Dual-energy X-ray computed tomography scanner using an energy-selecting device and a cadmium telluride detector

Dual-energy photon counting was performed using an energy-selecting device (ESD) and a cadmium telluride detector. The ESD is used to determine a low-energy range for computed tomography (CT) and consists of two comparators and a microcomputer (MC). The two threshold energies are determined using lo...
