摘　　要：神经系统疾病逐渐成为危害人体健康的重要疾病之一。神经组织的高精度实时成像及可视化引导,将为神经系统疾病的早期诊断及术中的精准治疗提供重要的安全保障。本文简介了国内外超声成像技术与电容式超声换能器(c MUT)的研究进展,提出将实时超声成像c MUT阵列器件与神经微电极阵列单片集成的技术方案。采用双稳态超声共振模式,c MUT阵列器件可实现低频与高频共振间的模式切换,进而兼顾超声可视化检测深度和成像分辨率,实现对神经损伤、神经卡压及神经肿瘤等神经系统疾病修复与复位的可视化引导。Nervous system disease has become one of the major diseases that do harm to human health. High precision realtime imaging and visualization of nerve tissue provide a higher possibility for the early diagnosis of nervous system disease and precision treatment. The developments of ultrasonic imaging technology and capacitive micromachined ultrasonic transducers （cMUT） were summarized in the paper. The technology of the integration of real-time ultrasound imaging cMUT array device and neural microelectrode array was proposed. Based on the bi-stable ultrasound resonance, cMUT array device can switch between low-frequency mode and high-frequency mode, and enhance visual inspection depth and imaging resolution, offering the real-time visual guidance for the recovery and restoration of neural injury, neural compression, neural tumour and other neurological diseases.
