IMAGE SENSOR Flat panel sensor C9732DK Large area/soft X-ray imaging, high resolution Flat panel sensor C9732DK 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 with C9732DK. Features Applications l High resolution l X-ray imaging (optimized to 17 keV) l 2400 × 2400 pixels (50 µm pitch) l 14-bit digital output l High-speed imaging: 1 frame/s (single operation) l CsI scintillator directly deposited on photosensitive surface l No dead area (insensitive area) due to seamless structure ■ Block diagram PIXEL NUMBER 1 2 2399 2400 2401 4799 4800 PHOTODIODE ARRAY WITH DIRECTLY DEPOSITED CsI SCINTILLATOR VERTICAL SHIFT REGISTER C9732DK 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 300 channel amplifiers with a horizontal shift register. Analog video signals are amplified as the charge on each video line by 2400 ch charge amplifiers with CDS (Correlated Double Sampling) circuits, and are output is obtained from each of 8 amplifier arrays. The control board converts the analog video signal into a 14-bit digital signal and outputs it to an PC through the USB2.0 interface. 5759999 5760000 AMP ARRAY No. 1 EXTERNAL POWER SUPPLY A.vdd, D.vdd (not attached) TIMING PULSE GENERATOR AMP ARRAY No. 8 OSCILLATOR TrgIn TrgOut BIAS GENERATOR BUFFER AMP PROCESSING AMP A/D FIFO USB IC BUFFER AMP PROCESSING AMP A/D Note: Signals are read out in order of pixel number.

(Avoid using a switching power supply.) A optional power source (PS4ML) is provided for AC100, 115, 230 V input voltages. A power cable (terminated with a JSTJ-C9-2C plug at one end and open at the other end; 2 m; see Table 1.) and an external trigger cable (terminated with an FGG.OB.304.CLAD56 plug at one end and open at the other end; 5 m; see table 2.) comes supplied with C9732DK. C9732DK does not include USB cable. The voltages described above are specified at the flat panel sensor side. The impedance of the power cable attached with the flat panel sensor is low enough but it causes 0.1 V approx. drop. Therefore the voltage at the power source side should be set 0.1 V higher than the voltage specified above. Install a noise filter on the AC power input line to prevent surges on the AC line. DCAM-API (Digital Camera Application Programming Interface) produced by Hamamatsu supports C9732DK. The driver software, DLL and sample software are included in DCAM-API. The latest version of DCAM-API can be downloaded from http:/ /www.dcamapi.com/. The USB receptacle is mini-B type. The mini-B USB cable is not attached. The earth terminal must be connected to a stable earth point to eliminate noise from surroundings.
