X-ray-tomographic imaging apparatus and method with non-destructive read-out solid-state image pickup device

摘要

An X-ray-tomographic imaging apparatus for obtaining image data on a predetermined tomographic section of a subject with efficiency and effectiveness by using a plurality of X-ray projection images achieved by a plurality of X-rays that is made incident on the tomographic section from different directions is provided. The X-ray-tomographic imaging apparatus comprises a solid-state image pickup unit (13) that can convert each of the X-ray projection images to a signal and read the signal by a non-destructive reading method and a control unit (14) making the solid-state image pickup unit accumulate the signals of the X-ray projection images and read the signals by the non-destructive reading method during the signal accumulation.
