imXgam
The X and Gamma Imaging team (imXgam) conducts interdisciplinary research activities for ionizing radiation imaging applications in the field of health and energy. These are based on the expertise in electronics and instrumentation of IN2P3, capitalizing its development for large instruments dedicated to high energy physics.
In this context, the imXgam team has built several generations of hybrid pixel cameras for various applications in crystallography and biomedical imaging. We contribute to the development of data acquisition electronics for positron detection by pixelated probes and for rapid gamma imaging in hadrontherapy and we are involved in the development of a Compton camera for nuclear dismantling and hadrontherapy operations.
The imXgam team is a member of the Crystal Clear collaboration and the OpenGATE collaboration, which develop and maintain the GATE simulation platform. At the national level, the research themes of the imXgam team fit into the context of the activities of the Modeling and Instrumentation GDR for Biomedical Imaging (MI2B).
