Abstract： |
The invention is concerned with the CT image rebuilding system based on support field, the characteristic is: uses X ray source and radial detector to get the projection data of the object, uses outline testing equipment to get the support field of the object, gets CT rebuild image by the computer CT image rebuild arithmetic. The invention is less projection data, fast operation, and lower radiation dose. |
