Abstract
A method for minimizing tracking system interference caused by a motor driven ultrasonic imaging device is disclosed herein. The method includes providing an ultrasonic imaging device adapted to obtain a generally real time three-dimensional image. The ultrasonic imaging device includes a motor configured to rotate a transducer array within a catheter housing. The method for minimizing tracking system interference also includes estimating a noise signal produced by the motor, selecting a tracking system signal strength and/or frequency adapted to minimize a tracking system interference, and implementing a field generator to produce a tracking system signal at the selected tracking system signal strength and/or frequency.
