drawn by the radiographers were reviewed offline by a clinical oncologist and 94.2% of fractions were deemed acceptable. In our centre, following a comprehensive training programme and with patient specific instructions available at time of treatment, 117 images from six patients treated on a MR Linac were contoured online by either radiographer or clinician and the same images contoured offline by the alternate profession. Volumetric and dosimtric parameters were compared. There was no significant difference in volume size between the two groups and 57 plans created using the radiographer online contours and overlaid with clinicians’ offline contours were all deemed acceptable. Work has commenced with bladder cancer and oligometastases patients. Radiographer contouring has also demonstrated an advantage of increasing machine capacity and offering more flexible appointment times to patients.

Abstract

The concept of advanced practice is well-established in the United Kingdom, Australia and Canada. It has been slowly gaining traction in Singapore with our first advanced practice radiation therapist (APRT) appointed in 2011. In the past decade, Breast radiotherapy has seen remarkable improvement in areas such as immobilization, treatment techniques, fractionation and motion management. The availability of technology has also driven image verification and therefore accuracy in treatment, impacting treatment outcomes. The APRT role is to lead and support change with careful considerations, collect data to ensure right directions, educate to ensure growth and understanding as well as engage in continuous research to ensure evidence-based practice. The establishment of APRT in NCCS has enhanced workflow efficiency, improved professional knowledge of the radiation therapists, created a clinical career progression pathway, promoted inter-professional communication and collaboration in clinical care and enhanced service quality with a patient-centered care delivery.

Department of Radiation Physics, Chongqing University Cancer Hospital, Chongqing, China

Abstract

Image-guided adaptive radiation therapy (IGART) has revolutionized the field of oncology by enabling the precise delivery of radiation to tumor targets while minimizing damage to surrounding healthy tissues. This presentation will outline the key concepts and advancements in IGART, focusing on Surface Guided Radiation Therapy (SGRT), the combination of SGRT with Cone Beam Computed Tomography (CBCT), and emerging technologies such as Magnetic Resonance (MR) guidance.
