Abstract
PURPOSE: To obtain a recomposed picture free from the noise by analyzing the collected X-ray absorption data through the computer with addition of correction based on the calibration data.
CONSTITUTION: Utilizing the impulse exposure of the X-ray beam, the reference signal of the reference voltage of the like is collected by data collecting device 4 for calibration stabilizing power source 31 during discontinuation of the exposure of the X-ray beam. Thus, the data of the reference signal and the detection data of X-ray detecting device 3 are collected alternately and then memorized. And a correction is given to the detection data using the fluctuation of the reference signal data as the correction value. As a result, the detection data in which the sensitivity fluctuation is completely corrected for device 4 can be obtained, thus ensuring the recomposition of the picture with no linear noise. Accordingly, a correct diagnosis becomes possible.
