X-RAY CT APPARATUS AND X-RAY DETECTOR |
摘要 |
An X-ray computer tomography (CT) apparatus according to an embodiment includes an X-ray source, an X-ray detector, and generating circuitry. The X-ray source radiates X-rays. The X-ray detector includes a scintillator including a first region close to the X-ray source and a second region distant from the X-ray source, an optical sensor that detects scintillator light obtained by converting the X-rays radiated from the X-ray source with the scintillator, and a variable layer that is provided in the scintillator and switchable between a first state in which the variable layer transmits the scintillator light between the first region and the second region and a second state in which the variable layer does not transmit the scintillator light between the first region and the second region. The generating circuitry generates a CT image based on a signal output from the X-ray detector. |

1. An X-ray computer tomography (CT) apparatus comprising:
an X-ray source configured to radiate X-rays; an X-ray detector including a scintillator including a first region close to the X-ray source and a second region distant from the X-ray source, an optical sensor configured to detect scintillator light obtained by converting the X-rays radiated from the X-ray source with the scintillator, and a variable layer that is provided in the scintillator and switchable between a first state in which the variable layer transmits the scintillator light between the first region and the second region and a second state in which the variable layer does not transmit the scintillator light between the first region and the second region; and generating circuitry configured to generate a CT image based on a signal output from the X-ray detector. |
