Abstract: A radiation image acquiring system is provided. An X-ray image acquiring system irradiates X-rays to a subject from an X-ray source, and detects X-rays transmitted through the subject. The X-ray image acquiring system includes a first detector for detecting X-rays that are transmitted through the subject to generate first image data, a second detector arranged in parallel to the first detector with a dead zone region sandwiched therebetween, for detecting X-rays that are transmitted through the subject to generate second image data, and a timing control section for controlling detection timing of the second detector based on a dead zone width of the dead zone region so that first image data to be generated by the first detector and second image data to be generated by the second detector mutually correspond.

Abstract: In an X-ray line sensor 1, a scintillator layer 24 that absorbs X-rays in a low-energy range and emits light and a scintillator layer 26 that absorbs X-rays in a high-energy range and emits light are brought in contact with each other, and further, the thickness of the scintillator layer 24 on the front side is thinner than that of the scintillator layer 26 on the rear side. These make the amount of mismatch small between a light emitting position P1 in the scintillator layer 24 and a light emitting position P2 in the scintillator layer 26 to X-rays in the low-energy range and X-rays in the high-energy range entered at the same angle from the front side, so that at this time, light emitted by the scintillator layer 24 and light emitted by the scintillator layer 26 are detected by a photo-detecting section 16 and a photo-detecting section 23 facing each other. Thus, mismatch between an X-ray transmission image in the low-energy range and an X-ray transmission image in the high-energy range obtained simultaneously can be prevented.
