The present invention provides a computed tomography system that only requires rotational scans for image pickup, the system enabling images of a plurality of testing objects to be simultaneously picked up without increasing the volume of noise or the scale of the system, thus enabling high-quality tomographic images to be efficiently picked up. In the computed tomography system, a plurality of turn tables 11a to 11d are provided in a region of irradiation with X-ray beams emitted by an X-ray irradiation system. Testing objects Ma to Md are placed on the respective turn tables. Images of the plurality of testing objects can be simultaneously picked up by irradiation with X-ray beams. This enables precise image pickup to be efficiently achieved without increasing the size of the scale.
