In this short video, filmed at ASTRO 2021, Justin Turpin introduces the Elekta Unity MR-guided radiotherapy system. Elekta Unity provides real-time imaging whilst the gantry is rotating and the MLCs are moving, enabling treatments to be tailored according to changes in the patient’s tumour and surrounding anatomy. Turpin explains how new sequencing enables users to see like they’ve never been able to see before in radiotherapy.
