Abstract:
     It is a method to realize the measurement and compensation focus with several signal paths and its focus compensation X ray CT apparatus. Before scanning, it uses X-ray to scan two lines of multiple-signal detector light surfaces through hole parallel move of the collimation device. It figures the focus outline position according to the main image position and figures the position of inner size of hole with same position with the main image outline under the T signal path serving as aim value to adjust the collimation device.
