摘要： An invasive probe for mapping the walls of a lumen employs a real-time tracking means and a wall distance measurement means. As the probe is advanced within the lumen, the real-time tracking means provides three-dimensional coordinates of the probe's position and orientation. Concurrent with probe localization, the distance between the probe and the lumen walls is measured. Both the probe position and the wall distance measurement are sent to a data acquisition system which in turn provides a graphic or numeric display to the operator. Probe tracking can be performed with radio-frequency, magnetic resonance, ultrasonic techniques or the like. If desired, lumen wall distance measurements can be performed with magnetic resonance or ultrasound methods. Lumen wall distance measurements can also be performed with mechanical devices such as balloons and/or expanding structures.

摘要翻译： 用于映射管腔壁的入侵探针采用实时跟踪装置和壁距测量装置。 当探头在管腔内前进时，实时跟踪装置提供探头位置和方位的三维坐标。 与探头定位同时测量探头与腔壁之间的距离。 探头位置和墙壁距离测量都发送到数据采集系统，该系统又向操作员提供图形或数字显示。 可以使用射频，磁共振，超声波技术等进行探测跟踪。 如果需要，可以用磁共振或超声波方法进行管腔壁距离测量。 腔壁距离测量也可以用诸如球囊和/或膨胀结构的机械装置进行。
