Abstract

A method of imaging a tissue region may comprise visualizing lesions over a tissue region via an imaging catheter by viewing the tissue region through a viewing region purged by a fluid and identifying, with a computer, a location of each of the lesions relative to one another over the tissue region. The method may also include registering, with the computer, a unique set of ablation parameters received from a treatment device for lesion generation for each of the lesions and generating, with the computer, a map of the lesions based on the identified locations of the lesions. The method may also include visually displaying the map of the lesions in a common display with a real-time field of view image of a first lesion; and visually displaying the registered unique set of ablation parameters for the first lesion with the real-time field of view image of the first lesion.

Claims

1. A method of imaging a tissue region, comprising:

visualizing a plurality of lesions over a tissue region within a body via an imaging catheter by viewing the tissue region through a viewing region purged of blood by a fluid;

identifying, with a computer, a location of each of the plurality of lesions relative to one another over the tissue region;

registering, with the computer, a unique set of ablation parameters received from a treatment device for lesion generation for each of the plurality of lesions;

generating, with the computer, a map of the plurality of lesions based on the identified locations of the plurality of lesions;

visually displaying the map of the plurality of lesions in a common display with a real-time field of view image of a first lesion of the plurality of lesions; and

visually displaying the registered unique set of ablation parameters for the first lesion of the plurality of lesions with the real-time field of view image of the first lesion of the plurality of lesions.

2. The method of claim 1 wherein the visualizing comprises visualizing cardiac tissue within a chamber of a heart.

3. The method of claim 1 further comprising displaying a direction indicator with the real-time field of view image of the first lesion, the direction indicator indicating a direction from the first lesion to a second lesion of the plurality of lesions.

4. The method of claim 3, wherein the direction indicator is a first direction indicator and further comprising displaying a second direction indicator with a real-time field of view image of the second lesion, the first direction indicator indicating a different direction than the second direction indicator.

5. The method of claim 1, wherein the real-time field of view image is of a viewing field surrounded by an open hood coupled to the imaging catheter.
