1. A method comprising: imaging a first cavity portion of a greater body cavity using a first imaging sensor of a catheter to generate a first digital image; imaging a second cavity portion of the greater body cavity using a second imaging sensor of the catheter to generate a second digital image; wherein the first and second cavity portions are contiguous portions of the greater body cavity, and wherein first and second images partially overlap in an overlap portion; and generating a greater image of the greater body cavity from at least the first and second digital images; the generating including identifying the overlap portion in the first image, identifying the overlap portion in the second image, and using the identified overlap portion to combine the first and second images to generate the greater image.
