[Abstract]:With the rapid development of Internet technology, mobile devices have gradually become an indispensable tool in human life. With the support of various kinds of App, mobile devices can have a variety of functions. Therefore, this subject combines the traditional medical ultrasonic probe with the mobile phone in daily life, so that the mobile device can be used as the data display terminal of the wireless probe. In this paper, a wireless ultrasonic probe is proposed to replace the traditional wired probe as a medical device to detect the patient's condition at any time, and it is convenient for the doctor or user to operate, which greatly simplifies the work of the doctor. The combination of mobile phone and medical ultrasonic acquisition equipment will bring a substantial breakthrough for the medical industry. In the last section, the abstract is condensed into one page. This subject mainly implements a portable wireless ultrasonic probe data transmission system and the whole software system. The Android software is developed for image observation by mobile phone, and ultrasonic data processing is carried out on the mobile phone. Use database to save user information. This thesis is divided into four parts: the whole data transmission flow and the whole software frame are introduced, and the development tools used in the development process are introduced, and the data transfer from acquisition to DDR memory is realized by building DMA module. The embedded software is developed in the ZYNQ development board to realize the ultrasonic data sending end and the receiving end of ultrasonic parameters, and the Android software is developed in the mobile phone to realize all kinds of functions needed by the ultrasonic display terminal. Firstly, this paper introduces the flow of the whole data transmission, the framework of embedded software and Android software, the development tools needed in the development process, the construction of the development environment and so on. Secondly, this paper completes the construction of DMA transmission path by Vivado software and generates system.bit to configure the hardware environment of the development board when BOOT.bin starts, completes the preparation of DMA driver, and provides hardware support for ultrasonic data transmission. The collected ultrasonic data is transferred through DMA to DDR memory of the development board, and the data transmission process is realized in the hardware platform. Then, in this project, we build the embedded Linux system in the development board, complete the compilation and transplantation of the related drivers, build the socket server, and complete the mapping between virtual address and DDR memory. Through wireless transmission, the data in memory is sent to the mobile phone. At the same time, the receiver of ultrasonic parameters is set up, and the driver to distribute the parameters to the register is written to realize the function of parameter downloading. In order to combine the ultrasonic probe with the mobile phone, this paper develops the Android software on the mobile phone to realize the data receiving, completes the ultrasonic data processing module with C in the JNI layer, and completes the display of the interface in the Android layer. And finish the design of interface. In order to facilitate the doctors and patients to debug the probe, the ultrasonic parameter debugging interface is designed in the mobile phone, and the wireless transmission is used to complete the download of the parameters, and to realize the function of receiving and distributing the ultrasonic parameters at the development board; at the same time, The open source database Litepalis is used to save patient information, to facilitate doctors to observe the patient's condition and record patient information at any time.
