Study On The Control System Of Film Exposure Device Of Medical X-ray Machine

After the discovery of X-ray, medical X-ray is made according to the feature of X-ray. Because of its diagnostic,efficient and convenient features, medical X-ray machine currently in the clinical application is already very popular and has become the major medical equipment of the visual diagnosis and treatment. However, the film exposure device of the currently widespread-used X-ray machine has poor quality of image, a low level of automation, poor precision controlled and film exposure and large size.To the shortcoming of film exposure device, the study paper clings to the key technological problems that are around increasing the precision controlled of the film exposure device and the level of the automation, launches the study and design systematically.The main research contents are as follows:①introduced the discovery, nature of X-ray and the birth of the medical X-ray machine, the structural composition of the medical X-ray machine, analyzed the situation of the medical X-ray exposing technology both at home and abroad at present, and also has presented the purpose, meaning and content of the research.②analyzed the work principle, design requirements of the film exposure device, introduced the composition and work principle of the mechanical structure, on the base of them, presented to the design methodology regarding microcontrollers as the core intelligent control system, expounded the overall design programme of the film exposure device control system in the hardware and software.③elaborately expounded the interface design and the design programme of control system in the operation desk in the hardware and software.④analyzed the factor that impacts the precision of boards sheltering X-ray, expounded the design programme using the switch limiting position for the position of boards sheltering X-ray, introduced the mechanical composition and work principle in the system, elaborately expounded the design programme of control system in the operation desk in the hardware and software.⑤analyzed the factor that impacts the precision of of film car, expouded the design programme using the switch limiting position for the position of film car, introduced the mechanical composition and work principle in the system, elaborately...
