    摘要： An X-ray CT apparatus according to the embodiments has a rotation base that includes a plurality of units, including an X-ray generator that irradiates a subject with X-rays, and an X-ray detector that detects X-rays transmitted through the subject. It also has a pathway that communicates between the X-ray detector and at least one other unit excluding the X-ray generator and the X-ray detector. It also has an air supplier that supplies air in the other units to the X-ray detector via the pathway. It also has a temperature measuring part that measures the temperature in the X-ray detector. It also has a controller that performs control of the air supplier based on the measured result from the temperature measuring part.

    摘要： An X-ray CT apparatus according to an embodiment includes an X-ray detector and a collimator unit. The X-ray detector detects X-rays that have passed through a subject. The collimator unit eliminates scattered radiation from X-rays that are incident on the X-ray detector. The collimator unit includes a plurality of collimator modules, a supporter, and a fixing unit. The plurality of collimator modules each includes a plurality of first collimator plates arranged in a grid along a channel direction and a slice direction that are orthogonal to each other. The supporter supports the collimator modules such that the collimator modules are aligned in a plurality of straight lines along the channel direction and in a plurality of straight lines along the slice direction. The fixing unit is provided to the supporter and fixes positions of the collimator modules in the channel direction and the slice direction.

    摘要： An X-ray detector of an X-ray CT apparatus has a plurality of collimators, a plurality of scintillators, a plurality of photodiodes and a light guide. The plurality of collimators collimate an X-ray. The plurality of scintillators respectively emit fluorescence based on the X-ray from the plurality of collimators. The plurality of photodiodes respectively convert the fluorescence from the plurality of scintillators into the electric signal. The light guide has such a shape as to guide the fluorescence emitted from the plurality of scintillators respectively to the plurality of photodiodes while focusing the fluorescence toward the plurality of photodiodes.
