flat panel sensor c9730dk-10 for soft x-ray imaging, cassette type with usb 2.0 interface photodiode area: 52.8 52.8 mm www.hamamatsu.com 1 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. high resolution 1056 1056 pixels (50 m pitch) 14-bit digital output (usb 2.0 interface) high-speed imaging: 4 frames/s no dead area (insensitive area) due to seamless structure 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 ar ray 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 convert ed to fluorescence, which then enters the two-dimensional photodiode array where electric charge is accumulated in each pixel according to the ligh t intensity. the accumulated charge on each row is sequentially selected by the row -scanning vertical shift register, transferred to the amplifi ers 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 int erface. kaccc0268ec vertical shift register timing pulse generator oscillator pixel number trgout a/d external power supply a.vdd, d.vdd (not attached) photodiode array with directly deposited csi scintillator buffer amp buffer amp processing amp processing amp 12 1115136 1115135 1056 1055 2112 2111 1057 bias generator usb ic trgin fifo a/d fifo video data flat panel control (usb 2.0 interface) charge amp array no. 1 (with horizontal shift register, 132 ch) charge amp array no. 8 (with horizontal shift register, 132 ch) sensor board control board note: signals are read out in order of pixel number. kaccc0268ec compatible with hamamatsu api (dcam-api) x-ray imaging (optimized to 17 kev) features applications
