APPARATUS, DETECTOR, AND METHOD FOR APPLYING A PIXEL BY PIXEL BIAS ON DEMAND IN ENERGY DISCRIMINATING COMPUTED TOMOGRAPHY (CT) IMAGING

摘要

A Computed Tomography (CT) method, apparatus, and detector, which includes a plurality of energy-discriminating detector elements configured to capture incident X-ray photons emitted from an X-ray source. Each of the plurality of energy-discriminating detector elements of the detector is configured to have a respective bias voltage individually switched ON or OFF, based on a signal received from a controller.
