Abstract: A gantry housing 20 comprises a front cover 30, a main cover 40, a rear cover 50, and a scan window 60. The scan window 60 has a PolyCarbonate (PC) sheet 61, and elastic members 62 and 63. The front cover 30 has a receiving portion 32 in which the elastic member 62 is disposed, and a reinforcing portion 33 for reducing deformation of the PC sheet 61; the rear cover 50 has a receiving portion 52 in which the elastic member 63 is disposed, and a reinforcing portion 53 for reducing deformation of the PC sheet 61.

Abstract: The present invention relates to a gantry of a CT scanning device comprising: a first housing having a first bore; a second housing having a second bore, disposed opposite to the first housing, wherein there is a gap between the first bore and the second bore, as a ray scanning bore; a scan window assembly comprising an annular window body having an inner surface and an outer surface, the scan window assembly being engaging-locked with the first housing and the second housing and sealing and covering the ray scanning bore. In this way, the engaging-lock can restrict deformation of the annular window body when an external force is applied on the scan window assembly, and the sealing can prevent liquid in the first and second housing from leaking out and prevent liquid inside the scan window assembly from leaking into the first and second housing.
