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 …

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 …

Background The treatment results of external beam radiotherapy for intermediate and high
risk prostate cancer patients are insufficient with five-year biochemical relapse rates of …

Background Magnetic resonance-guided high intensity focused ultrasound (MR-HIFU) has
recently emerged as an effective treatment option for painful bone metastases. We describe …

We evaluated the acute and late toxicity after high-dose intensity-modulated radiotherapy (IMRT)
with fiducial marker-based position verification for prostate cancer. Between 2001 and …

Background Accurate tumor bed delineation after breast-conserving surgery is important.
However, consistency among observers on standard postoperative radiotherapy planning CT …

The application of thermal modelling for hyperthermia and thermal ablation is severely
hampered by lack of information about perfusion and vasculature. However, recently, with the …

Magnetic resonance imaging (MRI) provides excellent soft-tissue contrast and allows for
specific scanning sequences to optimize differentiation between various tissue types and …

Background Standard radiotherapy is the treatment of first choice in patients with symptomatic
spinal metastases, but is only moderately effective. Stereotactic body radiation therapy is …

Background. To benefit most of focal treatment of prostate tumours, detection with high precision
of all tumour voxels is needed. Although diffusion-weighted imaging (DWI) and dynamic …
