Signal playback time lag difference correction method for use in X-ray detector, involves subtracting output X-ray intensity reduction at different time periods, from output X-ray intensity at particular time period

摘要

The reduction of intensity of the output X-ray is measured at different time periods (n-1,n-2,n-3) and the intensity reduction is subtracted from the intensity of the output X-ray measured at a time period (n) for correcting the difference of the intensity between the input and output X-rays measured at the time period (n). Independent claims are also included for the following: (1) X-ray detector; and (2) computer tomography apparatus.
