Systems and Methods for Guiding a Medical Instrument

摘要

A virtual tracking system for a virtual medical device. The virtual medical device may include a tangible proximal portion that at least temporarily has a magnetic element attached thereto. The system includes a tracking circuit configured to track movement of the virtual medical device and a display. The tracking circuit may include at least one reception component configured to detect a magnetic field of the magnetic element and to generate magnetic field strength data. The tracking circuit may also include a processor that iteratively computes position data of a virtual distal portion of the virtual medical device according to the magnetic field strength data so as to simulate insertion of the virtual distal portion of the virtual medical device into a body of a patient. The display may be configured to depict an image of the computed position data of the virtual distal portion of the virtual medical device.
