Introduction
Hyperthermia to temperatures of 41-43°C has been shown to be a valuable sensitizer for radiation- and chemo-therapy in cancer treatment. During hyperthermia treatment (HT) the presence of health staff and accompanying persons in the treatment room is desirable for patient comfort. In this study the electromagnetic stray radiation in the treatment room with respect to limits for...
Introduction
Mild hyperthermia (HT) aims to heat tumour tissue to 40-44°C for 1 h and has proved to increase the therapeutic effect of radiotherapy (RT) with, among others, excellent clinical results for local recurrence of breast cancer. Two patients in our department with breast cancer recurrences were good candidates for combined RT-HT, but had surgical clips in the region to treat....
Introduction:
Most phantoms for patient specific Quality Assurance (QA) are not MR compatible and not MR safe. The Delat4+MR phantom was redesigned to be used in combination with Magnetic Resonance Linear Accelerators (MR-Linac). Here we report extended testing of this phantom and our early clinical experience using the phantom for patient QA.
Materials and Methods:
Since April 2019, a...
Introduction
The MRIdian Linac (ViewRay, Ohio, USA) is a MR-guided radiotherapy system which combines a low field MR scanner (0.35T) with a radiotherapy gantry (6MV linac) located in the magnet split bore. The superior high soft tissue contrast of MRI compared to computed tomography is expected to improve tumor delineation as well as patient setup. However, the geometric accuracy that is...
Introduction: To report about the Tomotherapy implementation and integration in RayStation Treatment Planning System (TPS) version 8a. This new mixed system involved the planning with Raystation and then the export of treatment plans to iDMS, a single database provided by Accuray common for both machines.
Materials and Methods: Two Tomotherapy units were commissioned in November and December...
