Abstract:
1. An X-ray inspection system used for a dental application, comprising: a solid-state image pickup apparatus; and an X-ray generator, wherein the X-ray output from the X-ray generator transmits through an inspection object to form an X-ray image, and the X-ray image is picked up by the solid-state image pickup apparatus to inspect the inspection object, where M and N are each an integer not less than 2, M wherein the solid-state image pickup apparatus comprises: a photodetecting section where M×N pixel units P a readout wiring L a signal readout section including N holding circuits H a controlling section that controls an opening and closing operation of the readout switch of each of the M×N pixel units P the controlling section when in a first imaging mode, makes a voltage value according to an amount of charge generated in the photodiode of each of the M×N pixel units P when in a second imaging mode, makes a voltage value according to an amount of charge generated in the photodiode of each pixel unit P wherein the solid-state image pickup apparatus and the X-ray generator are rotatable around the inspection object while facing each other, or the image pickup apparatus is linearly movable with respect to the inspection object, wherein a direction of the rotation movement or a direction of the linear movement is perpendicular to a longitudinal direction of the specific range in the photodetecting section in the second imaging mode.
