Volume delineation quality assurance (QA) is particularly important in clinical trial settings where consistent protocol implementation is required, as outcomes will affect future as well current patients. Currently, where feasible, this is conducted manually, which is time consuming and resource intensive. Although previous studies mostly focused on automating delineation QA on CT, magnetic resonance imaging (MRI) is being increasingly used in radiotherapy treatment. In this work, we propose to...

INTRODUCTION: Variation in target volume delineation from clinical trial protocols has been shown to contribute to poorer patient outcomes. A clinical trial quality assurance framework can support compliance with trial protocol. Results of the TROG 08.03 RAVES benchmarking exercise considering variation from protocol, inter-observer variability and impact on dosimetry are reported in this paper. METHODS: Clinicians were required to contour and plan a benchmarking case according to trial protocol...

Introduction We investigated the endorectal balloon (ERB) as a method to improve post-prostatectomy clinical target volume (CTV) stability. Methods Seventy cone-beam CT (CBCT) obtained during radiotherapy treatment from seven patients treated with an ERB and 68 CBCT from seven patients treated without an ERB were contoured according to published guidelines. CTV was subdivided into superior and inferior CTV; whole rectal volume was subdivided into superior and inferior rectum and anal volume. Con...

Abstract Purpose To perform a comparative study assessing potential benefits of endorectal-balloons (ERB) in post-prostatectomy patients. Method and materials Ten retrospective post-prostatectomy patients treated without ERB and ten prospective patients treated with the ERB in situ were recruited. All patients received IMRT and IGRT using kilovoltage cone-beam computed tomography (kVCBCT). kVCBCT datasets were registered to the planning dataset, recontoured and the original plan recalculated on ...

Purpose: To perform a comparative study assessing potential benefits of endorectal balloons (ERB) in post‐prostatectomy patients Methods: Ten retrospective post‐prostatectomy patients without ERB and ten prospective patients with the ERB in situ were treated with IMRT using kilo voltage cone beam computed tomography (kVCBCT) image guidance (IGRT). A kVCBCT dataset from each treatment week was registered to the planning dataset, recontoured and the original plan recalculated on the kvCBCTs to rec...
