High-sensitivity CCD image sensor enhances patient safety in digital radiography
To reduce x-ray dosage and enhance patient safety in digital radiography, ON Semiconductor has released the KAF-09001 CCD image sensor. It enables video imaging under reduced x-ray dosage conditions with the same critical imaging performance as the company’s, earlier KAF-09000, which is used for digital radiography image capture. However, it incorporates an improved output architecture that supports a high sensitivity video mode, claimed to facilitate patient positioning while minimising overall x-ray exposure.
Resolution is 9Mpixels, and the same high sensitivity, low-noise 12micron pixels as the KAF-09000. The KAF-09001 however, has a quad-output design which supports readout speeds up to 20MHz, providing a 10 fold increase in full resolution frame rate and up to 10frame/s video preview when the device is operated with 3 x 3 binning.
The KAF-09001 is available today in both standard and engineering grades in a RoHS-compliant CERDIP-60 package, with an integrated CuW cooling plate. It is available with monochrome spectral sensitivity in both sealed and taped glass configurations.
