Provided is an X-ray detector having enhanced X-ray sensitivity, which enables dual energy imaging having high diagnostic performance. This X-ray detector (1) includes: scintillator elements (15) which are partitioned by light blocking walls (17) and which convert low-energy X-rays to light; and scintillator elements (19) which are partitioned by light blocking walls (21) and which convert high-energy X-rays to light. When seen from the direction of incidence of the X-rays, the positional pattern of the light blocking walls (17) and that of the light blocking walls (21) are configured so as not to be in alignment with each other. Accordingly, the X-rays incident on the X-ray detector (1) are converted to light by at least either one of the scintillator elements and are finally outputted as X-ray detection signals. That is, even when the light blocking walls are formed in the X-ray detector (1), an area where X-rays cannot be detected does not exist. Therefore, this configuration is capable of improving the X-ray sensitivity of the X-rays detector while increasing the resolution of an X-ray image due to the light blocking walls. |
