Samsung unveils flat-panel X-ray detector Imaging
sensor converts invisible X-ray images into
digital signals 23 Nov 2007 The flat-panel X-ray
measures 45cm x 46cm and boasts a 3,072 x 3,072
(9.4-megapixel) resolution providing ultra-high
definition images. To create its flat-panel
X-ray, Samsung attached photodiodes to a TFT
substrate produced using its proprietary
amorphous silicon technology. The device will be
available worldwide from the first quarter of
2008.
