Three ablation and imaging scenarios used to test 3-D imaging of ablation lesions. (A) Lesion pairs. The spacing between the ablation sites was controlled by a translation stage. The AcuNav (blue cylinder) imaged directly forward, and the tissue sample was translated laterally and in elevation to scan the volume (the “linear-translated” scan). (B) Lesion line. The spacing between lesions was controlled. The AcuNav had a 45° lateral field of view, and was translated in the elevation plane (the “phased-translated” scan). (C) “X” ablation. One ablation was created from the endocardial surface, one from the epicardial surface, and one from both. The AcuNav had a 45° lateral field of view, and was rotated to cover a 180° elevational field of view (the “phased-rotated” scan).
