BACKGROUND To assess the impact of incremental modifications of treatment planning and delivery technique, as well as patient anatomical factors, on late gastrointestinal toxicity using data from the TROG 03.04 RADAR prostate radiotherapy trial. METHODS The RADAR trial accrued 813 external beam radiotherapy participants during 2003-2008 from 23 centres.(More)
BACKGROUND Registering CTs for patients receiving external beam radiotherapy (EBRT) with a boost dose from high-dose-rate brachytherapy (HDR) can be challenging due to considerable image discrepancies (e.g. rectal fillings, HDR needles, HDR artefacts and HDR rectal packing materials). This study is the first to comparatively evaluate image processing and(More)
The radiographer I am today is not the same radiographer I was in 1982 – my role has changed. This change did not occur by chance; it may have started out as an organic process but ended up as something that was directed and intentional. This paper reflects on my experiences in driving and advocating cultural change in radiography in my hospital and beyond.(More)
This study investigates the associations between spatial distribution of dose to the rectal surface and observed gastrointestinal toxicities after deformably registering each phase of a combined external beam radiotherapy (EBRT)/high-dose-rate brachytherapy (HDRBT) prostate cancer treatment. The study contains data for 118 patients where the HDRBT CT was(More)
As part of a study of the radiation oncology workforce, radiation oncology medical physicists (ROMPs) who had worked in Australia were surveyed regarding their attitudes to participating in research. Responses from 88 ROMPs were available for analysis, representing a broad mix of employment situations and research experience. Greater than 70% of ROMPs(More)
INTRODUCTION To investigate the accuracy of deriving dose-volume histogram (DVH) parameters from deformably registered data by comparing values with the simple addition of DVHs from each phase of a combined external beam radiotherapy (EBRT)/high-dose-rate (HDR-BT) brachytherapy prostate treatment. METHODS Eighty-two patients received EBRT in 23 fractions(More)
INTRODUCTION The objectives of this research were to: (1) determine the extent of Australian radiation therapists (RTs) research participation; (2) evaluate the impact of research involvement on career perceptions (3) explore which research topics require investigation and (4) identify benefits and barriers to research participation. METHODS This study(More)
BACKGROUND Derivation of dose-volume correlated with toxicity for multi-modal treatments can be difficult due to the perceived need for voxel-by-voxel dose accumulation. With data available for a single-institution cohort with long follow-up, an investigation was undertaken into rectal dose-volume effects for gastrointestinal toxicities after(More)
