3D-CRT radiotherapy allows prostate tumours to be targeted more selectively. In collaboration with the UK's Institute of Cancer Research, IES developed a training and information site for 3D-CRT. The web site allows registered oncologists to work through a structured course with access to supporting material.

At the core of the site is a simulation of the clinical tool used for outlining target (e.g. the tumour) and protected (e.g. the bladder) areas on CT scan slices. Once outlining is complete, users are given instant feedback on the accuracy of their work based on “gold standard” outlines provided by experts from the Academic Unit of Radiotherapy and Oncology.
