An X-ray image acquiring system capable of improving the detection accuracy of a foreign substance contained in a subject is provided. An X-ray image acquiring system 1 irradiates X-rays to a subject S having a predetermined thickness W from an X-ray source, and detects X-rays transmitted through the subject S in a plurality of energy ranges. The X-ray image acquiring system 1 includes a low-energy detector 32 for detecting, in a low-energy range, X-rays having been transmitted through a region R1 extending in a thickness direction within the subject S, a high-energy detector 42 for detecting, in a high-energy range, X-rays having been transmitted through a region R2 extending in a thickness direction within the subject S, and a timing control section 50 for controlling detection timing of X-rays in the low-energy detector 32 and the high-energy detector 42 so that an inspecting region E located at a predetermined site within the subject S is included in the region R1 and the region R2.
