Design And Implementation Of Medical Electronic Endoscope System

Medical electronic endoscope system is the fusion and development product of the traditional endoscope technology and microelectronic technology,digital signal processing technology,computer technology and so on,it has important research and application value in medical and industrial fileds.Through the medical electronic endoscope system,doctors can directly observe the shape of the internal organs,it provides a reliable basis and convenient operations for clinical diagnosis and treatment.At present,the high-end medical electronic endoscope products are still at the starting stage in our country.High resolution,wide field of vision,small distortion and long distance transmission are the main direction of development for the future medical electronic endoscope system.In this paper,basing on the analysis of the internal and external medical electronic endoscope system,starting from the practical application,design and implementation a function prototype for the medical electronic endoscope system based on FPGA and DSP.The function prototype reflects good performance such as easy to operate,clear to image,during the test the system performance stability,achieves the desired design requirements.The main contents of this paper are as follows:1.To carry out the requirements analysis and functional design of the medical electronic endoscope system.Taking the FPGA of EP4CE6E22C8 N of the Altera company and the dedicated image processing chip DM368 of the DaVinci DSP platform of the TI company as the core,designing the main Peripheral circuit schematic diagram,including image acquisition,transmission,processing,display,cold light source and any other modules.2.Againsting the medical electronic endoscope system has no automatic focus function,this paper Proposes an automatic focusing device controlled by the electric motor in the front of the medical electronic endoscope system.3.To programming the EP4CE6E22C8 N chip based on Quartus ? integrated development environment,implement the driver development of data format transformation,and realized the simulation test based on the driver.4.To set up the software development and debugging environment for the image processing based on the DM368,including reseting the function of Linux system,tailoring and compilation the Kernel,analyzing and introducing the application programs of the image processing.5.To set up the test platform of the medical electronic endoscope system,testing and analyzing the relevant performance of the system,such as system delay,color reduction,resolution and illumination of cold light source system.
