Abstract
An imaging method is provided. In an example, the imaging method includes a first X-ray image including a ROI of a subject is taken by an image capturing device, a position of the ROI in the first X-ray image is determined, a moving distance and a moving direction for a positioning system is determined based on the position of the ROI in the first X-ray image, and the positioning system is capable of being moved to adjust a positional relationship between the image capturing device and the subject, the positioning system is moved based on the moving distance and the moving direction, and a second X-ray image including the ROI is taken by the image capturing device, and the ROI is located in a center position of the second X-ray image.
Claims14
An imaging method, comprising:
- generating a first X-ray image including a region of interest (ROI) of a subject by an image capturing device, the image capturing device comprising a transmitter configured to emit X-rays to the subject and a receiver configured to detect X-rays passing through the subject, the ROI of the subject indicating a detected part of the subject;
- determining a distance and a positional direction between a center point of the first X-ray image and a center point of the ROI in the first X-ray image as a center point positional relationship;
- determining a moving distance and a moving direction for a positioning system based on the center point positional relationship, wherein the positioning system is configured to be moved to adjust a positional relationship between the image capturing device and the subject;
- moving the positioning system based on the moving distance and the moving direction;
- and
- taking a second X-ray image including the ROI by the image capturing device, wherein the ROI is located in a center position of the second X-ray image.
An imaging system, comprising:
- an image capturing device, configured to generate a first X-ray image including a ROI of a subject and a second X-ray image including the ROI, wherein the ROI is located at a center position of the second X-ray image, the image capturing device comprising a transmitter configured to emit X-rays to the subject and a receiver configured to detect X-rays passing through the subject, the ROI of the subject indicating a detected part of the subject;
- a positioning system configured to be moved to adjust a position of the ROI in the first X-ray image;
- a processing device, configured to:
- determine a distance and a positional direction between a center point of the first X-ray image and a center point of the ROI in the first X-ray image as a center point positional relationship, and
- determine a moving distance and a moving direction for a positioning system based on the center point positional relationship;
- and
- a controlling device, configured to move the positioning system based on the moving distance and the moving direction.
