Evaluation of Patient Doses from Verification Techniques in Image-Guided Radiotherapy (IGRT)

摘要

The purpose of this work was an evaluation of organ doses and effective doses from kilovoltage (kV) Cone-beam CT (CBCT) scans and from pairs of orthogonal kV image projections for two different treatment sites (a head and a pelvis). Measurements of organ doses were performed in an anthropomorphic Rando phantom by means of thermoluminescent dosimeters (TLDs). Irradiations were performed using On-Board Imager (OBI) and X-ray Volume Imaging (XVI) systems.
