Flat panel sensor C9732DK-11 For soft X-ray imaging, cassette type with USB 2.0 interface Large photodiode area: 120 × 120 mm The C9732DK-11 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 USB 2.0 interface can realize fast data transfer with the C9732DK-11. Features Applications 2400 × 2400 pixels (50 µm pitch) X-ray imaging (optimized to 17 keV) High resolution 14-bit digital output (USB 2.0 interface) High-speed imaging: 1 frame/s No dead area (insensitive area) due to seamless structure Compatible with HAMAMATSU API (DCAM-API) Structure The C9732DK-11 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 twodimensional photodiode array, row-scanning vertical shift register, and 8 charge amplifier arrays. Each charge amplifier array has a horizontal shift register and consists of 300 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.
