Abstract :
Originally developed for HEP applications, the ISPA (Imaging Silicon Pixel Array) tube, a position sensitive photon detector based on the hybrid technology, can also be envisaged for biomedical applications. By coupling it to scintillating crystals or crystal arrays (YAP) we built a γ-camera and detected through a collimator the 122 keV γ-rays from a57Co source. Depending on the nature of the ISPA tube input window (glass fibre window or quartz window) and of the scintillator (planar YAP or YAP array) spatial resolutions equal or better than 100 μm (FWHM) and energy resolutions of 20% have been obtained.
