Flat panel sensor
C9730DK-10
For soft X-ray imaging, cassette type with USB 2.0 interface
Photodiode area: 52.8 × 52.8 mm
The 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 incorporates on-chip high-resolution scintillator and a control board. An on-board
USB 2.0 interface can realize fast data transfer to the C9730DK-10.
Features
High resolution
1056 × 1056 pixels (50 μm pitch)
14-bit digital output (USB 2.0 interface)
High-speed imaging: 4 frames/s
No dead area (insensitive area) due to seamless structure
Compatible with Hamamatsu API (DCAM-API)
Applications
X-ray imaging (optimized to 17 keV)
Structure
The C9730DK-10 is comprised of a sensor board and a control board. Mounted on the sensor board is a CMOS image sensor chip made up of a
two-dimensional photodiode array, row-scanning vertical shift register, and 8 charge amplifier arrays. Each charge amplifier array has a horizontal
shift register and consists of 132 ch charge amplifiers with CDS circuit.
CsI scintillator is directly deposited on the two-dimensional photodiode array. X-rays incident on the scintillator are converted to fluorescence,
which then enters the two-dimensional photodiode array where electric charge is accumulated in each pixel according to the light intensity. The
accumulated charge on each row is sequentially selected by the row-scanning vertical shift register, transferred to the amplifiers through the data
line, and converted to a voltage signal. Then an analog signal is sent out from each amplifier array by scanning the horizontal shift register.
The control board converts the analog signal into a 14-bit digital signal, which is then output to a PC through the USB 2.0 interface.
