Three-dimensional tracking and imaging system |
February 1, 2000 |
| A 3-D tracking and imaging system (1600) for tracking the position of a surgical instrument (e.g., a catheter, probe, a sensor, needle or the like) inserted into a body, and displaying a 3-D image showing the position of the surgical instrument in reference to a 3-D image of the envi |

Ultrasound-based 3-D tracking system using a digital signal processor |
July 14, 1998 |
| A system for determining a time delay of a signal propagating through a medium. The time delay is used to determine the distance between transducers arrangable within a body. One or more Digital Signal Processors (DSP) are programmed to recognize various waveform patterns by matching |
