Dual-Energy Cone-beam Computed Tomography (CBCT)

Our investigation in Cone-Beam Computed Tomography takes advantage of the potential of the X-ray tube to cover a large range of fastly switchable energies from 40 kV to 120 kV along with remotely exchangeable filters which enables dual-energy radiograph reconstruction. Dual-energy could be essential in hadron therapy as dual-energy CBCT images offer the theoretical possibility to improve the estimation of the proton and carbon ion range in patients for precise dose deposition to spare organs at risk and healthy tissue maximally. The investigations use hybrid Monte Carlo / deterministic simulations with potential validation in the new Austrian hadron therapy center, MedAustron (Wr. Neustadt), where four ImagingRing units have been installed. The clinical end result will be the reduction of uncertainty in ion range and its associated treatment margin.

Detailed information about the ImagingRing and the cooperation between the radART-Institute and MedAustron can be found here.
