Medical technologies have undergone significant development to overcome the problems inherent in minimally invasive surgery such as inhibited manual dexterity, reduced visual information, and lack of direct touch feedback to make it easier for surgeons to operate. A minimally invasive tool incorporating haptic feedback is being developed to increase the effectiveness of diagnostic procedures by providing force feedback. Magnetic resonance imaging guidance is possible to allow tool localization; however, this engenders the requirement of magnetic resonance compatibility on the device. This paper describes the work done towards developing a sensing device using piezoelectric sensor elements to locate subsurface inclusions in soft substrates, with its magnetic resonance compatibility tested in a 1.5 T scanner. Results show that the position of a hard inclusion can be determined.
医学技术已经历了重大发展，以克服微创手术中固有的问题，如手动灵活性受限、视觉信息减少以及缺乏直接的触觉反馈，从而使外科医生更容易操作。一种结合触觉反馈的微创工具正在被开发，以通过提供力反馈来提高诊断程序的有效性。磁共振成像引导可以实现工具定位；然而，这就要求设备具备磁共振兼容性。本文描述了利用压电传感器元件开发一种传感装置以定位软质基底中地下内含物的工作，并在1.5T扫描仪中对其磁共振兼容性进行了测试。结果表明，可以确定硬质内含物的位置。
