Times Cited Count:0 Percentile:0.01(Nuclear Science & Technology)A photon detector for unfolding X-ray energy distribution has been previously reported. Simulation studies on the unfolding method for this detector are discussed for diagnostic X-rays and mixed-source rays of Cs/Co. Response functions for diverse diagnostic X-rays are almost indistinguishable and an unfolding using error reduction method is not sufficiently worked. The spectrum surveillance method is effective in this case. However, a simple error reduction method is useful for mixed rays. For both techniques, the neural network method is promising.

X-ray energy spectrum measurement in a short time is necessary for CT picture measurement with energy difference method. For this purpose, current mode detector, which is applied X-ray detectors used with current mode and can obtain rough X-ray energy spectrum, is examined. X-ray detector array is used as the electric current mode detector and unfolding of output of the detector to energy spectrum is studied. Furthermore, optimized detector array constitution is also discussed.
