The C7930-01 MOS Flat Panel Sensor was
designed for acquiring dynamic X-ray images.
The C7930-01 consists of array board and control
board. The array board is composed of a CsI
scintillator directly deposited onto two
dimensional active detector matrix made up of
photodiode array sensitive to the emitting light of
scintillator with FET switch and integrated
amplifier circuit. The charge sensitive amplifiers
of 4416 channels with horizontal shift resister
sense the charge on each of the video line and
transfer video signal via A/D converter. The 2x2
binning mode of the C7930-01 allows you faster frame rate of 7 frames / second. The video image data will be
transferred to the display through a digital image grabber board , to get a dynamic, high quality X-ray images.
