Computed tomography system
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 11 a to 11 d 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.
1. A computed tomography system comprising:
a radiation irradiation system that provides a radiation that is a beam having a region of irradiation spreading radially in a direction of irradiation;
a turn table system on which a testing object is placed, said turn table system comprising one large turn table and a plurality of small turn tables, wherein the large and small turn tables are selectively used; and
a radiation detection system that detects the radiation having penetrated the testing object, the radiation being applied to the testing object being rotated using the turn table system, the radiation detection system detecting the radiation in the irradiation to acquire radiation penetration data for image reconstruction.
2. The computed tomography system according to claim 1 , wherein the plurality of small turn tables are installed on the large turn table, as required, via attachment portions provided on the large turn table.
3. The computed tomography system according to claim 1 , wherein the plurality of small turn tables are arranged in the region of irradiation with the radiation beam, and the large turn table is installed above the plurality of small turn tables, as required, via an attachment portion provided in the region of irradiation with the radiation beam.
