我们开发了一种内窥镜回声探头，可以通过具有3.5毫米通道的柔性光纤或视频内窥镜的活检通道。探头在内窥镜直视下沿着胃肠道壁移动。平移扫描动作由位置电位器感应，并与超声b模回波结合产生墙壁的横截面图像。该系统使用20兆赫的超声波频率来产生高分辨率图像。该装置用于犬体外和体内胃肠组织的内镜成像。肠壁的超声图像与组织学结构相关。这种探头克服了与目前使用的联合超声内窥镜相关的一些问题。将探头与视频内窥镜配合使用，可以同时显示内窥镜和超声图像，简化了两种技术的协调应用。
We developed an endoscopic echo probe that can be passed via the biopsy channel of a flexible fiberoptic or video endoscope with a 3.5-mm channel. The probe moves along the gastrointestinal wall under direct endoscopic vision. The translational scanning action is sensed by a position potentiometer and combines with the ultrasonic B-mode echoes to produce a cross-sectional image of the wall. The system uses an ultrasound frequency of 20 MHz to produce high-resolution images. The device was used to image canine gastrointestinal tissue in vitro and in vivo during endoscopy. Ultrasound images of the gut wall correlate with histologic structure. This probe overcomes some of the problems associated with the combined ultrasound endoscopes now in use. Use of the probe with video endoscopy allows the endoscopic and ultrasound images to be displayed side by side, simplifying coordination of application of the two techniques.
