>  A project of a new functional medical imaging technique with a  
> liquid xenon detector was initiated at Subatech since 2 years. We  
> propose to develop a new technique for medical imaging based on a  
> new type of radio-nuclide which emits quasi-simultaneously a  
> positron and a gamma-ray. Considering its physical properties, the  
> scandium-44 was identified today as being the best candidate for  
> this imaging technique for several reasons: the energy of its 3rd  
> gamma-ray (1,157 MeV) is particularly adapted to the detection by a  
> liquid xenon detector, its half life of ~4 h is quite short, it is  
> possible to use scandium-44 associated to scandium-47(beta-  
> emitter) in case of radio-immunotherapy applications.
>
> A first prototype of a liquid xenon detector where scintillation  
> and ionization signals are both measured is under construction at  
> Subatech and will produce results by the end of 2007. In a 2nd  
> phase, it is planned to build a Compton telescope of larger  
> dimension in order to demonstrate the capability of this technique  
> for the small animal imaging. This telescope will make possible the  
> measurement of the direction of the 3rd gamma-ray, emitted by the  
> son nucleus of the scandium-44. This information combined with the  
> line of response measured by a crystal  micro-TEP will make  
> possible the direct location in 3 dimensions of the emission point.
>
> First simulations have already shown the interest of this technique  
> within the framework of the small animal imaging. However, it  
> appears necessary to develop the simulation of the whole project  
> using a software especially dedicated for medical purpose such as  
> GATE (Geant4 Application for Tomographic Emission) in order to  
> precisely evaluate the performances of the proposed camera for  
> small animal and human body imaging.

> Candidate Profile :
>
> Candidates should have recently completed a PhD in experimental  
> subatomic physics by the time of the appointment. The candidate  
> will have to implement under GATE, the liquid xenon Compton He will  
> have to interact with members of labs working in the related topics  
> such as detector R&D, medical imaging and development of new radio- 
> pharmaceuticals. Candidates should have expertise in C++  
> programming and Monte Carlo simulation , in particular with GEANT4  
> application.
