Abstract
Ironizing radiation acoustic imaging (iRAI) is a novel imaging concept with the potential to map the radiation dose delivery in real time during external beam radiation therapy. In this study, iRAI volumetric dose mapping was achieved with 2D matrix transducer array using a C-shape 3D conformal treatment plan with clinically relevant setting and a moving beam plan in both phantoms and rabbit model in vivo. With the unique ability to map the volumetric dose delivery in real time, iRAI 3D dose mapping can be developed into a new tool for quantifying the accuracy of dose delivery of radiation therapy.
