The current image-guided radiotherapy systems are suboptimal in the esophagus, pancreas,
kidney, rectum, lymph node, etc. These locations in the body are not easily accessible for …

The use of modern MRI technology in radiotherapy is fast growing. MRI is entering all facets
of radiotherapy. This review will start with a very short overview of the newest developments …

Radiation therapy (RT) is an essential component of effective cancer care and is used
across nearly all cancer types. The delivery of RT is becoming more precise through rapid …

At the UMC Utrecht, The Netherlands, we have constructed a prototype MRI accelerator.
The prototype is a modified 6 MV Elekta (Crawley, UK) accelerator next to a modified 1.5 T …

The integration of 1.5 T MRI functionality with a radiotherapy linear accelerator (linac) has
been pursued since 1999 by the UMC Utrecht in close collaboration with Elekta and Philips. …

PURPOSE/OBJECTIVES: In radiotherapy the healthy tissue involvement still poses serious
dose limitations. This results in sub-optimal tumour dose and complications. Daily image …

Background and purpose The promise of the MR-linac is that one can visualize all anatomical
changes during the course of radiotherapy and hence adapt the treatment plan in order to …

Integrating magnetic resonance imaging (MRI) functionality with a radiotherapy accelerator
can facilitate on-line, soft-tissue based, position verification. A technical feasibility study, in …

In the framework of the development of the integration of a MRI-scanner with a linear accelerator,
the influence of a lateral, magnetic field on the dose distribution has to be determined. …
