Design And Implementation Of The Imaging Control System Of The Digital Fluoroscopy Imaging System

This paper introduces the imaging system of the DRF(Digital Radio Photographic Fluoroscopy System) and the architecture as well as the relationship between the various parts, and we designed the heart of the DRF - the imaging control system. The system composed by the generator, the X-Ray tube, the AEC / ABC unit, the image intensifier, the automatic iris control system, CCD camera and the main controller, this article focuses on the Design and Implementation of the automatic iris control system, the Automatic Exposure Control (AEC) / Automatic Brightness Control (ABC) board and the main controller.In this paper, all the hardware and software have been realized and tested, we use the Keil C51 and gcc AVR to compile the source code of different MCUs, and we use Proteus 7.4 to do the hardware timing simulation. Also, we use the powerful Altium Designer to draw the schematic and PCB layout.In the final paper, we tested the whole system, and made some improvement. The Result is that the imaging control system is a complete imaging control system of the DRF, which is combined with advanced computer technology, control theory and X-ray imaging technology.
