Abstract

We describe a portable readout system for an X-Ray hybrid detector based on the Medipix2 pixel readout chip. The Medipix2 chip (256 x 256 square pixels with 55 mu m pitch) is bump-bonded with a pixellated Silicon sensor 300-micron thick. The readout system consists of a simple small size electronic card based on a single powerful microcontroller and can be connected to a PC through the widespread Universal Serial Bus (USB) interface. The reduced size of the final card (3.8 cm x 4.8 cm) makes it suitable for special applications like dental radiology.
