All-digital B-type Ultrasonic Diagnostic Apparatus System Structure

With the development of Ultrasonic theory and technology, Ultrasonic devices are updating unceasingly. Ultrasonic Diagnoses has been an important means of forecast, estimate and cure diseases. Compare with some powerful overseas Corp., domestic factories which produce Ultrasonic Diagnostic Equipment are lack of competition.The thesis is to accomplish a Digital B-Node Ultrasonic Diagnostic Equipment based on ARM9 and Embedded Linux. It will supply high distinguish power and high penetrability clinic diagnose images. The device will offer movie-review and image management system, and then become a humanistic Ultrasonic Equipment with complete function.Firstly, the thesis expatiates the researching status of the medical instrument and the embedded system, thereby gives out the researching content and target. And then, the thesis deeply analyses the hardware system structure. After the description of the main frame and dual-core structure, the thesis introduces the communicating interfaces and the working process of the CPU module and the FPGA module. Afterwards, based on the hardware platform of ARM9, the thesis elucidates the developing processes of the Linux Embedded Operating System and the application software, as well as the MiniGUI software platform which carried out the application software structure of the B-Node Ultrasonic Diagnostic Equipment, and gives out the design method of actual modules in details, provides the software flow chart. The last part of the thesis, the conclusion and prospect of the whole system are given.
