Radiographic system

Abstract

A radiographic system comprises two radiation detectors (20 (20A, 20B)) that capture radiological images. Image information representing the radiological images taken by the radiation detectors (20A, 20B) can be individually read, and each sensor unit (13) constituting at least one of the radiation detectors (20) is configured to include an organic photoelectric conversion material that generates an electric charge by receiving light. The radiographic equipment is thus able to capture a variety of radiological images.

Description

technical field [0001] The present invention relates to a radiation imaging device. Background technique [0002] In recent years, radiation detectors such as FPDs (Flat Panel Detectors) capable of directly converting radiation such as X-rays into digital data by disposing a radiation sensitive layer on a TFT (Thin Film Transistor) active matrix substrate have been put into practical use. Compared with the conventional radiographic apparatus using X-ray film or imaging plate, the radiographic apparatus using this radiation detector has fluoroscopic imaging ( Advantages of moving image shooting). [0003] As such radiation detectors, various types have been proposed. For example, there is an indirect conversion method in which radiation is first converted into light by a scintillator such as CsI:Tl or GOS (Gd2O2S:Tb), and then the converted light is converted into electric charge by a sensor such as a photodiode and stored. The radiation imaging apparatus reads the electri...

But the thicker the scintillator, the further away the light from the scintillator is from the substrate, so the sharpness of the resulting image becomes less
