摘要:
An imaging system and method include a medical device (102) having a tracking element (106) mounted thereon. An array (109) of transducers is spaced apart from one another for exchanging energy in a subject between tracking element and the array of transducers. A trilateration module (104) is configured to interpret signals sensed between tracking element and the array of transducers to compute times of flight of signals associated with the transducers in the array such that a position of tracking element is determined in at least two dimensions to locate a position of the medical device in a visual image.
