Advanced Medical Electronics (AME) proposes to demonstrate the feasibility of using infrared (IR) microbolometer imaging technology on the distal tip of a flexible endoscope to accurately measure internal temperatures during surgical heat treatments. The phase II goal is to provide real-time spatially accurate two-dimensional surface temperature measurements through a flexible endoscope. The proposed endoscope is needed both for measuring temperature in the abdomen during percutaneous thermal treatment of tumors and for endoscopic thermal treatment of surface tissue diseases (i.e. esophageal varices). The proposed device is needed to support new technologies that can effectively treat tumors and surface tissue diseases quickly and effectively. These techniques require accurate real-time measurements of adjacent surface tissue temperatures. Recent microbolometer packaging advances at Honeywell (a partner on the proposed project) that will allow a 2.5 x 2.5 mm IR imaging camera to be created and make this proposed project possible. An available microbolometer based IR camera will be optically and electrically modified to emulate the calculated performance of the proposed endoscope scale camera. The University of Minnesota will conduct animal tests to demonstrate the feasibility of using the proposed system in surgical procedures. In phase II, microbolometer arrays will be fabricated into endoscope camera assemblies. PROPOSED COMMERCIAL APPLICATIONS: The commercial application of the flexible IR endoscope is tied with the growing marketplace of heat treatment technology. It is believed that the flexible IR endoscope would become an essential part of the equipment needed to perform these procedures.

Advanced Medical Electronics（AME）提议证明在柔性内窥镜的远端使用红外（IR）微光仪成像技术的可行性，以在手术热处理期间准确测量内部温度。 II期目标是通过柔性内窥镜提供实时精确的二维表面温度测量。拟议的内窥镜既需要在肿瘤的经皮热处理和表面组织疾病的内窥镜热处理（即食管静脉曲张）的内窥镜热处理过程中测量腹部温度。需要该设备来支持可以有效治疗肿瘤和表面组织疾病的新技术。这些技术需要对相邻表面组织温度进行准确的实时测量。霍尼韦尔（拟议项目的合作伙伴）的最新微型仪包装进步将允许创建2.5 x 2.5 mm的IR成像摄像头，并使该提议的项目成为可能。可用的基于微晶的IR摄像机将进行光学和电修改，以模拟所提出的内窥镜刻度摄像头的计算性能。明尼苏达大学将进行动物测试，以证明在手术程序中使用拟议系统的可行性。在II阶段，微量仪阵列将被制成内窥镜摄像头组件。拟议的商业应用：柔性红外内窥镜的商业应用与热处理技术的不断增长的市场相关。人们认为，灵活的红外内窥镜将成为执行这些程序所需的设备的重要组成部分。
