A solid-state image sensor 31, which has a two-dimensional matrix of a plurality of pixels used to sense the two-dimensional spatial distribution of radioactive rays, light rays, electrons, ions, or the like, is provided with an aperture 34 that extends through a substrate 33b of an image sensing unit 33 on which the pixels are arranged, and a signal transfer path that connects signal transfer electrodes 33d for reading images of the respective pixels kept clear of the aperture 34. Furthermore, the image sensing unit 33 is divided into at least two regions by a boundary including the aperture 34, and these regions have individual signal read registers. With this structure, the image sensor serves as both an image sensor for sensing the two-dimensional distribution of radiation or the like, and an aperture for passing such radiation. <IMAGE> |
