The electronCT technique is an imaging method based on the multiple Coulomb scattering of relativistic electrons and has potential applications in medical industrial imaging. It utilizes a pencil beam very high energy electron (VHEE, 50–250 MeV) range single detection layer for determination profile. constitutes projectional, two-dimensional thus also qualifies tomographic reconstruction samples. Given simplicity technical setup its location behind sample, synergies with VHEE radiotherapy, making use same source both treatment diagnostics being candidate situ patient localization. At time, several challenges arise from measurement when applied living beings. Measurements performed at ARES linear particle accelerator 155 MeV using mouse phantom Timepix3 silicon pixel detector assembly demonstrate feasibility this technique. Both projectional reconstructions are presented limits technology discussed.
