Section 7.0 - Gantry Bearing Gap Inspection
Section 7.0 Gantry Bearing Gap Inspection
All CT systems require a gantry bearing gap inspection before starting electrical calibration.
All international gantries are shipped in a wooden shipping crate that should not be removed until
it arrives at the installation site. This shipping container is designed to reduce the risk of shipping
damage.
The back cover needs to be removed to gain access to the gantry bearing.
