A comparison of methods to estimate organ doses in CT when utilizing approximations to the tube current modulation function

Purpose: Most methods to estimate patient dose from computed tomography (CT) exams have been developed based on fixed tube current scans. However, in current clinical practice, many CT exams are performed using tube current modulation (TCM). Detailed information about the TCM function is difficult t...
