Document Type and Number:
Japanese Patent JP7073091
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To lower visibility of the inside of a gantry enclosure, while retaining the visibility of visible light exited from a projector.SOLUTION: The X-ray computed tomography apparatus according to one embodiment includes a gantry device for performing X-ray CT imaging, and a processing unit for controlling the gantry device. The gantry device includes: a gantry enclosure having an opening through which a subject is inserted and equipped with an imaging mechanism of the X-ray CT imaging; at least one projector provided in the gantry enclosure and exiting visible light; and a permeable membrane mounted on an inner wall part facing the opening out of the gantry enclosure and transmitting the visible light exited from the projector. The permeable membrane has such a color as to belong to a wavelength band transmitting the visible light, and preventing the inside of the gantry enclosure from being easily viewed from the outside, the wavelength band excluding a wavelength to which the visible light belongs.SELECTED DRAWING: Figure 1
