Paper Abstract

Lack of haptic feedback during laser surgery hampers controlling the incision depth, leading to a high risk of undesired tissue damage. Here we present a new feedback sensing method that accomplishes non-contact realtime monitoring of laser ablation procedures by detecting shock waves emanating from the ablation spot with air-coupled transducers. Experiments in soft and hard tissue samples attained high reproducibity in real-time depth estimation of the laser-induced cuts. The advantages derived from the non-contact nature of the suggested monitoring approach are expected to greatly promote the general applicability of laser-based surgeries.
