Description
In addition to intra-operative probes, compact gamma cameras are very attractive to
provide more efficient radio-labeled tumors localization. In this context, our
group has developed a high resolution intra-operative imager, POCI (Per-Operative
Compact Imager) dedicated to nuclear medicine purposes. The current POCI prototype
is based on a 40 mm diameter intensified position sensitive diode coupled to a
gamma head module. The imaging performances at 140 keV gamma energy are a spatial
resolution of 2.3 mm FWHM and a corresponding detection efficiency of 10.7 cps/µCi.
This camera is now the subject of a hospital program for a clinical research
(clinical protocol N° P040417) including 200 patients in collaboration with the
Tenon hospital (Paris). POCI is currently evaluated in sentinel node detection
protocol for breast cancers staging. Preliminary results, obtained both in nuclear
medicine department and theater block, already demonstrate that the imaging
performances of POCI suit intra-operative imaging conditions as far as compactness,
exposure time and spatial resolution are concerned. Overall imaging performances
and first clinical evaluations will be extensively presented and discussed.
