DEFGEL Verification of Realtime IGRT Delivery Platform

Polymer gel dosimetry shows the potential for the measurement of 3D dose distributions through the use of deformable phantoms. We are currently using the normoxic polyacrylamide gel DEFGEL to verify a real time IGRT platform currently under development. After the characterization of the DEFGEL paired with an MRI readout system, the gel will be incorporated into a deformable motion phantom for the verification of the IGRT platform.
