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.
白癜风在临床上较为常见。它是一种获得性、持续性皮肤和黏膜色素脱失性疾病。高能超声作为一种非侵入性、非放射性的治疗方法，已应用于白癜风的皮肤疾病治疗中，取得了良好的临床效果。本文分析了原始医用超声系统治疗白癜风的结构，发现了系统的不足之处和缺失的组件。在原始设计方案的基础上，设计了新的结构方案，解决了原始系统的缺点，并增加了缺失的部分。随后，根据实际应用的要求和具体组件的性能，具体介绍了原理图设计，包括音频和视频的输入、输出和存储、DDR3、以太网以及电源模块等关键电路的设计。之后，在 PCB 设计中，详细介绍了包括堆叠、布局、布线和关键信号模拟的内容。该设计包括探头激励信号产生模块、激励信号参数控制模块、高压和温度监测模块以及相应的功率转换模块。本文主要是基于成本和性能的原则，开发一种用于白癜风皮肤疾病加热治疗的阵列系统。本文基于 FFD 模型的非刚性配准算法和 HPV 插值以及结合形状信息和 SIFT 方法的非刚性配准算法，在聚焦超声治疗系统中实现了图像引导定位和监测功能。研究表明，当发射器电路的峰值电压为 55V 时，声功率为 0.28W。由此可见，本文设计的发射电路系统是一个相对稳定可靠的系统，适用于白癜风皮肤疾病的超声治疗。
