Radiotherapy planning using MRI.
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 are geometrically accurate, that effects of p...
متن کاملMR-only simulation for radiotherapy planning White paper: Philips MRCAT for prostate dose calculations using only MRI data
Highly targeted treatment planning is at the foundation of successful radiotherapy. With its superb and tunable soft-tissue contrast, MRI has in recent years emerged as an imaging modality to drive delineation accuracy of targets and organs at risk. With the introduction of the fi rst commercially available MR-only simulation package, Philips continues to pave the way for the adoption and imple...
متن کاملInvestigation on the performance of dedicated radiotherapy positioning devices for MR scanning for prostate planning
The purpose of this study was to investigate performance of the couch and coil mounts designed for MR-simulation prostate scanning using data from ten volunteers. Volunteers were scanned using the standard MR scanning protocol with the MR coil directly strapped on the external body and the volunteer lying on the original scanner table. They also were scanned using a MR-simulation table top and ...
متن کاملComparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction
Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملImaging tumour motion for radiotherapy planning using MRI
Novel technology has made dynamic magnetic resonance imaging (MRI) of lung motion and lung tumour mobility during continuous respiration feasible. This might be beneficial for planning of radiotherapy of lung tumours, especially when using high precision techniques. This paper describes the recent developments to analyze and visualize pulmonary nodules during continuous respiration using MRI. B...
