Abstract
Hybrid pixel detectors for medical X-ray imaging applications with Si and G aAs sensors are compared. Both sensor types are bump-bonded onto the MPEC s ingle photon counting pixel read out chip. The image homogeneity and count rate of the two assemblies are compared. For the GaAs assembly the active l ayer thickness and charge collection efficiency have been measured.
