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 511keV γ-ray as a function of drift electric field (E) is measured with high precision...
3γ imaging is a new nuclear medical imaging technique which has been suggested by Subatech laboratory, this technique involves locating three-dimensional position of the decay of an innovative radioisotope (β+, γ) emitter, the 44Sc. In order to demonstrate experimentally the feasibility of 3γ imaging, a first prototype, XEMIS1 (XEnon Medical Imaging System) was developed. The last published results...
We report on the electronic dedicated to the acquisition of the ionization current signal induced by the interactions of γ-rays inside a Compton telescope with Liquid Xenon. In order to achieve sub-millimeter resolution we successfully adapted an existing ASIC originally designed for semi-conductor detector with low input capacitance and low dark current called IDeF-X-LXe, and fabricated in a standard...
We report on the development of a liquid-xenon time-projection chamber, designed to validate a new medical imaging concept named ??3?? imaging??. The advantages of detection gamma-induced scintillation light with a gaseous photomultiplier (GPM) operating in cryogenic mode are discussed; first results are presented.
