项目摘要

DESCRIPTION: An ultrasonic diagnostic apparatus has been proposed for Dental applications in determining tooth pathologies such as demineralization/caries, hidden fractures, and formation of abscesses. The equipment adopts a piezoelectric and laser optic hybrid transduction system for interrogation of teeth. Ultrasonic responses of the tooth structure will be analyzed by a pattern recognition expert system (artificial intelligence) to determine the diagnosis of the tooth inspected. The proposed research will eventually help to reduce the use of harmful X-ray radiation in Dental clinics and contribute to artificial intelligence based diagnosis. The proposed concept has been successfully demonstrated in the previous Phase I study. In this Phase II study, instrumentation for clinical data collection using a combination of conventional piezoelectric and new laser-based ultrasonic technologies will be developed and optimized; an artificial intelligence based diagnostic function will be developed using clinical data and implemented using embedded computing; numerical simulations will be used to enhance diagnostic function development; and finally, initial clinical trials will be conducted to demonstrate the performance of the prototype equipment. The ultrasonic apparatus for Dental diagnosis outlined in this application is a first application of AI-based NDE in Dentistry. The research concept may also extend to periodontal and craniofacial applications.

描述：提出了一种超声诊断设备，用于确定牙齿病理，如脱矿/龋齿，隐藏骨折和脓肿的形成。该设备采用压电和激光光学混合转导系统对牙齿进行问诊。牙齿结构的超声响应将通过模式识别专家系统（人工智能）进行分析，以确定被检查牙齿的诊断。这项拟议中的研究最终将有助于减少牙科诊所使用有害的x射线辐射，并有助于基于人工智能的诊断。建议的概念已在先前的第一阶段研究中成功证明。在这项II期研究中，将开发和优化用于临床数据收集的仪器，该仪器使用传统压电和新型基于激光的超声波技术相结合；将利用临床数据开发基于人工智能的诊断功能，并使用嵌入式计算实现；数值模拟将用于增强诊断功能的开发；最后，将进行初步临床试验，以证明原型设备的性能。本应用概述的用于牙科诊断的超声设备是基于人工智能的濒死体验在牙科中的首次应用。研究概念也可扩展到牙周和颅面应用。
