C9730DK-10
Large area soft X-ray imaging, high resolution
Flat panel sensor C9730DK-10 is two-dimensional CMOS image sensor module designed for X-ray imaging which requires high resolution,
large area and wide dynamic range. A target material of X-ray source and X-ray energy adequate for the sensor is Mo and 17 keV. The
device shape is thin cassette which incorporate on-chip high-resolution scintillator and a control board. An on-board USB2.0 interface can
realize fast data transfer to C9730DK-10.
Features
Applications
l High resolution
l 1056 × 1056 pixels (50 µm pitch)
l 14-bit digital output
l High-speed imaging:
4 frame/s (single operation)
l CsI scintillator directly deposited on photosensitive surface
l No dead area (insensitive area) due to seamless structure
l X-ray imaging (optimized to 17 keV)
s Block diagram
C9730DK-10 is a lightweight and compact flat panel sensor consisting of a sensor board and a control board. The sensor board
also has 8 charge-sensitive amplifier arrays each having 132 channel amplifiers with a horizontal shift register. Analog video
signals are amplified as the charge on each video line by 1056 ch charge amplifiers with CDS (Correlated Double Sampling)
circuits added, and are output each of 8 amplifier arrays. The control board converts the analog video signal into a 14-bit digital
signal and outputs it to an external frame grabber through the USB2.0 interface.
