Description

Ion therapy treatment planning requires an accurate estimate of the energy deposition of the ions per path length (stopping power) in the patient. From a conventional planning CT, Hounsfield units are obtained that have to be converted to stopping power values leading to range uncertainties. Ion computed tomography (iCT) allows to directly measure this quantity. In this scope, research activities of our group, with emphasis on GPU-based image reconstruction, the implementation of an ion CT demonstrator at MedAustron as well as upgrade possibilities, will be presented.
