Outline of Final Research Achievements |
We performed fundamental experiments concerning zero-dark-counting Mcps-range X-ray photon detectors of LSO-MPPC and YAP(Ce)-MPPC. In these experiments, the count rate was increased, and the special resolutions were improved. Next, we developed a dual-energy (DE) photon counter to select two different energy ranges, and K-edge CT using iodine (I) and gadolinium (Gd) media was performed. The quad-energy (QE) counter was developed to perform QE-CT, and four different energy tomograms were obtained simultaneously. Finally, high-spatial-resolution DE-CT was accomplished using a CdTe-array detector with a spatial resolution of 0.1 mm, and high-spatial-resolution I-K-edge CT was performed.
