Estimating patient dose from CT exams that use automatic exposure control: Development and validation of methods to accurately estimate tube current values

PURPOSE: The vast majority of body CT exams are performed with automatic exposure control (AEC), which adapts the mean tube current to the patient size and modulates the tube current either angularly, longitudinally or both. However, most radiation dose estimation tools are based on fixed tube curre...
