Abstract
This paper presented a design of an x-raydetector using CMOS image sensor. The main components consist of CMOS sensor, taper fiber optic, and image intensifier screen. CMOS sensor offers various advantages including miniature-sized, low power consumption and cost effective. CMOS-based digital camera becomes hence very demanding due to its potential application in multimedia and information technology. To apply the CMOS sensor as x-ray detector, xray- to-visible light convector is required. Our key component of x-ray-to-visible light converter is an image intensifier screen mounted on the wider end of taper fiber optic. The narrow end of the taper fiber optic is coupled on the half-inch CMOS image sensor. In order to get higher image quality and system flexibility, more versatile CMOS image-sensor controller are preferable. Such complicate designs are made possible by the creation of entirely VHDL reconfiguration and programmable components- the so-called Field programmable Gate Array (FPGA). The designed x-ray-detector with CMOS sensor camera has been tested to capture a bony structure. The result is very promising.
