1. A 3-D tracking and imaging system, comprising:
- a plurality of mobile transducer means mounted to an instrument means;
at least one reference transducer means for establishing a reference frame relative to said plurality of mobile transducer means;
coordinate generation means for generating three-dimensional coordinates of the plurality of mobile transducers relative to the reference frame established by the at least one reference transducer means;
imaging modality means for generating one or more digital images of the environment surrounding the instrument means;
image registration means for receiving the three-dimensional coordinates and the one or more digital images, and generating one or more 3-D composites evidencing the position of the plurality of mobile transducer means in relation to the one or more digital images; and
display means adapted for displaying one or more 3-D composites.

Abstract
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 environment surrounding the surgical instrument. The 3-D tracking and imaging system (1600) aiding a physician in the guidance of the surgical instrument inside the body.

12. A 3-D tracking and imaging system comprising:
-
a plurality of transducer means mounted to an instrument means; one or more transducer means located at fixed positions to establish a reference frame relative to the plurality of transducer means mounted to the instrument means; coordinate generation means for generating three-dimensional coordinates of the plurality of transducers mounted to an instrument means relative to the reference frame established by the one or more transducer means located at fixed positions; imaging modality means for generating image data showing an environment surrounding the instrument means; image registration means for registering the three-dimensional coordinates in the image generated by the imaging modality means to generate a 3-D image scene showing the location of the plurality of transducer means mounted to the instrument means in relation to the image data; and display means for displaying the 3-D image scene. - View Dependent Claims (13, 14, 15, 16)

17. A method of tracking an instrument inside a medium within a body and imaging the environment surrounding the instrument in the body, comprising:
-
mounting a plurality of transducer means to an instrument means; locating at least one transducer means at fixed positions to establish a reference frame relative to the plurality of transducer means mounted to the instrument means; generating three-dimensional coordinates of the plurality of transducer mounted to the instrument means relative to the reference frame established by the transducer means located at fixed positions; generating image data showing an environment surrounding the instrument means; registering the three-dimensional coordinates with the image data to form a 3-D image scene showing the location of the plurality of transducer means mounted to the instrument means relative to the image data; and displaying the 3-D image scene. - View Dependent Claims (18, 19, 20)
