Abstract

Official abstract text for this publication.

A measurement area selection circuit has an irradiation field determination unit, an object area determination unit, and a measurement area determination unit. The irradiation field determination unit determines an irradiation field of an imaging surface of an FPD. The object area determination unit determines an object area from a comparison result between a first expected received dose of a directly exposed area and dose detection signals of detection pixels situated in the irradiation field. The measurement area determination unit determines a measurement area, which corresponds to a region of interest, from a comparison result between a second expected received dose of the measurement area and the dose detection signals of the detection pixels situated in the irradiation area and the object area. The dose detection signals of the detection pixels situated in the measurement area are used for AEC.

First claim

Opening claim text (preview).

What is claimed is: 1. A radiation imaging system including an x-ray or γ-ray radiation source for emitting x-ray or γ-ray radiation to an object, and an x-ray or γ-ray radiation image detecting device having an x-ray or γ-ray detection panel formed with an imaging surface for imaging a radiographic image of said object, said imaging surface having an array of a plurality of pixels each for accumulating electric charge in accordance with a received dose of said radiation emitted fr…
