Abstract The increased utilisation of magnetic resonance imaging ( MRI ) in radiation therapy RT has led to the implementation simulators for treatment planning and influenced development ‐guided systems. There is extensive literature on advantages tumour volume organ‐at‐risk delineation compared computed tomography. provides both anatomical functional information RTP as well quantitative assess response adaptive treatment. Despite many , introducing an simulator into a department challenge....

Toxicity to cardiac and coronary structures is an important late morbidity for patients undergoing left-sided breast radiotherapy. Many current studies have relied on estimates of doses assuming standardised anatomy, with a calculated increase in relative risk 7.4% per Gy (mean heart dose). To provide individualised dose, delineation various patient images required. Automatic multi-atlas based segmentation can consistent, robust solution, however there are challenges this method. We aiming...

Introduction To compare the differences in setup errors measured with electronic portal image (EPI) and cone-beam computed tomography (CBCT) patients undergoing tangential breast radiotherapy (RT). Relationship between errors, body mass index (BMI) size was assessed. Methods Twenty-five postoperative RT to were consented for this study. Weekly CBCT scans acquired retrospectively registered planning CT three dimensions, first using bony anatomy registration (CBCT-B) again tissue outline soft...

This study aimed to evaluate the current use of imaging technologies for planning and delivery radiotherapy (RT) in Australia.An online survey was emailed all Australian RT centres August 2015. The inquired about practices during treatment processes. Participants were asked types image-guided (IGRT) disease sites they used for, reasons implementation, frequency future plans IGRT their department.The completed by 71% centres. All respondents had access computed tomography (CT) simulators...

The purpose of this study was to determine the impact magnetic resonance imaging (MRI) geometric distortions when using MRI for target delineation and planning whole‐breast, intensity‐modulated radiotherapy (IMRT). Residual system combined systematic patient‐induced are considered. This retrospective investigated 18 patients who underwent whole‐breast external beam radiotherapy, where both CT MRIs were acquired treatment planning. Distortion phantoms imaged on two systems, dedicated (a wide,...

Abstract Background Diffusion‐weighted imaging (DWI), a quantitative magnetic resonance (qMRI) technique, has the potential to aid in disease characterization and treatment response monitoring. MR‐Linacs (MRLs) enable simultaneous DWI acquisitions during radiotherapy, uniquely aiding collection of large‐scale datasets for biomarkers, such as DWI‐derived apparent diffusion coefficient (ADC), without additional patient burden. However, limited data reporting on variability MRL scanner...

Background Subclinical left ventricular dysfunction detected by 2-dimensional global longitudinal strain post breast radiotherapy has been described in patients with cancer. We hypothesized that postradiotherapy may be site specific, based on differential segmental dose received. Methods and Results Transthoracic echocardiograms were performed at baseline, 6 weeks, 12 months 61 chemotherapy-naïve women left-sided cancer undergoing tangential radiotherapy. Radiation received within basal,...

Abstract Introduction Detailed, published surveys specific to Australian breast radiotherapy practice were last conducted in 2002. More recent international include a E uropean survey 2008/2009 and S panish 2009. Radiotherapy techniques continue evolve, the utilisation of new techniques, such as intensity‐modulated radiation therapy ( IMRT ), is increasing. This aimed determine current practices across A ustralia. Method An online was completed by 50 69 ustralian treatment centres. Results...

The magnetic resonance linear accelerator (MR-Linac) offers a new treatment paradigm, providing improved visualisation of targets and organs at risk while allowing for daily adaptation plans in real time. Online MR-guided adaptive has reduced uncertainties; however, the additional time resource requirements may be concern. We present our experience integrating an MR-Linac into busy department provide recommendations clinical efficiency. Furthermore, we discuss potential future technological...
