Direct measurement of CTDI(w) on helical CT scans

PURPOSE: Medical physics computed tomography (CT) practice involves measurements to determine CTDI(vol) on representative clinical CT protocols. In current practice the majority of CT exams employ helical scans. To determine CTDI(vol) for a helical scan, one measures CTDI(w) with an axial scan, then...
