Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a method and system for intelligent positioning of CT or PETCT patients. Background Art

[0002] PET (Positron Emission Tomography) stands for Positron Emission Tomography. It uses radionuclides that can emit positrons to label compounds that can participate in the blood flow or metabolic process of human tissues to obtain images of cross-sections, coronal sections, and sagittal sections of the human body.

[0003] CT (Computed Tomography) is a computer tomography scan that uses a precisely collimated X-ray beam and a highly sensitive detector to perform cross-sectional scans around a certain part of the human body one by one. It has the characteristics of fast scanning time and clear images, and can be used to detect a variety of diseases.

[0004] PETCT combines PET and CT organically. PETCT uses the same examination bed and an image workstation. PETCT has the functions of PET, CT and fusion of PET and CT images. The PETCT software system is mainly divided into CT system and PET system.

[0005] PETCT has improved the inspection efficiency and the detection method has also been significantly improved. It scans in a spiral form, the inspection time is relatively short, and the impact on the human body is reduced. At the same time, PETCT can understand the size and shape distribution of the corresponding organs and pathological tissues in three dimensions, which can provide an important scientific basis for the next step of disease treatment.

[0006] Whether it is CT or PETCT, the patient needs to be positioned and the designated part of the patient needs to be scanned. Usually, the doctor needs to enter the scanning room, determine the scanning direction and patient position according to the part to be scanned, and guide the patient to lie on the scanning bed in the correct posture. Then, the bed height is adjusted according to the system preset scanning bed height, and the scanning positioning phase is scanned to determine the patient's scanning range.

[0007] During the positioning process, the doctor needs to enter the scanning room to guide the patient's positioning, which increases the contact between the doctor and the patient and may pose risks such as disease transmission. When the patient lies on the scanning bed, due to incorrect posture, part of the body may extend beyond the scanning bed, causing the body to collide with the frame. In addition, since the bed height is based on the system preset height, each patient's condition is different, and the scanning part is different, it cannot be guaranteed that the center of the organ scanned each time is in the exact center of the frame, which affects the scanning accuracy and may have a certain impact on the imaging effect. When determining the scanning range, the doctor needs to scan a positioning image first. It is necessary to determine a larger scanning range based on the patient's body position and combined with the operation requirements to ensure that the part to be scanned is within the scanning range. Moreover, during the scanning process, the operating doctor cannot understand the patient's current condition in real time.

[0008] In summary, the following problems exist in the current positioning process:

[0009] 1. Doctors need to enter the scanning room to guide the patient's positioning, which increases the contact between doctors and patients and may pose risks such as disease transmission.

[0010] 2. When the patient is in an incorrect posture on the scanning bed, the limbs extending beyond the scanning bed may collide with the frame, posing a risk of collision.

[0011] 3. Unable to quickly find out that the patient's positioning direction is inconsistent with the scanning direction. If the patient's positioning direction is inconsistent with the scanning direction set by the system, the scanning part may not be scanned correctly, and the doctor may not be able to quickly find out.

[0012] 4. The height of the scanning bed uses the system preset height, which cannot guarantee that the center of the scanned part is in the exact center of the frame each time, so that the patient needs to bear more radiation dose and it will also affect the imaging effect.

[0013] 5. When scanning the positioning image, it is necessary to determine a relatively large scanning range based on the patient's body position and the operation requirements, so that the patient can be scanned for a longer length and receive more radiation dose.

[0014] 6. During the scanning process, the operating doctor cannot understand the patient’s current condition in real time and intuitively. Summary of the invention

[0063] Figure 1 A schematic flow chart of a method for intelligent positioning of CT or PETCT patients provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0064] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a clearer and more thorough understanding of the present invention and to be able to fully convey the scope of the present invention to those skilled in the art.

[0065] First, refer to Figure 1 This embodiment provides a CT or PETCT patient intelligent positioning method, including:

[0066] S1, obtaining system parameter configuration, and calibrating the depth camera disposed above the scanning bed to obtain calibration parameters.

[0067] S2, acquiring patient image information and depth information based on a depth camera.

[0068] S3, obtaining patient positioning voice instructions based on the patient's image information and depth information.

[0069] S4, determining a scanning protocol, wherein the scanning protocol includes a body part to be scanned.

[0070] S5, determining a scanning start position and a scanning end position according to the body part to be scanned, the patient's image information, the depth information, the system parameters and the calibration parameters.

[0071] S6, confirming the thickness of the body part to be scanned based on the depth camera, system parameters and calibration parameters.

[0072] S7, adjust the scanning bed so that the center of the body part to be scanned is at the same height as the center of the gantry.

[0073] S8, reacquiring the patient's image information and depth information.

[0074] S9, when it is determined that the patient is at risk of collision based on the re-acquired patient image information and depth information, an early warning reminder is issued.

[0075] S10, intelligent positioning is completed and scanning begins.

[0076] The present embodiment provides a CT or PETCT patient intelligent positioning method, which can understand the patient's condition in real time. Reduce the radiation dose received by the patient. Automatically determine the starting and ending positions of the scanning area. After the doctor selects the scanning area, the system will automatically identify the area to be scanned and more accurately determine the starting and ending positions of the scan. The scanning area is positioned more accurately, which reduces unnecessary area scanning, thereby reducing the radiation dose received by the patient. The imaging effect is better. The system calculates the body thickness of the area to be scanned and automatically adjusts the bed height so that the center of the area to be scanned is at the same height as the center of the rack, making the imaging effect of the image data more accurate.

[0077] The system uses image recognition to check whether the patient's positioning direction is consistent with the scanning direction. If not, an early warning notification will be issued. Early warning of collision between the patient's limbs and the rack to avoid injuries caused by collision between the patient's limbs and the rack. The system issues a patient position collision warning based on the camera image information and depth information. When a collision risk between the patient's limbs and the rack is found, an early warning reminder will be issued. The risk of collision between the patient's limbs and the rack is reduced, and the risk of incorrect scanning positioning direction is reduced.

[0078] Optionally, calibrating a depth camera disposed above the scanning bed includes:

[0079] The depth camera set above the scanning bed is calibrated in parallel, height and level.

[0080] Optionally, during the parallel calibration process, the position and angle of the depth camera are adjusted so that the plane of the depth camera is parallel to the scanning bed and the ground;

[0081] Height calibration records the vertical distance between the scanning bed and the depth camera, and associates the height information of the scanning bed with the depth camera coordinate system to provide a reference for positioning;

[0082] Horizontal calibration relates the position of the scanning bed to the depth camera coordinate system, providing a reference for positioning.

[0083] By ensuring the correct geometric relationship between the depth camera and the scanning bed, errors caused by inaccurate position can be reduced and the spatial accuracy of the scan results can be improved. The calibration process eliminates scanning errors that may be caused by position deviation and angle misalignment of the depth camera, ensuring that the depth information of each position can be accurately captured. The calibration of the depth camera helps to better integrate the depth data with the scan data in the future, thereby providing a more accurate basis for diagnosis.

[0084] Optionally, obtaining a patient positioning voice instruction based on the patient image information and depth information includes:

[0085] Determine the patient's position based on the patient's image information and depth information combined with a coordinate system of a depth camera;

[0086] Get voice instructions for patient positioning based on patient position.

[0087] By installing voice communication equipment, doctors and patients can communicate through voice communication equipment. Doctors can issue voice instructions for positioning through voice communication equipment to guide patients to position themselves. In addition, if there is a risk of collision with the patient, the doctor can use the image information provided by the depth camera to guide the patient to reposition through the voice communication equipment to avoid collision.

[0088] Doctors can view the patient's image in real time during the entire scanning process. Doctors and patients can communicate in real time. Doctors can guide patients to complete positioning and scanning instructions, and patients can communicate with doctors in real time if they have questions. This reduces the risk of disease transmission. Doctors can communicate with patients in real time and provide remote guidance on patient positioning by viewing the images in the scanning room without entering the operating room.

[0089] Optionally, the scanning protocol further includes: scanning parameters and tracer types.

[0090] Optionally, determining a scanning start position and a scanning end position according to a body part to be scanned, patient image information, depth information, system parameters and calibration parameters includes:

[0091] According to the body part to be scanned and the patient's image information, the coordinates of the body part to be scanned in the image coordinate system are determined by image recognition;

[0092] According to the depth camera parameters and the depth information, the coordinates of the body part to be scanned in the image coordinate system are converted into the coordinates of the body part to be scanned in the camera coordinate system;

[0093] According to the calibration parameters and the system parameters, the coordinates of the body part to be scanned in the camera coordinate system are converted into the coordinates of the body part to be scanned in the scanning bed coordinate system;

[0094] The scanning start position and the scanning end position are determined according to the coordinates of the body part to be scanned in the scanning bed coordinate system.

[0095] Doctors can view the start and end positions of the scan in the real-time image, or manually drag and adjust them.

[0096] Optionally, determining the thickness of the body part to be scanned based on the depth camera, system parameters and calibration parameters includes:

[0097] The distance from the depth camera to the ground is calculated based on the vertical distance between the scanning bed and the depth camera and the height of the scanning bed;

[0098] The thickness d of the body part to be scanned is calculated according to the following formula:

[0099] H1-H2-H3=d;

[0100] Among them, H1 is the distance from the depth camera to the ground, H2 is the height of the scanning bed, and H3 is the distance from the depth camera to the body part.

[0101] The system parameters set the offset of the thickness of the body part to be scanned. Because the depth camera has a certain accuracy error, a certain offset can be set to correct the deviation.

[0102] The following is a specific embodiment to further illustrate a CT or PETCT patient intelligent positioning method of the present application.

[0103] Step 1: Install the depth camera and voice communication equipment. Install the depth camera and voice communication equipment in front of the rack, just above the scanning bed. Make sure the left and right sides of the camera are centered on the center line of the equipment to facilitate subsequent camera adjustment and calibration.

[0104] Step 2: Set system parameters and calibrate the camera. First, set the system parameters, calibration accuracy, and scanning range offset parameters. Then follow the calibration process to perform parallel calibration, height calibration, and horizontal calibration. During the parallel calibration process, you can adjust the camera position and angle so that the camera plane is parallel to the scanning bed and the ground. The height calibration will record the vertical distance between the scanning bed and the camera. Through horizontal calibration, the position of the scanning bed is associated with the camera coordinate system to provide a basis for automatic positioning.

[0105] Step 3: The doctor remotely guides the patient to position the patient. During this process, the doctor communicates with the patient in real time through the real-time camera image to guide the patient to complete the positioning.

[0106] Step 4: Confirm the scan area and select the scan protocol. The doctor selects the appropriate scan protocol based on the examination the patient needs.

[0107] Step 5: The system identifies the part to be scanned and automatically calculates the scan start and end positions. The bed height is automatically calculated based on the depth information of the part to be scanned. The patient's positioning direction is checked. If it is inconsistent with the scanning direction, an early warning is issued. At the same time, the system checks the patient's limb collisions and issues an early warning if there is a risk of collision.

[0108] Step 6: After the intelligent positioning is completed, the scan begins. The doctor can view the status of the patient and the device during the scan and understand the situation in the scan room through the real-time camera image.
