Quantum dot digital radiographic detection system

摘要

A digital quantum dot radiographic detection system described herein includes: a scintillation subsystem and a semiconductor visible light detection subsystem (including a plurality of quantum dot image sensors). In a first preferred digital quantum dot radiographic detection system, the plurality of quantum dot image sensors is in substantially direct contact with the scintillation subsystem. In a second preferred digital quantum dot radiographic detection system, the scintillation subsystem has a plurality of discrete scintillation packets, at least one of the discrete scintillation packets communicating with at least one of the quantum dot image sensors.
