Three-dimensional polymer gel dosimetry using an onboard 0.35 T magnetic resonance imaging scanner: A simulation study

At present, T2-measurement sequence is not open to the authors on a ViewRay system. [...]in this communication, numerical simulations have been performed to investigate the feasibility of using polymer gel dosimetry at 0.35 T. The goal is to answer one question: [...]the limitation of gamma passing rate as a measure of treatment quality in patient geometry has been discussed in a number of papers.
