Abstract
The present disclosure provides a sampling method and sampling apparatus of a scanning device. In at least one example, the sampling method comprises acquiring a ray attenuation variation at each of a plurality of scanning angles of the scanning device, determining a corrected sampling interval at each of the scanning angles of the scanning device by adjusting an initial sampling interval at each of the scanning angles of the scanning device according to the ray attenuation variation at each of scanning angles, and performing actual sampling according to the corrected sampling interval at each of the scanning angles of the scanning device.
Claims18
A sampling method of a scanning device, comprising:
- acquiring a ray attenuation variation at each of a plurality of scanning angles of the scanning device;
- determining a corrected sampling interval at each of the scanning angles of the scanning device by adjusting an initial sampling interval at each of the scanning angles of the scanning device according to the ray attenuation variation at each of the scanning angles;
- and
- performing actual sampling on a subject according to the corrected sampling interval at each of the scanning angles of the scanning device.
A sampling apparatus of a scanning device, the device comprising:
- a processor and a machine-readable storage medium,
- wherein by invoking and executing machine-executable instructions corresponding to a sampling control logic stored on the machine-readable storage medium, the processor is caused to:
- acquire a ray attenuation variation at each of a plurality of scanning angles of the scanning device;
- determine a corrected sampling interval at each of the scanning angles of the scanning device by adjusting an initial sampling interval at each of the scanning angles of the scanning device according to the ray attenuation variation at each of the scanning angles;
- and
- perform actual sampling on a subject according to the corrected sampling interval at each of the scanning angles of the scanning device.
