Commissioning IMRT phantoms: A streamlined approach
Intensity Modulated Radiation Therapy (IMRT) is a proven technique for providing conformal dose to targets while sparing normal tissue. The St George Cancer Care Centre (STGCCC) plans to implement IMRT in the near future, intending to concentrate on providing prostate treatments. In anticipation of this a dedicated IMRT plan-check phantom was purchased (CIRS Model 002H9K). Initial work has previously been done at the Illawarra Cancer Care Centre (ICCC) on the use of a basic cubic phantom made up of RMI Solid Water slabs for dosimetric verification of IMRT1. Since then a more elegant IMRT phantom (I’mRT Phantom, Scanditronix-Wellhofer GmBH) has been adopted at ICCC2.
