Mathematical estimation and in vivo dose measurement for cone-beam computed tomography on prostate cancer patients.

Background And Purpose: Cone-beam computed tomography (CBCT) increases the doses on normal tissues. Our study sought to develop a mathematical model that would provide an estimate of and verify in vivo rectal dose from CBCT in prostate cancer patients.

Materials And Methods: Thermoluminescent dosimeters (TLDs) and Rando phantoms were used to measure doses to the pelvic region.
