Abstract :
A structure is proposed for fabricating a portable prototype apparatus, using the embedded control technique based on ARM core, which has a simple structure and small size. The hardware is easily updated and maintained due to its modular structure, the software has a visualized interface and hierarchical design mode, so the apparatus has a good peculiarity like compact structure and control. Moreover, the build-in PID algorithm for temperature control and the power driver element for ultrasonic output power have been optimized the experiment results demonstrate that using this structure and optimization method. Due to the speed of data collecting by parallel interface is much quick than the speed of data collecting by serial interface, so a reliable performance of this apparatus can be achieved, which can meet with the need of clinical application.
