System and method for navigating an ultrasound catheter to image a beating heart
First Claim
Patent Images
1. A system for navigating an ultrasound catheter to image a beating heart, comprising:
- a catheter carrying an ultrasonic transducer configured to generate a sound wave and sense an echo wave to obtain ultrasound data for a first portion of the interior surface of the heart and a sensor element configured to generate a signal indicative of a position of the first portion; and
,an imaging system for simultaneously displaying an ultrasound image of the first portion and a three-dimensional context map of the heart and simultaneously highlighting a first surface on the context map corresponding to the first portion and a second surface on the context map corresponding to a second portion of the interior surface of the heart for which ultrasound data was previously captured by the ultrasonic transducer.

15. A method of navigating an ultrasound catheter to image a beating heart, comprising the steps of:
-
positioning a catheter in the interior of the heart, the catheter carrying an ultrasonic transducer and a sensor element; determining a position of the sensor element; generating a sound wave and sensing an echo wave to obtain ultrasound data for a first portion of the interior surface of the heart; and
,simultaneously displaying an ultrasound image of the first portion and a three-dimensional context map of the heart and simultaneously highlighting a first surface on the context map corresponding to the first portion and a second surface on the context map corresponding to a second portion on the interior surface of the heart for which ultrasound data was previously captured by the ultrasonic transducer. - View Dependent Claims (16, 17, 18, 19)
