In a preceding work a new compact gamma camera based on the Hamamatsu H8500 PSPMT and on a custom developed electronics was presented [1]. The core element of such electronics is a microcontroller that operates the transfer of the sampled data to a PC using a USB link in full speed modality; This transfer utilizes on one side a firmware that controls the operation performed by the microcontroller and on the other side a software that trough a graphical interface make the analysis of the acquired data possible. Both were optimized considering the nature of the data coming from the gamma camera and on the other the limitation imposed by the USB protocol. Although they were conceived for a particular gamma camera the requirements and optimizations realized still have a general interest for any position sensitive based gamma camera.
