The cameras feature low power consumption, high resolution, excellent DQE, and the same flexible readout modes as their predecessors, the Shad-o-BoxTM and Shad-o-SnapTM product lines. The SkiaGraph8 camera is capable of real-time imaging at up to 1.4 fps, 12-bit digital contrast resolution, 5 Ip/mm spatial resolution and features a choice of scintillators providing impressive sensitivity as high as 250 ADU/mR. A GdOS (Gadox) integrated direct-contact scintillator converts x-ray photons into visible light that is sensed by the CMOS photodiodes. Analog signals from the photodiode sensors are subsequently digitized in eight or more parallel A/D channels and then interleaved for maximum transmission across a high-speed parallel digital interface. The SkiaGraph8 is optimized for the standard 10-50 kV energy range. An EV model for use with higher x-ray energies or dose rates will be available in early 2009. Several scintillator options are available. The SkiaGraph8 camera ships with a desktop power supply and ShadoCam software. Specification Minimum Typical

SkiaGraph X-ray Cameras Resolution: SkiaGraph cameras are available with Gd2O2S phosphor screens such as Kodak-Min-R 2190 or DRZ-Std. The intrinsic resolution of the SkiaGraph camera is 96 μm, which corresponds to just over 5 line pairs per mm. The actual Modulation Transfer Function (MTF) depends on the type of scintillator chosen for the sensor module. A thicker phosphor screen will produce more signal (i.e. higher sensitivity), but at the expense of high-frequency contrast. If the sensor module is primarily used in the sparse sampling mode to achieve faster frame rates, then a scintillator...
