Synopsis

Keywords: Phantoms, RadiotherapyWith the increasing use of magnetic resonance imaging (MRI) in radiotherapy (RT), guidelines for the use of MRI in RT have recently been published, including recommendations for quality assurance (QA) tests. This project investigates whether anthropomorphic phantoms can be more beneficial to comply with these guidelines compared to other phantoms. The performance of the anthropomorphic phantom has been compared to other phantoms. The anthropomorphic phantom has been shown to be useful in QA for MRI-CT registration and end-to-end test that cannot be performed by other phantoms.
