Shad-o-Box HS cameras contain a large-area, high-resolution CMOS detector with a photodiode pixel array featuring five standard size options of approximately 2×2, 2×6, 3×4, 4×6 and 5×5 inches. The cameras are available in different resolution models featuring either a 135µm, 99/100µm or 49.5µm pixel size.
All detectors are capable of real-time, full-resolution imaging at frame rates up to 66 fps.
The detector array consists of a single CMOS die (no tiling) that contains multiple output taps to enable high frame rates. The video signal is digitized to 14 bits, reassembled (deinterlaced) within the camera’s FPGA, and then transferred directly to the host memory via a high-speed Gigabit Ethernet interface.
The CMOS sensor inside the Shad-o-Box HS camera contains a direct-contact Gd2O2S scintillator such as Carestream Min-R® 2190 or Mitsubishi Chemical DRZ (a CsI option is also available – please contact us for details). The scintillator converts x-ray photons into visible light that is sensed by the CMOS photodiodes.
A thin graphite cover protects the sensor from accidental damage as well as ambient light. The Shad-o-Box HS camera also contains lead and steel shielding to protect the camera electronics from the x-ray radiation. The cameras are sensitive to x-ray energies as low as 15 keV, and may be used with generators up to
225 kVp. Please refer to our application notes for additional information.
