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 کاملMRI-only treatment planning: benefits and challenges.
Over the past decade, the application of magnetic resonance imaging (MRI) has increased, and there is growing evidence to suggest that improvements in the accuracy of target delineation in MRI-guided radiation therapy may improve clinical outcomes in a variety of cancer types. However, some considerations should be recognized including patient motion during image acquisition and geometric accur...
متن کاملverification of treatment planning system using imsure qa software in non-reference condition
objectives: the aim of this study was to verify the treatment planning systems (tpss). the next aim was to validate imsure qa software for patient-specific qa in radiotherapy clinics. material and methods: we used imsure qa software (standard imaging, v 3.5) for verification of 92 non-imrt plans (540 fields) in 10 radiotherapy clinics. to validate the imsure, dose measurement was performed in ...
متن کاملVerification of Monitor unit calculations for eclipse Treatment Planning System by in- house developed spreadsheet
Introduction: Computerized treatment planning is a rapidly evolving modality that depends on hardware and software efficiency. Despite ICRU recommendations suggesting 5% deviation in dose delivery the overall uncertainty shall be less than 3.5% as suggested by B.J. Minjnheer. J. In house spreadsheets are developed by the medical physicists to cross-verify the dose calculated by the Treatment Pl...
