Evaluation of a mobile C-arm cone-beam CT in interstitial high-dose-rate prostate brachytherapy treatment planning.

ABSTRACT:

Introduction

The aim of this study was to evaluate the suitability of using cone-beam computed tomography (CBCT) obtained with a mobile C-arm X-ray fluoroscopy unit as a single modality for planning of high-dose-rate (HDR) prostate brachytherapy treatments.

Methods

The feasibility of using CBCT images obtained using a Siemens Arcadis Orbic 3D mobile C-arm was evaluated. A retrospective clinical study was undertaken of six participants undergoing HDR prostate brachytherapy. Plans generated using images from a Toshiba Aquilion One LB CT were compared with those generated using CBCT images. After rigid spatial registration, the plans were compared based on various parameters such as dose-volume histograms, overlap quantities and metrics, and dose constraints.
