Abstract
Catheter navigation is coupled with ultrasound imaging to yield a context map showing the location on a heart of the ultrasonically imaged frame.
Claims20
A system for imaging a heart, comprising:
- a signal processing system configured to:
- receive ultrasound data and position data from a catheter, the ultrasound data including an ultrasonic image of a first portion of an interior surface of the heart and the position data including data associated with a location of the catheter within the heart;
- and,
- transmit imaging data to a display responsive to the ultrasound data and the position data, the imaging data configured to cause the display to simultaneously display the ultrasound image of the first portion of the interior surface of the heart and a three-dimensional context map of the heart and simultaneously highlight a first surface on the context map corresponding to the first portion of the interior surface of the heart 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 received.
1 more element
A system for imaging a heart, comprising:
- a signal processing system including:
- means for receiving ultrasound data from an ultrasonic transducer disposed on a catheter, the ultrasound data including an ultrasonic image of a first portion of an interior surface of the heart;
- means for receiving position data from a first sensor element disposed on the catheter, the position data including data associated with a location of the catheter within the heart;
- and,
- means for transmitting imaging data to a display responsive to the ultrasound data and the position data, the imaging data configured to cause the display to simultaneously display the ultrasound image of the first portion of the interior surface of the heart and a three-dimensional context map of the heart and simultaneously highlight a first surface on the context map corresponding to the first portion of the interior surface of the heart 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 received.
2 more elements
A method for displaying images of a heart, comprising:
- receiving a first set of ultrasound data and a first set of position data from a catheter, the first set of ultrasound data including an ultrasound image of a first portion of an interior surface of the heart and the first set of position data including data associated with a location of the catheter within the heart;
- and,
- transmitting a first set of imaging data to a display responsive to the first set of ultrasound data and the first set of position data, the first set of imaging data configured to cause the display to simultaneously display the ultrasound image of the first portion of the interior surface of the heart and a three-dimensional context map of the heart and simultaneously highlight a first surface on the context map corresponding to the first portion of the interior surface of the heart 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 received.
