A method for carrying out a medical procedure using a 3-D tracking and imaging system (1600). A surgical instrument, such as a catheter, probe, sensor, needle or the like is inserted into a living being, and the position of the surgical instrument is tracked as it moves through a medium in a bodily
A method for carrying out a medical procedure using a 3-D tracking and imaging system (1600). A surgical instrument, such as a catheter, probe, sensor, needle or the like is inserted into a living being, and the position of the surgical instrument is tracked as it moves through a medium in a bodily structure. The location of the surgical instrument relative to its immediate surroundings is displayed to improve a physician's ability to precisely position the surgical instrument. The medical procedures including removal of an obstruction from the circulatory system, a biopsy, amniocentesis, brain surgery, measurement of cervical dilation, evaluation of knee stability, assessment of myocardial contractibility, eye surgery, prostate surgery and transmyocardial myocardial revascularization (TMR). In addition, the method of the present invention also finds use in connection with the generation of 2-D echo planes.
[ The invention claimed is:] [1.] A method of performing an in vivo medical procedure on an associated body using a 3-D tracking and imaging system, said method comprising:mounting a plurality of mobile transducer means to an instrument means;mounting one or more reference transducers means to locat
[ The invention claimed is:] [1.] A method of performing an in vivo medical procedure on an associated body using a 3-D tracking and imaging system, said method comprising:mounting a plurality of mobile transducer means to an instrument means;mounting one or more reference transducers means to locations on the body, the reference transducer means having a position fixed relative to the body;generating three-dimensional coordinates of the mobile transducer means relative to a reference frame established by the reference transducer means;generating image data of the environment surrounding the instrument means to provide an image template;registering the three-dimensional coordinates with the image data to form a 3-D image scene showing the position of the mobile transducer means relative to the image template.
