Photon-counting x-ray computed radiography system utilizing a cadmium telluride detector

The construction of a photon-counting x-ray computed tomography(CT) system utilizing a cadmium telluride(CdTe) detector is described. The CT system is of the first generation type and consists of an x-ray generator, a turn table, a translation table, a motor drive unit, a CdTe detector, two amplifiers, multi-channel analyzer(MCA), and a personal computer(PC). Tomography was performed by the repetition of the translation and rotation of an object. Penetrating x-ray spectra from an object are measured by a spectrometer utilizing a CdTe detector and a MCA, and both the photon energy and the energy width are determined by the MCA

X-ray computed tomography system utilizing a cadmium telluride detector

A simple x-ray computed tomography(CT) system utilizing a cadmium telluride detector is described. The CT system is of the first generation type and consists of an x-ray generator, a turn table, a translation table, a motor drive unit, a cadmium telluride detector, an interface unit for the detector, and a personal computer(PC). Tomography was performed by the repetition of the translation and rotation of an object. The maximum values of the tube voltage and the tube current were 110kV and 2.0mA, respectively. Tomography was performed at a tube voltage of 60kV and a current of 1.5mA
