Figure 3 While the gelatin nodule (indicated by arrows) in the swine lung seemed to be completely ablated, the surrounding lung tissue was ablated only a little. The peripheral edge of the gelatin nodule (marked by the star) sometimes remained nonablated CHEST 2005 127, 973-977DOI: (10.1378/chest.127.3.973) Copyright © 2005 The American College of Chest Physicians Terms and Conditions

Cavities within the ablated region were filled with a while silicone rubber, indicating the communication with surrounding bronchi CHEST 2005 127, 973-977DOI: (10.1378/chest.127.3.973) Copyright © 2005 The American College of Chest Physicians Terms and Conditions
