PURPOSE To determine physician radiation exposure when using partial-angle computed tomography (CT) fluoroscopy (PACT) vs conventional full-rotation CT and whether there is an optimal tube/detector position at which physician dose is minimized. MATER

Primary Standard Dosimetry Laboratories establish the standards of absorbed dose to water (ADW) using calorimetry. This is because calorimetry is the most direct method to account for the energy imparted to matter by radiation. The traditional calori
