Abstract

Vitiligo is relatively common clinically. It is an acquired and persistent skin and mucosal pigment depigmentation disease. As a noninvasive and nonradioactive treatment, high-energy ultrasound has been applied to skin diseases of vitiligo. Treatment achieved good clinical results. This article analyzes the structure of the original medical ultrasound system for vitiligo and finds the deficiencies and missing components of the system. On the basis of the original design scheme, a new structural scheme was designed, which solved the shortcomings of the original system and added missing parts. Subsequently, according to actual application requirements and specific component performance, the schematic design, including audio and video input, output and storage, DDR3, Ethernet, and the design of key circuits, such as power supply modules, are specifically introduced. Later, in the PCB design, the contents including stacking, layout, routing, and simulation of key signals were introduced in detail. The design includes a probe excitation signal generation module, excitation signal parameter control module, high voltage and temperature monitoring module, and corresponding power conversion module. This paper is mainly to develop a vitiligo skin disease heating treatment array system based on the principle of both cost and performance. This paper is based on the nonrigid registration algorithm of the FFD model and HPV interpolation and the nonrigid registration algorithm combining shape information and SIFT method. In the focused ultrasound treatment system, the image-guided positioning and monitoring functions are realized. Studies have shown that when the peak voltage of the transmitter circuit is 55 V, the sound power is 0.28 W. It can be seen that the transmitting circuit system designed in this article is a relatively stable and reliable system, which is suitable for the ultrasound treatment of vitiligo skin diseases.
