SYSTEMS AND METHODS FOR SELECTABLE DETECTOR CONFIGURATIONS

摘要

An X-ray detector includes a light sensor configured to receive light energy from a scintillator receiving X-rays. The light sensor includes a grid of pixels having a light reception surface oriented toward the scintillator and configured to receive light from the scintillator. Each pixel includes a diode assembly, a control assembly and a capacitor assembly. The diode assembly is disposed on the light reception surface and is configured to produce electric charge responsive to light received by the diode assembly. The diode assembly includes plural diodes selectably configurable in plural combinations, wherein an amount of the electric charge produced by the diode assembly varies based on a selection of diode combination. The control assembly is operably connected to the diode assembly and configured to selectably configure the diodes. The capacitor assembly is operably connected to the diode assembly and configured to receive and store the electric charge from the diode assembly.
