Radiotherapy planning using MRI
Physics in Medicine and Biology, 2015 The use of magnetic resonance imaging (MRI) in radiotherapy (RT) planning is rapidly expanding. We review the wide range of image contrast mechanisms available to MRI and the way they are exploited for RT planning. However a number of challenges are also considered: the requirements that MR images are acquired in the RT treatment position, that they ...

Factors Affecting Implementation of Radiological Protection Aspects of Imaging in Radiotherapy
Applied Sciences, 2023 Dramatic improvements in radiotherapy equipment have allowed radiation fields to be conformed to tumours for more accurate treatment. Successful delivery often requires imaging at every treatment fraction, a method known as image guided radiation therapy
