flat panel sensor C7921 is a digital x-ray image sensor newly developed as key devices for non-destructive inspection, biomedic al imaging, x- ray microscopy and other real-time x-ray imaging applications requiring high resolution and high image quality. C7921 consists of a sensor board and a control board, both assembled in a thin, flat and compact package. the sensor board contains a csi scintillator plate, a two-dimensional photodiode array with fet switches and a signal processing ic chip. the photodiode array has a 1056 1056 pixel format with mi nimized blooming and is highly sensitive to bluish green light emitted from the csi scintillator. each row of pixels is addressed in se quence by the vertical shift register connected to the gate line. light emission occurs when x-rays are absorbed in the csi scintillator. this light emission enters directly into the two-dimens ional photodiode array where an electric charge is stored in each pixel according to the light intensity. this charge is then transferred to the corresponding data line by applying a control signal to the vertical shift register. the sensor board also has 8 charge sensitive amplifier arrays each having 132 channel amplifiers with a horizontal shift regist er. these amplifiers with a total of 1056 channels are connected to a cds (correlated double sampling) circuit that senses the charge on each video line and sends it as the analog video signal from each amplifier array. the control board converts the analog video signal into a 12-bit digital signal and outputs it to an external frame grabber from a 12-bit parallel port. C7921 delivers a frame rate of 16 frames per second using 4 4 binning and is ideal for high frame rate applications, also ide al for applications requiring high resolution because of its 50 m pixel size. massive digital image data can easily be monitored on a display unit by using a frame grabber board and video memory installed in the pc. C7921 will prove ideal tools for real-time x-ray imaging and processing whe re easy-to-use, high-resolution x-ray digital image sensors are needed. features l non-destructive inspection l digital x-ray photography applications l high quality image: 1056 1056 pixels l pixel size: 50 50 m l no image distortion l digital output (12 bits) l high-speed imaging by binning operation: 16 frames/s (4 4 binning) l wide dynamic range l high cost performance image sensor flat panel sensor high resolution and high frame rate C7921 amp array no. 1 shift register timing pulse generator oscillator exttrg pixel number vsync hsync pclk a/d intext intext binning (bin0, bin1) external power supply a. vdd, d. vdd v (7.5) (not attached) amp array no. 8 photodiode array buffer amp buffer amp processing amp processing amp 12 1115136 1115135 1056 1055 2112 2111 1057 scintillator (52.8 mm 52.8 mm) bias generater fifo a/d fifo video output (12 bit digital) block diagram kaccc0170ea 1
