Objective: This study is the first investigation on computed tomography (CT) unit in Guyana at the Cancer Institute of Guyana (CIG), aimed at performing an audit on the radiation dose estimated by the GE LightSpeed QXi
CT unit for common computed tomography examinations.
Method: A RaySafe X2 CT calibration detector were used to obtained measurements for common CT
examinations (head, neck, chest, abdomen, pelvis, upper extremity and lower extremity) done in free air as the
control (36 data) and also with patients (35 data). Patient’s measurement was limited to the head, chest, abdomen
and pelvis CT examinations. Exposure/electro-technical parameters and dose metrics (CTDIvol, DLP) were recorded
and the k-coefficient conversion factor established by National Radiology Protection Board (NRPB) was used to
