Comparison of <i>in vivo</i> experimental and simulated results.

(a) A pathological section after dual-fiber laser ablation. Four regions were generally observed: a cavitation region containing the fibers, a carbonization region between the fibers, a pale region of inactivated tissue, and the edema cincture interfacing with normal tissues (b) A pathological section after single fiber laser ablation. (c) H&E staining of normal zone. (d) H&E staining of ablated tissue.
