Abstract :
A new technique for medical imaging, “3γ imaging”, is studied by our group at SUBATECH for few years. A small liquid xenon time projection chamber prototype has been built in order to demonstrate the feasibility of this technique. With an ultra-low-noise front-end electronics, the energy deposit and resolution of 511 keV γ-ray as a function of drift electric field (E) is measured with high precision. 500 μm of z resolution is estimated by measuring the charge carriers drift velocity and time resolution.
