Hybrid pixel detectors represent a new generation of digital X-ray camera working in a photon counting mode that can replace conventional charge integration in 2D detectors. This novel approach involves several advantages [1], such as the absence of dark noise, a high dynamic range and photon energy discrimination. This suggests that hybrid pixels could represent optimal digital X-ray detectors of low energy X-ray beams as used in small animal computed tomography (CT). We investigate the capability to perform cone-beam CT using either the hybrid pixel camera XPAD3 [2] or the CCD camera DALSA XR-4 within the micro-CT irradiation setup PIXSCAN developed at CPPM
