X-RAY COMPUTED TOMOGRAPHY APPARATUS

摘要

An X-ray tube and An X-ray detector are mounted on a gantry rotating unit. A gantry fixing unit supports the gantry rotating unit so as to allow it to rotate about a rotation axis. A cover covers the gantry rotating unit and the gantry fixing unit. At least one outlet for discharging air inside the gantry is formed in the cover at a position shifted from an area squaring facing the outer circumference of the gantry rotating unit along the rotation axis. At least one cooling fan is mounted on the gantry fixing unit so as to be located near at least one outlet, and sends air to at least one outlet.

主权项

1. An X-ray computed tomography apparatus comprising:
an X-ray tube configured to generate X-rays; an X-ray detector configured to detect X-rays generated from the X-ray tube; a rotating unit on which the X-ray tube and the X-ray detector are mounted; a fixing unit provided with the rotating unit along a rotation axis direction and configured to support the rotating unit so as to allow the rotating unit to rotate about the rotation axis; a cover which covers the rotating unit and the fixing unit and has at least one outlet for discharging inside air which is formed at a position shifted from an area along the rotation axis, the position squarely faces an outer circumference of the rotating unit; and at least one exhaust fan mounted on the fixing unit so as to be located near the at least one outlet and configured to send air to the at least one outlet.
