PHYSICAL VALIDATION OF A MONTE CARLO-BASED PHANTOM-DERIVED APPROACH TO COMPUTED TOMOGRAPHY ORGAN DOSIMETRY UNDER TUBE CURRENT MODULATION

摘要

Purpose:To physically validate the accuracy of a Monte Carlo-based, phantom-derived methodology for computed tomography (CT) dosimetry that utilizes organ doses from pre-computed axial scans and that accounts for tube current modulation (TCM).
