NASA/LaRC has a requirement for Amorphous Silicon X-Ray Detector that meets the following specifications:
-Active Pixel Area at Least 29.1 x 40.5 cm (11.5 in. x 16.0 in)
-In the central (6" X 9") input area there will be no uncorrectable clusters. In the peripheral input area there will be a maximum of six (6) uncorrectable clusters. None of the uncorrectable clusters will exceed a size of 3 x 3 pixels, or better
-At Least 2,304 (h) by 3,200 (v) Active Pixels
-Pixel Pitch no greater than 127 ยต
-Limiting Resolution at least 3.94 lp/mm
-DQE greater then 30%
-MTF, X-Ray greater than 45% at 1 lp/mm
-Energy Range at least 40 - 150 kVp
-Fill Factor at least 57%
-Contrast Ratio over 12cm less than 2%
-Contrast Ratio over 1cm less than 10%
-At least 14 bit A/D Conversion
-Maximum Frame Rate greater than or equal to 1 fps for full imager
-Data Output shall be Gigabit Ethernet
-cables to be 50 feet in length
The X-Ray detector is replacing an existing Hytec X-Ray Detector and must be compatible with the existing Hytec FlashCT system installed as NASA Langley Research Center (LaRC). For the new X-Ray Detector to be compatible, a software upgrade to the existing FlashCT(TM)-DAQ software will be required. This acquisition also includes warranty and maintenance and technical support on both the software and hardware for 1 year.
