The Medipix2 ASIC, the successor of the Medipix1 chip, is a high spatial, high contrast resolving CMOS pixel read-out chip working in single photon counting mode. It benefits from the quick progress of CMOS technology which allows enhanced functionality of the pixel cell at the same time as providing a significant reduction in pixel size. The chip can be combined with different semiconductor sensors which convert the X-rays directly into detectable electric signals. This represents a new solution for various X-ray and gamma-ray imaging applications.
