Abstract
A portable measurement system is provided comprising a probe, two trackers, a receiver and a pod. A user interface control captures a location and position of the probe in a three-dimensional sensing space with respect to a coordinate system of the receiver from time of flight waveform analysis. The system suppresses a ringing portion of the received ultrasonic and minimizes distortion associated with ultrasonic transducer ring-down during high-resolution position tracking of the probe and the two trackers. Media is presented according to a customized use of the probe and two trackers during an operation workflow.
