This study proposes an additional feature of optical coherence tomography (OCT) as a guidance system for laser surgery. aiming to enhance ablation efficiency during laser osteotomy. A long-range Bessel-like beam OCT system is integrated with an Er:YAG laser. The signal sensitivity of the OCT system is measured under various conditions encountered during laser osteotomy. https://www.bekindtopets.com/mega-price-Quick-Sling-Rafter-Mount-System-with-H-Bracket-top-buy/
