In modern radiotherapy, verification of the treatment to ensure the target receives the
prescribed dose and normal tissues are optimally spared has become essential. Several …

Prostate motion during external-beam radiotherapy can affect outcomes in patients with
localized prostate cancer. Prostate motion and deformation are currently being …

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 …

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 an ideal radiotherapy procedure, the treatment system would continuously adapt the
radiation beam delivery to changes in the tumor position. The development of such a …

Purpose: The aim of this work was to assess the accuracy of kilovoltage (kV) cone-beam
computed tomography (CBCT)–based setup corrections as compared with orthogonal …

PURPOSE: To evaluate the use of the ultrasound-based BAT system for daily prostate
alignment. MATERIALS AND METHODS: Prostate alignments using the BAT system were …
