Monte Carlo validation of a mu-SPECT imaging system on the lightweight grid CiGri

à paraître dans Future Generation Computer SystemsMonte Carlo Simulations (MCS) are nowadays widely used in the field of nuclear medicine for system and algorithms designs. They are valuable for accurately reproducing experimental data, but at the expense of a long computing time. An efficient solution for shorter elapsed time has recently been proposed: grid computing. The aim of this work is to validate a small animal gamma camera MCS and to confirm the usefulness of grid computing for such a study. Good matches between measured and simulated data were achieved and a crunching factor up to 70 was attained on a lightweight campus grid

TOPASE-MED : comment repenser l'imagerie TEP grâce aux détecteurs semiconducteurs

International audienceCe papier présente les principaux acquis du projet « tomographe à émission de positons à semiconducteur pour limagerie médicale » (TOPASE-MED), dont lobjectif était détudier la faisabilité et le potentiel dun imageur TEP basé sur la technologie de détecteurs à semiconducteur CdTe. Les objectifs étaient, dune part, de dimensionner par simulation un imageur TEP préclinique basé sur cette technologie, dautre part, de développer les briques technologiques nécessaires à la réalisation dun tel imageur et enfin de démontrer expérimentalement le potentiel de cette technologie à laide dune maquette de dimension réduite
