Abstract

A Gamma Camera for medical applications 10 x 10 cm(2) has been built using a triple GEM chamber prototype. The photon converters placed in front of the three GEM foils, has been realized with different technologies. The chamber, High Voltage supplied with a new active divider made in Frascati, is readout through 64 pads, 1 mm(2) wide, organized in a row of 8 cm long, with LHCb ASDQ chip. This Gamma Camera can be used both for X-ray movie and PET-SPECT imaging; this chamber prototype is placed in a scanner system, creating images of 8 x 8 cm(2). Several measurements have been performed using phantom and radioactive sources of Tc-99m (140 keV) and Na-22 (511 keV). Results on spatial resolution and image reconstruction are presented.
