Abstract

Volumetric discrepancies between cone-beam computed tomography (CBCT) and planning CT image sets were investigated for both prone and supine breast radiotherapy. A phantom study was performed in order to examine the artefacts' dependency on CBCT acquisition parameters and to minimize their effect on patient set-up accuracy.
