摘要
The method involves carrying out an off-line calibration in the first instance. Calibration parameters are altered so that the reconstructed volumes have very sharp edges and hence have high frequencies. The degrees of freedom of the projection imaging are limited to one or more of the extrinsic parameters and the others are accepted as constants.
