Abstract

An electroanatomical mapping system tracks and visualizes an item of interest, such as a medical device or anatomical structure, as the item moves within a non-ionizing localization field. The system localizes the item within the localization field and determines the initial position of the item with respect to an imaging device (e.g., an intracardiac echocardiography catheter) field of view. The system displays a region of the field of view containing the initial position of the item if it is within the field of view. If not, the system can output a notification. As the item moves, the system can update the displayed region so that it remains focused on the item, and can output a notification if the item exits the field of view. The displayed region(s) can include one or more two-dimensional image slices, optionally output as a three-dimensional volumetric image.

Claims (27)

1 . A method of tracking a medical device within a non-ionizing localization field using an electroanatomical mapping system, the method comprising the electroanatomical mapping system:

localizing the medical device within the non-ionizing localization field;

localizing an intracardiac echocardiography catheter within the non-ionizing localization field;

determining a coordinate envelope of a field of view of the intracardiac echocardiography catheter from the localization of the intracardiac echocardiography catheter;

making an initial determination whether or not the medical device falls within the coordinate envelope of the field of view of the intracardiac echocardiography catheter; and

when the initial determination is that the medical device falls within the coordinate envelope of the field of view, displaying a region of the field of view containing the medical device.

2 . The method according to claim 1 , further comprising, when the initial determination is that the medical device does not fall within the coordinate envelope of the field of view, outputting a negative imaging notification.

3 . The method according to claim 1 , wherein the region of the field of view includes a two-dimensional image slice.

4 . The method according to claim 3 , wherein the region of the field of view includes a plurality of adjacent two-dimensional image slices.

5 . The method according to claim 4 , wherein the plurality of adjacent two-dimensional slices are displayed as a volumetric image.

6 . The method according to claim 1 , further comprising the electroanatomical mapping system:

determining that the medical device has moved to a new location within the field of view; and

displaying an updated region of the field of view containing the new location of the medical device.

7 . The method according to claim 1 , further comprising the electroanatomical mapping system:

determining that the medical device has moved to a new location outside of the field of view; and

outputting a negative imaging notification.

8 . The method according to claim 1 , wherein displaying the region of the field of view containing the medical device comprises initializing a display of the region of the field of view containing the medical device.

9 . An electroanatomical mapping system for tracking a medical device within a non-ionizing localization field, the system comprising:

a display; and

a processor configured to:

localize the medical device within the non-ionizing localization field;

localize an intracardiac echocardiography catheter within the non-ionizing localization field;

determine a coordinate envelope of a field of view of the intracardiac echocardiography catheter from the localization of the intracardiac echocardiography catheter;

make an initial determination whether or not the medical device falls within the coordinate envelope of the field of view of the intracardiac echocardiography catheter; and

output to the display a region of the field of view containing the medical device when the initial determination is that the medical device falls within the coordinate envelope of the field of view.

10 . The electroanatomical mapping system according to claim 9 , wherein the processor is further configured to output a negative imaging notification upon making a subsequent determination that the medical device does not fall within the field of view.

11 . The electroanatomical mapping system according to claim 9 , wherein the output comprises an initialized region of the field of view containing the medical device.
