Design For Control System Of Mammography Based On STM32

The common breast diseases mainly include the following four categories:Breast congenital malformations, inflammatory disease of Mastitis, Breast hyperplasiaand cystic hyperplasia disease, Disease of breast tumor and so on. In these fourcategories of breast disease, the greatest threat to human health is the malignanttumor-Mammary cancer, mammary cancer is one of the most common malignanttumors in women, the incidence of mammary cancer accounts for the entire6-11%in avariety of malignant tumors, and it has become the main cause of threat to women’shealth. Around the world each year about1500000people are diagnosed withmammary cancer, about600000people die of the disease. In the past20-30years, X-ray photography of breast has become the most sensitive technology thatdetection of breast diseases that can not be touched, at present more and morehospitals of domestic have introduced X-ray equipment of breast。Mammography is the most simple, the most reliable machine of detection, itsmain function is to produce the X-ray image, record and analysis the image, so thatdetect and diagnose of breast disease, if use mammography to achieve X-ray imagethat the pain is relatively light, and the image is high resolution, good repeatability thatimage that taken Can be contrasted, and you also needn’t to consider the age and size.According to the function will be achieved by mammography, the paper designeda control system of breast machine, this system consists of four parts, the main controlpart, display part, pressure acquisition part, PC part, wherein, the first three parts, areintroduced in this paper, including its hardware structure, software design, selectionand peripheral device, are introduced in detail, and PC part is rough introducedaccording to its function.In the whole system, the main control part is the core part, leading the global, itnot only dominates all the peripheral devices, including the stepper motor, AC motor,electric putter, high voltage generator, tube, detector, manual button, Pedal button andother peripheral devices, but also to use its own five serial ports and some timerscoordinate of the display part, pressure acquisition part and the part of host computer.Display part plays the auxiliary key function, keeps the system data, including thevalue of C arm height, angle of rotation C arm, depressor height, and the exposure parameters, and these parameters accurately displayed on the LCD screen, at the sametime, also you can control the angle of C arm through the button of touch screen.Adjust the exposure parameters. The main function of oppression is to collect thecompressor pressure value.
