Abstract: The electronCT technique is a novel imaging method based on the multiple Coulomb scattering of electrons of energies in the range of 100 to 250 MeV. One potential use case lies in the context of radiation therapy with “very-high energy electrons” or VHEE. This technique involves using a pencil beam of electrons and a single detection layer to determine the beam profile. Electron scattering within a sample results in a change in the beam profile. This change in profile is used to scan through the sample to reconstruct the 2D or 3D tomographic image of the sample. Given that electrons of similar energies are also used for VHEE-based radiotherapy, electronCT offers the potential to be used as an in-situ imaging method just before treatment. Measurements have been performed at the ARES linear particle accelerator at an electron energy of 155 MeV using multiple mouse phantoms as samples and a Timepix3 silicon pixel detector as the sensor to demonstrate the feasibility of the technique. Further simulation studies are currently being conducted using allpix squared simulation tool based on Geant4 to further validate this method and its effectiveness. Results from all these studies will be presented in this contribution.
