Description

Technical Field

[0002] In current medical imaging technologies, such as CT (computed tomography) and MR (magnetic resonance imaging), patient positioning is a crucial step. In order to ensure the accuracy of the image and the effectiveness of the diagnosis, the patient's positioning (raising hands, shrugging shoulders, etc.) usually requires guidance and assistance from the operating technician or nurse. This process usually involves close communication between the technician or nurse and the patient to ensure that the patient can be positioned in the required posture.

[0003] However, this traditional positioning method has the following major problems:

[0004] 1) High communication cost: Technicians or nurses need to spend a lot of time communicating with patients and guiding them to the correct position, which not only increases the time cost of the medical process, but also may affect the comfort of patients;

[0005] 2) High labor cost: Since positioning requires the participation of professionals, this increases the investment in human resources, which may lead to a shortage of human resources, especially in a high workload environment;

[0006] 3) Low examination efficiency: Traditional positioning methods may lead to inaccurate positioning, which affects the efficiency of the examination and the quality of the image. The patient's posture needs to be readjusted, which further increases the examination time;

[0067] Based on the problems existing in the prior art, the present disclosure provides a method for adjusting the patient position in a CT scanning system. Figure 1 FIG. 1 is a flow chart of a method for adjusting the patient position in a CT scanning system provided by an embodiment of the present disclosure, such as Figure 1 As shown, the patient positioning adjustment method in the CT scanning system includes:

[0068] S110 . Determine joint position information of each joint of the target object according to the acquired three-dimensional image data of the target object.

[0069] In the patient positioning adjustment method in the CT scanning system provided by the embodiment of the present disclosure, an image acquisition terminal is arranged above or on both sides of the CT scanning bed, and three-dimensional image data of the target object is acquired by the image acquisition terminal. After acquiring the three-dimensional image data of the target object, the image acquisition terminal sends the sampled three-dimensional image data of the target object to a terminal device. The terminal device obtains the joint position information of each joint of the target object by processing, analyzing and identifying the three-dimensional image data of the target object.

[0070] Among them, the image acquisition terminal can be but is not limited to video acquisition devices such as depth cameras. The image acquisition terminal can acquire three-dimensional image data (length, width, and height) of the patient (target object), and based on the acquired three-dimensional image data of the patient, identify the patient's specific posture and joint position information of each joint.

[0071] The terminal is set to process, analyze and identify the three-dimensional image data of the target object to obtain the joint position information of each joint of the target object. The terminal can identify the specific posture of the target object based on the posture recognition algorithm, and then determine the joint position information of each joint of the target object according to the identified specific posture of the target object. The posture recognition algorithm can be but is not limited to posture recognition technology using a deep learning algorithm model, and the model can be trained using motion sample data.

[0072] S120. Determine the target joint and associated joints according to the scanning parameters.

[0073] The scanning parameters at least include the scanning range.

[0074] Specifically, in a CT scanning system, the CT scanning system needs to set scanning parameters, including scanning range, slice thickness, slice spacing, scanning time, etc. For example, the scanning range of a head CT scan is usually from the base of the skull to the entrance of the chest cavity, and the slice thickness and slice spacing can be adjusted according to specific needs. The scanning parameters are set by technicians or nurses based on the diagnosis form issued by the attending physician.

[0075] After receiving the scanning parameters, the terminal device can determine information such as the scanning range of the target object, and determine the target joints and associated joints within the scanning range based on the correspondence between the scanning range and each joint.

[0076] As an exemplary example, after receiving the scanning parameters, the terminal device determines that the scanning range is from the head to the chest. Then, based on the correspondence between the scanning range and each joint, the target joint is determined to be the elbow joint, and the associated joints are determined to be the hand joints and shoulder joints connected to the elbow joint, and the neck joints and head joints that are not connected to the elbow joint.

[0077] As a preferred implementation, there is a correspondence between the scanning parameters and the joint numbers, that is, after the scanning parameters are determined, it can be determined which joint numbers the target joints include, which joint numbers the associated joints include, and the correspondence between the target joints and the associated joints, etc., which can all be pre-set.

[0078] It should be noted that, in the patient positioning adjustment method in the CT scanning system provided by the embodiment of the present disclosure, the correspondence between the scanning parameters and the target joints and the associated joints is preset in advance, that is, if the scanning range is between the head range and the chest range, the target joint is the elbow joint, and the associated joints are the hand joints and shoulder joints connected to the elbow joint, and the neck joints and head joints that are not connected to the elbow joint.

[0079] In addition, it should be noted that within a scanning range, there may be one or more target joints, and associated joints associated with different target joints may overlap, which is not specifically limited in the embodiments of the present disclosure.

[0080] S130. Determine the positioning state information of the target object according to the relationship between the target joint position information of the target joint, the joint position information of the associated joint and the preset joint position information.

[0081] After the target joint and the associated joints are determined in step S120, the actual angle information of the target joint can be determined based on the target joint position information of the target joint and the joint position information of the two associated joints connected to the target joint, as well as the actual distance information of the target joint and any associated joint not connected to the target joint. Therefore, based on the actual angle information of the target joint and the actual distance information of the target joint and any associated joint not connected to the target joint, the positioning state information of the target joint of the target object can be determined.

[0082] As a specific implementation, according to the relationship between the target joint position information of the target joint, the joint position information of the associated joints and the preset joint position information, the positioning state information of the target object is determined, including: obtaining the first joint position information of the first associated joint connected to the target joint and the second joint position information of the second associated joint, and the third joint position information of the third associated joint not connected to the target joint; determining the actual angle information of the target joint according to the target joint position information of the target joint, the first joint position information of the first associated joint and the second joint position information of the second associated joint; determining the actual distance information between the target joint and the third associated joint according to the target joint position information of the target joint and the third joint position information of the third associated joint; determining the positioning state information of the target object according to the actual angle information and the actual distance information of the target joint.

[0083] Among them, determining the positioning state information of the target object according to the actual angle information and the actual distance information of the target joint includes: obtaining the preset angle information of the target joint and the preset distance information of the target joint; determining the angle matching value of the target joint according to the relationship between the actual angle information of the target joint and the preset angle information; determining the distance matching value of the target joint according to the relationship between the actual distance information of the target joint and the preset distance information; determining the positioning state information of the target object according to the angle matching value and the distance matching value of the target joint.

[0084] Determine the positioning status information of the target object according to the angle matching value and the distance matching value of the target joint, including: obtaining a first weighted value corresponding to the angle matching value of the target joint and a second weighted value corresponding to the distance matching value; determine the similarity between the positioning of the target object and a preset positioning according to the angle matching value, the first weighted value, the distance matching value and the second weighted value of the target joint; when the similarity between the positioning of the target object and the preset positioning is greater than or equal to the preset similarity, determine the positioning status information of the target object to be a positioning success status; when the similarity between the positioning of the target object and the preset positioning is less than the preset similarity, determine the positioning status information of the target object to be a positioning failure status.

[0085] To illustrate with a specific embodiment, if the scanning range is between the head range and the chest range, the target joint is the elbow joint, the associated joints are the hand joint and the shoulder joint connected to the elbow joint, and the neck joint and the head joint that are not connected to the elbow joint, that is, the first associated joint is the hand joint, the second associated joint is the shoulder joint, and the third associated joints are the neck joint and the head joint, respectively. At this time, firstly, according to the joint position information of the elbow joint, the joint position information of the hand joint and the joint position information of the shoulder joint, the actual angle information of the elbow joint is determined, and then according to the joint position information of the elbow joint and the joint position information of the neck joint, the actual distance information of the elbow joint from the neck joint is determined, and according to the joint position information of the elbow joint and the joint position information of the head joint, the actual distance information of the elbow joint from the head joint is determined, and finally, according to the actual angle information of the elbow joint, the actual distance information of the elbow joint from the neck joint and the actual distance information of the elbow joint from the head joint, the positioning state information of the target object is determined.

[0086] In a specific implementation, in a specific process of determining the positioning state information of the target object according to the actual angle information of the elbow joint, the actual distance information of the elbow joint from the neck joint, and the actual distance information of the elbow joint from the head joint: first, the angle matching value of the elbow joint is determined according to the actual angle information of the elbow joint and the preset angle information of the elbow joint; then, the first distance matching value of the elbow joint is determined according to the relationship between the actual distance information of the elbow joint from the neck joint and the preset distance information; and the second distance matching value of the elbow joint is determined according to the relationship between the actual distance information of the elbow joint from the head joint and the preset distance information; finally, the similarity between the positioning of the target object and the preset positioning is determined according to the angle matching value, the first distance matching value, the second distance matching value, and the corresponding weighted values; when the similarity between the positioning of the target object and the preset positioning is greater than or equal to the preset similarity, the positioning state information of the target object is determined to be a positioning success state; when the similarity between the positioning of the target object and the preset positioning is less than the preset similarity, the positioning state information of the target object is determined to be a positioning failure state.

[0087] Specifically, the angle matching value of the target joint is calculated in the following way:

[0088] ,

[0089] in, is the angle matching value of the joint numbered x, is the preset angle information of the joint numbered x. The actual angle information of the joint numbered x.

[0090] The distance matching value of the target joint satisfies:

[0091] ,

[0092] Among them, y is the number of the third associated joint, is the distance matching value between the joint numbered x and the joint numbered y, The preset distance information between the joint numbered x and the joint numbered y. The actual distance information between the joint numbered x and the joint numbered y.

[0093] When x is the number of the elbow joint, if the preset angle information of the elbow joint is , according to the joint position information of the elbow joint, the joint position information of the hand joint and the joint position information of the shoulder joint, the actual angle information of the elbow joint is determined as , then the angle matching value of the elbow joint satisfies .

[0094] When x is the number of the elbow joint, y1 is the number of the neck joint, and y2 is the number of the head joint, the preset distance information between the elbow joint and the neck joint is , , according to the joint position information of the elbow joint and the joint position information of the neck joint, the actual position information of the elbow joint is determined as , according to the joint position information of the elbow joint and the joint position information of the head joint, the actual position information of the elbow joint is determined as , then the distance matching value between the elbow joint and the neck joint is full , then the distance matching value between the elbow joint and the head joint satisfies .

[0095] By matching the angle of the elbow joint to the value that satisfies , the distance matching value between the elbow joint and the neck joint satisfies The distance matching value between the elbow joint and the head joint satisfies The weighted average is performed to obtain the similarity between the target object's position and the preset position.

[0096] It should be noted that in the above embodiment, the target joint is exemplarily represented as one joint. In other implementable modes, when the target joint is multiple joints, the angle matching values ​​and distance matching values ​​of the multiple target joints are obtained respectively, and then the similarity between the position of the target object and the preset position is determined according to the angle matching values ​​and distance matching values ​​corresponding to the different target joints. The more the number of target joints to be compared, the higher the similarity between the position of the determined target object and the preset position.

[0097] Furthermore, the posture features that need to be compared may include but are not limited to angle information of joints, relative position information of joints, etc. The more posture features that are compared, the higher the accuracy of the positioning state information of the determined target object.

[0098] S140. When the positioning state information of the target object is a positioning failure state, determine a position adjustment method for the target joint of the target object according to the relationship between the target joint position information of the target joint and the joint position information of the associated joint and the preset joint position information.

[0099] In a specific implementation, a position adjustment method of the target joint of the target object is determined based on the relationship between the target joint position information of the target joint and the joint position information of the associated joint and the preset joint position information, including: determining the adjustment direction of the target joint of the target object based on the difference between the actual angle information of the target joint and the preset angle information; determining the adjustment distance of the target joint of the target object based on the difference between the actual distance information of the target joint and the preset distance information; determining the position adjustment method of the target joint of the target object based on the adjustment direction and the adjustment distance.

[0100] Specifically, the difference between the actual angle information of the target joint and the preset angle information satisfies:

[0101]

[0102] The difference between the actual distance information of the target joint and the preset distance information satisfies:

[0103]

[0104] is the difference between the preset angle information and the actual angle information of the joint numbered x. The positive or negative value of determines the adjustment direction of the limb corresponding to the target joint. is the difference between the preset distance information and the actual distance information of the joint numbered x and the joint numbered y. The size of determines the limb adjustment distance corresponding to the target joint.

[0105] In the patient positioning adjustment method of the CT system provided by the embodiment of the present disclosure, firstly, according to the acquired three-dimensional image data of the target object, the joint position information of each joint of the target object is determined; then, according to the scanning parameters, the target joint and the associated joint are determined; and according to the relationship between the target joint position information of the target joint, the joint position information of the associated joint and the preset joint position information, the positioning state information of the target object is determined; finally, when the positioning state information of the target object is a positioning failure state, according to the relationship between the target joint position information of the target joint and the joint position information of the associated joint and the preset joint position information, the position adjustment mode of the target joint of the target object is determined. According to the joint position information of the target joint, the actual positioning angle and the actual positioning distance of the target joint can be determined, and then by comparing the actual positioning angle of the target joint with the preset positioning angle, and comparing the actual positioning distance of the target joint with the preset positioning distance, the position of the target joint is adjusted, the patient positioning process is optimized, the adjustment time is reduced, and the overall inspection efficiency and patient flow speed are improved. In addition, since the joint position information of each joint of the target object is determined based on automated visual image recognition technology, it is more accurate and further ensures the accuracy of the patient's positioning, thereby improving image quality and diagnostic effectiveness.

[0106] On the basis of the above embodiments, the patient positioning adjustment method in the CT scanning system provided in the embodiments of the present disclosure further includes:

[0107] According to the position adjustment method of the target joint of the target object, a screen demonstration video and voice prompt information are generated; the screen demonstration video is output to the display terminal, and the voice prompt information is output to the audio playback terminal, so as to prompt the target object to adjust the position of the target joint through the screen demonstration video and the voice prompt information.

By automatically generating correction suggestions, the system reduces reliance on manual intervention, improves operational efficiency, reduces human operational errors, reduces the need for communication between technicians or nurses and patients, reduces communication costs, and improves the smoothness of operations. In addition, by reducing direct contact between medical staff and patients, the probability of cross-infection is reduced, and the safety of the medical environment is improved.
