Patent ID: 6925144

Claim:
An X-ray digital tomographic image taking apparatus comprising: an X-ray generation unit for emitting X-rays; a first transfer unit for changing the emission direction of X-rays emitted by the X-ray generation unit and transferring the X-ray generation unit; a solid state image sensing unit consisting of a plurality of solid state image sensing elements for converting X-rays to electric signals; a second transfer unit for transferring the solid state image sensing unit; and a control unit for controlling the first transfer unit and second transfer unit so that X-rays emitted from said X-ray generation unit are emitted to predetermined coordinates on the photoreceiving surface of said solid state image sensing unit, and controlling the emissions of the X-ray generation unit and the drive of the solid state image sensing unit, wherein said control unit divides the course along which said X-ray generation unit or solid state image sensing unit is moving into a plurality of sections and controls said X-ray generation unit so that the quality of said X-rays differs between neighboring sections.
