning baseline (that is, the expected scanning direction when the head is scanned) is usually selected according to the specific situation of the object to be scanned. Among them, in CT head scans, common target scanning baselines include but are not limited to the auditory canthal line, auditory eyebrow line and auditory orbital line. This example is explained using the auditory canthal line as an example.

[0054] Reference Figure 1 , the subject to be scanned needs to lie on the scanning bed, with the head in the gantry of the medical scanning device. When the gantry scans the head flat, the head needs to be scanned along the auditory canthus line. At this time, the gantry usually needs to be tilted 15°. For example, along Figure 1 The arrow corresponding to the tilt in the figure on the right is tilted. Tilt represents the tilt angle of the rack during scanning. “-” and “+” represent the direction of the rack tilt.

[0055] However, it usually takes 20 seconds to physically tilt the rack by 15°, and the tilted rack needs to be restored after the inspection. In other words, it can be considered that it takes at least 40 seconds to perform a scanning inspection when the rack is physically tilted, which greatly affects the inspection efficiency.

[0056] In addition, there may be a risk of collision when the rack is physically tilted. For example, when the subject to be scanned brings his own drip stand, hospital bed and other devices into the scanning room for examination, there may be a risk of collision between the medical scanning equipment and the drip stand, hospital bed and other devices.

[0057] Also, when medical staff actively adjust the position of the object to be scanned, they need to scan and preview the scanned image after each adjustment until the position of the object to be scanned is the ideal position and a high-quality scanned image is obtained. At this time, multiple positioning will also increase the examination time, thereby affecting the examination efficiency.

[0058] Based on this, in order to reduce the inspection time and improve the inspection efficiency on the basis of obtaining high-quality scanned images, the embodiment of the present application provides a scanning control method for a medical scanning device, which can be applied to a medical system. Exemplarily, it can be applied to electronic devices such as medical scanning devices and controllers in a medical system, and the embodiment of the present application does not impose any restrictions on the specific type of electronic equipment.

[0059] See also Figure 2 , Figure 2 A flowchart of a scanning control method for a medical scanning device provided in an embodiment of the present application is shown, and the method includes the following steps:

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

[0061] In one embodiment, the object to be scanned may be a person or an animal, and this is not limited. However, it should be noted that when the object to be scanned is an animal, since the animal will not quietly cooperate with the medical staff for scanning, the animal needs to be in a sleeping state. In this embodiment, the object to be scanned is mainly explained as a person.

[0062] In one embodiment, the positioning image can be considered as image data generated after the medical scanning device performs positioning scanning on the target part, which can be used to describe the position of the target part. That is, it describes the spatial position of the target part in the coordinate system corresponding to the medical scanning device. Among them, since the positioning image can describe the position of the target part, the positioning image can also provide a positioning reference for the subsequent scanning and reconstruction of the medical scanning device.

[0063] In one embodiment, the target scanning baseline is used to describe the desired scanning direction when the target part is scanned by the medical scanning device. The target scanning baseline can be set in advance 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. Different objects to be scanned or different target parts to be scanned usually have different corresponding target scanning baselines.

[0064] In one embodiment, when the medical scanning device is not tilted or moved, the scanning direction of the medical scanning device is usually fixed. Based on this, it can be considered that the scanning direction of the medical scanning device is a fixed direction and can be pre-stored in the electronic device.

[0065] As an example, the scanning direction may be the direction in which the medical scanning device emits the scanning factor. When the types of the medical scanning device are different, the scanning factors are also different. For example, when the medical scanning device is a CT device, the scanning factor may be a ray; when the medical scanning device is an ultrasonic device, the scanning factor may be an ultrasonic wave, and there is no limitation on this.

[0066] For example, if the scanning device is an electron beam CT device, a plurality of target rings and an electron gun corresponding to each target ring are arranged on the rack. The electron gun is used to emit X-rays and reach the target ring corresponding to the electron gun. At this time, the direction in which the electron gun emits and reaches 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. Figure 1 , it can be considered that in the preset coordinate system, the vertical direction of the frame is the XY plane, and the horizontal direction of the object to be scanned lying flat on the scanning bed is the Z direction (that is, the moving direction of the scanning bed). At this time, the scanning direction of the medical device can be considered to be a direction that coincides with or is parallel to the XY plane.

[0068] Among them, since the positioning 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. In addition, since the positioning 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 above-mentioned first angle according to the position information of the target scanning baseline and the position information corresponding to the scanning direction. Among them, the first angle can be calculated according to the angle calculation formula between two line segments, which is not described in detail.

[0069] In another embodiment, the electronic device may also generate a positioning frame in the positioning image, and determine the baseline direction of the target scanning baseline in the positioning frame, and then determine the angle between the baseline direction and the scanning direction as the first angle.

[0070] The positioning frame can be used to determine the range that the medical scanning device needs to scan for subsequent scanning and reconstruction. For example, when scanning the object to be scanned, the medical scanning device may not need to scan the entire body of the object to be scanned, but may only scan the target part of the object to be scanned.

[0071] It can be understood that by limiting the target part to be scanned based on the positioning frame, the range that needs to be scanned by the medical scanning device can be reduced, thereby reducing the working time of the medical scanning device.

[0072] In one embodiment, the target part includes but is not limited to the head, lumbar spine and other parts, and the specific type of the target part is not limited in this embodiment. There can be one or more target parts.

[0073] In one embodiment, different target scanning baselines usually pass through different specific human tissues at the target site. Therefore, the electronic device can identify the tissue positions where at least two human tissues are located corresponding to the target scanning baseline. Then, the direction of the line connecting the two tissue positions is used to determine the baseline direction.

[0074] The human tissues that each target scanning baseline needs to pass through can be set in advance. Exemplarily, when the target scanning baseline is the ear-brow line, the human tissues it passes through can include eyebrows and skull base. And, when the target scanning baseline is the ear-orbit line, the human tissues it passes through can include eye sockets and skull base. In this embodiment, the human tissues corresponding to each target scanning baseline are not limited.

[0075] Furthermore, the electronic device may pre-set a human tissue recognition model to perform image model processing on the positioning image to determine the image position corresponding to the human tissue. The human tissue recognition model may be constructed and trained based on a neural network model capable of processing images, which will not be described in detail.

[0076] In one embodiment, a pre-trained positioning frame generation model may be provided in the electronic device, which can recognize the positioning image and output the positioning frame. In another embodiment, the electronic device may also generate a positioning frame in the positioning image in response to the information configuration instruction. In this embodiment, the method for generating the positioning frame is not limited.

[0077] Exemplarily, after generating the positioning image, the electronic device may display an information configuration input box for the positioning frame. At this time, the electronic device may generate an information configuration instruction and respond based on the information input by the medical staff in the information input configuration box to generate a positioning frame in the positioning image.

[0078] The information that can be input in the information input configuration box includes, but is not limited to: the starting position of the positioning frame (for example, it can be the upper left corner position), the ending position (for example, it can be the lower right corner position), the length of the positioning frame, the scanning direction (the scanning direction of the medical scanning device), the collimation width, the tilt angle (the angle at which the medical scanning device should be tilted when scanning), FOV (Field Of View), Center X or Center Y (coordinate parameters of the horizontal and vertical coordinates of the positioning frame, which can be represented by the center point or each corner point of the positioning frame), and one or more other information, and no limitation is made to this.

[0079] As an example, see Figure 3 , Figure 3This is a schematic diagram of an application scenario of a positioning box in a scanning control method of a medical scanning device provided by an embodiment of the present application. Among them, the "2" in 2Head Axlal corresponding to the serial number 1 in the circle represents the scanning protocol in the medical scanning device. The "2.1" and "2.2" corresponding to the serial number 2 in the circle represent the serial numbers of the positioning box sequence, and the positioning box can be selected by clicking the serial number. Among them, after selecting the scanning protocol, the electronic device can respond to the information configuration instruction to automatically configure the scanning protocol with multiple sequence parameters required for scanning, and obtain the final target scanning protocol. At this time, the medical scanning device can scan the target part based on the parameter information configured in the target scanning protocol. Among them, the sequence parameters to be configured corresponding to the scanning protocol can refer to the various information corresponding to the above-mentioned information input configuration box, and no further explanation is given.

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

[0081] It should be added that Figure 3The slash in the figure can be considered as the target scanning baseline when the medical scanning device is expected to scan, which can be bound to the above scanning protocol, or determined in response to the information configuration instruction of the medical staff, and there is no limitation on this. 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] It has been explained above that different objects to be scanned or different target parts to be scanned have corresponding target scanning baselines that are usually different. For example, for the same target part, when the ages of the objects to be scanned are different, the corresponding target scanning baselines may be different; and for the same object to be scanned, when the target parts to be scanned of the object to be scanned are different, the corresponding target scanning baselines are also usually different.

[0083] As an example, when the target part is the head, in order to obtain a clear basal ganglia level image, a suitable target scanning baseline is usually selected according to the specific situation of the object to be scanned. For example, in a head scan, the common scanning baselines described above include the auditory canthus line, the auditory eyebrow line, and the auditory orbital line. Among them, when a CT scan is performed with the auditory canthus line as the target scanning baseline, a scanning image at the basal ganglia level can be obtained more accurately.

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

[0085] In addition, when the brow line is used as the target scanning baseline, it can take into account the lowest point of the three cranial fossae, and it also has a good effect in displaying the fourth ventricle and basal ganglia.

[0086] Also, the auditory orbital line is mainly used to scan orbital lesions, but in some cases, by adjusting the scanning direction, images of the basal ganglia can also be obtained. Therefore, the auditory orbital line is the only baseline among the three scanning baselines that can completely pass through the entire orbit. However, when displaying the basal ganglia, the display effect of its image may be lower than that of the image obtained by scanning along the auditory canthal line or auditory eyebrow line.

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

[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 to the target part to be scanned and the area in the target part to be imaged and displayed.

[0089] In addition, it has been explained above that tilt represents the tilt angle that the medical scanning device needs to tilt during scanning, and the oblique line represents the target scanning baseline. Based on this, the electronic device can assume that when the medical scanning device is physically tilted at the above tilt angle, it can be parallel to the target scanning baseline. In other words, it can be assumed that the tilt angle that the medical scanning device needs to tilt is the first angle between the target scanning baseline (oblique line) and the scanning direction. Therefore, the electronic device can determine the above tilt angle as the first angle. Among them, 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 Figure 3 It can be seen from the explanation that after determining the first angle, 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. Alternatively, since the oblique line in the positioning box represents the target scanning baseline, the position information of the target scanning baseline is known. Furthermore, 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 method for determining the first angle is not limited.

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

[0092] S203: Control the medical scanning device to scan the moved target part.

[0093] In one embodiment, based on the explanation of the target scanning baseline in S201 above, 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 scanned 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 and the scanning direction of the moved target part is smaller than the first angle, it can be considered that the quality of the scanned image generated by the medical scanning device during scanning will gradually increase until the highest quality scanned image can be obtained when the second angle is 0°.

[0094] Based on the above description, in this embodiment, in order to obtain a high-quality scanned 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 (that is, the second angle between the target scanning baseline and the scanning direction is not equal to 0°). At this time, although the quality of the generated scanned image is lower than the quality of the scanned image when the scanning direction is parallel to the target scanning baseline, the electronic device does not need to control the adjustable device to continue to move. Therefore, the movement time of the adjustable device can be reduced.

[0096] Based on the above description, it can be considered that the electronic device can reduce the moving time of the adjustable device on the basis of being able to obtain a high-quality scanned image based on the medical scanning device. That is, on the basis of ensuring the quality of the scanned image, the inspection time is reduced, thereby improving the inspection efficiency, so that the electronic device can achieve a balance between the quality of the scanned image and the inspection efficiency.

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

[0098] Exemplarily, the movable headrest includes but is not limited to a headrest that moves in a bearing-like manner and an inflatable and deformable headrest pad, which is not limited thereto. It is understandable that when the headrest moves in a bearing-like manner, the tilt height of the headrest relative to the scanning bed can be changed. Furthermore, the tilt height of the head located on the headrest can be adjusted. That is, the body area below the head lies flat on the scanning bed, but the head is tilted 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] Similar to the headrest with bearing-type motion, the inflatable deformable headrest cushion can be deformed according to the amount of inflation. During the deformation process, the tilt height of the deformation can be adjusted, thereby adjusting the tilt height of the head on the headrest.

[0100] In another embodiment, the head support pad can also be used in conjunction with the head support. For example, the head support pad is arranged in the head support to naturally tilt the head of the object to be scanned to reduce the angle between the target scanning baseline and the scanning direction.

[0101] The half-bridge plate may be an arched structure. After being arranged on the scanning bed, the half-bridge plate may arch (rise) and sink relative to the bed plate of the scanning bed to adjust the arch height of the lumbar vertebrae on the half-bridge plate. In addition, the angle between the target scanning baseline and the scanning direction is adjusted.

[0102] In another embodiment, the half-bridge plate may also be composed of an inflatable and deformable arched elastic plate, so as to deform based on the inflation amount, thereby adjusting the lumbar vertebrae height.

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

[0104] In one embodiment, the electronic device may determine a third angle at which the adjustable device needs to be tilted based on the first angle, and then control the adjustable device to tilt at the third angle.

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

[0106] As an example, the above mapping relationship can be pre-set in an actual scenario, with multiple angles (first angles) between the target scanning baseline and the scanning direction, and the inclination angle at which the adjustable device needs to be tilted at each angle is determined. Afterwards, the electronic device can perform data analysis based on multiple sets of angles and inclination angles to obtain a mapping relationship that can describe the inclination angle and the angle. Among them, the preset analysis includes but is not limited to data association analysis, scatter plot, Pearson correlation coefficient, Spearman rank correlation coefficient, regression analysis, etc., which are not limited to this.

[0107] As an example, see Figure 4 , Figure 4 This is a schematic diagram of an application scenario of scanning a target part in a scanning control method of a medical scanning device provided by an embodiment of the present application. The head of the object to be scanned (i.e., the target part) is located in the frame of the medical scanning device, and the scanning direction of the medical scanning device can be considered to be vertically downward. The oblique line on the left side of the head at 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 head support (which can be considered as Figure 4 The target scanning baseline of the head is adjusted to a vertical direction so as to be parallel to the scanning direction, that is, the angle is 0°.

[0108] In another embodiment, since different objects to be scanned usually have different sizes, weights, and shapes, after the adjustable device moves the target part based on the third angle determined by the mapping relationship, it may not be possible to make the target scanning baseline corresponding to all the target parts move parallel to the scanning direction.

[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 that matches the part to be scanned based on the actual physical condition of the object to be scanned. The training data used to train the angle recognition model can be data such as body size, weight, shape (or shape of the target part), training first angle, and training third angle, etc., without limitation. In this embodiment, the method for determining the third angle is not limited.

[0110] It should be added that, since the adjustable device is located on the scanning bed, the adjustable device can be connected to the control system of the scanning bed and adjusted according to the instructions of the scanning bed. At this time, when a control module of the adjustable device is added to the control system, the material of the control module should be selected from materials that do not cause artifacts when the medical scanning device is scanning.

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

[0112] In this embodiment, when scanning the target part of the object to be 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 that can describe the position of the target part of the object to be scanned. Among them, 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 and the scanning direction of the target part after the movement is smaller than the first angle. That is, the scanning direction of the medical scanning device is made closer to the expected scanning direction 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 that can be easily controlled to adjust the angle between the target scanning baseline and the scanning direction, when the position of the object to be scanned is not ideal, there is no need to actively adjust the position of the object to be scanned, and there is no need for the medical scanning device to be physically tilted. Furthermore, on the basis of ensuring the image quality of the final scanned image, the inspection time can be reduced and the inspection efficiency can be improved. In addition, only the adjustable device needs to be adjusted, so the collision risk caused by the physical tilt of the medical scanning device can be avoided.

[0113] In summary, the above description of steps S201-S203 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 synchronously perform physical tilting to further reduce the inspection time.

[0114] For example, after acquiring the first angle, the electronic device can determine the fourth angle at which the medical scanning device needs to be tilted, and the fifth angle at which the adjustable device needs to be tilted, respectively, based on the first preset angular velocity when the medical scanning device is tilted and the second angular velocity at which the adjustable device is tilted. 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 at the fourth angle, and the adjustable device is controlled to tilt at the fifth angle at the same time.

[0115] Specifically, the electronic device can add the first angular velocity and the second angular velocity to obtain the target angular velocity. Then, the first angle is divided by the target angular velocity to obtain the 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 is understandable that after calculating the fourth angle and the fifth angle based on the above method, it can be considered that the time required for the medical scanning device to tilt the fourth angle at the first preset angular velocity is the same as the time required for the adjustable device to tilt the fifth angle at the second preset angular velocity. Furthermore, it can be achieved that during the entire inspection process, only the above movement time (first angle divided by target angular velocity) is required to complete the parallelism of the target scanning baseline with the scanning direction. Compared with the time required for controlling the adjustable device alone to move to complete the parallelism of the target scanning baseline with the scanning direction (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 inspection efficiency.

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

[0118] In another embodiment, referring to Figure 5 , Figure 5 An embodiment of the present application provides a medical system, including: a medical scanning device 10, a scanning bed 20 and an adjustable device 30. Specifically, the adjustable device 30 is disposed on the scanning bed 20; the medical scanning device 10 is connected to the adjustable device 30.

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

[0120] The adjustable device 30 is used to receive the first angle and control the movement of the target part.

[0121] In one embodiment, the above steps S201-S203 have explained the medical scanning device 10, the adjustable device 30, the first angle, the target scanning baseline and the scanning direction, which will not be described again. It should be noted that the above connection includes but is not limited to communication connection, cable connection and other methods, which are not limited to this.

[0122] The above-mentioned scanning of the target part of the object to be scanned includes a positioning scan for generating a positioning image and a subsequent scanning for scanning and reconstructing the target part of the object to be scanned, which will not be described in detail.

[0123] As an example, see Figure 6 , Figure 6 This is a flow chart for implementing a scanning control method of a medical scanning device provided by another embodiment of the present application. Take the target part as the head, the adjustable device as the headrest, and the medical scanning device 10 as a CT device as an example. After the object to be scanned enters the scanning room, the medical staff can guide the object to be scanned to position. For example, guide the object to be scanned to lie flat on the scanning bed 20, place the head in the headrest, and guide the chin of the object to be scanned to lower. After the object to be scanned lies down, the medical staff can place a headrest pad inside the headrest to make the head of the object to be scanned tilt naturally, thereby reducing the first angle between the scanning direction of the CT device and the target scanning baseline.

[0124] Afterwards, the CT device can perform a positioning image scan on the head of the subject to be scanned to obtain a positioning image of the target part. Then, based on the positioning frame adaptive function, in response to the information configuration instruction of the medical staff, a positioning frame is generated in the positioning image 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 head support.

[0125] Finally, the control module can determine the third angle at which the head support needs to be tilted based on the first angle, and generate a corresponding control instruction to control the tilting of the head support. After the tilting is completed, the CT device can scan the target part to obtain a scanned 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 and adjust the first angle between the target scanning baseline and the medical scanning device, without requiring the medical scanning device to perform a large physical tilt. In addition, the inspection time can be reduced and the inspection efficiency can be improved while ensuring the image quality of the final scanned image.
