RADIATION DETECTION DEVICE, RADIATION IMAGE ACQUISITION SYSTEM, RADIATION DETECTION SYSTEM, AND RADIATION DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radiation image acquisition system that improves detection accuracy of a foreign matter and the like in a target object.SOLUTION: An X-ray image acquisition system irradiates a subject S with an X-ray from an X-ray source and detects the X-ray in a plurality of energy ranges passing through the subject S. The X-ray image acquisition system is configured to comprise: a low energy detector 32 that detects the X-ray in a low energy range passing through the subject S, and generates low energy image data; a high energy detector 42 that detects the X-ray in a high energy range passing through the subject S arranged in parallel with the low energy detector 32 with a dead zone area sandwiched, and generates high energy image data; and a timing control part 50 that controls a detection timing of the high energy detector 42 on the basis of a dead zone width of the dead zone area such that the low energy image data generated by the low energy detector 32 and the high energy image data generated by the high energy detector 42 correspond to each other.
