Download or read book Comparison of Soft and Hard Tissue Ablation with Sub ps and Ns Pulse Lasers written by and published by . This book was released on 1996 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tissue ablation with ultrashort laser pulses offers several unique advantages. The nonlinear energy deposition is insensitive to tissue type, allowing this tool to be used for soft and hard tissue ablation. The localized energy deposition lead to precise ablation depth and minimal collateral damage. This paper reports on efforts to study and demonstrate tissue ablation using an ultrashort pulse laser. Ablation efficiency and extent of collateral damage for 0.3 ps and 1000 ps duration laser pulses are compared. Temperature measurements of the rear surface of a tooth section is also presented.

This book was released on 2006 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamics of laser osteotomy in a liquid environment was explored. The underlying mechanisms during liquid-assisted ablation included rapid vaporization, plasma confinement, and cavitation with jet formation. Compared to direct ablation, the liquid-confined ablation with higher ablation volume and augmented acoustic excitation demonstrated the feasibility of liquid-enhanced laser osteotomy.

Available in PDF, EPUB and Kindle. Book excerpt: An optical feedback system for controlled precise tissue ablation is discussed. Our setup includes an ultrashort pulse laser (USPL), and a diagnostic system using analysis of either tissue fluorescence or plasma emission luminescence. Current research is focused on discriminating hard and soft tissues such as bone and spinal cord during surgery using either technique. Our experimental observations exhibit considerable spectroscopic contrast between hard and soft tissue, and both techniques offer promise for a practical diagnostic system.

Download or read book Laser Beam Shaping for Surgery and Microbiopsy written by Jason Brett King and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers are increasingly being used in surgery in a wide range of medical specialties due to their advantages over alternative surgical tools including precise material removal, limited bleeding due to coagulation around the incision site, and delivery through optical fibers enabling use in body cavities and for minimally invasive surgeries. Advancements in laser technology including new laser wavelengths and higher power continue to improve the performance and implementation of surgical lasers. Temporal beam shaping, or pulse modulation, has been implemented into clinical laser systems to increase efficiency of urological surgeries, leading to faster, safer procedures. However, the precise mechanisms of temporally shaped laser pulses on ablation are not fully understood. The effects of spatial beam shaping on laser tissue ablation have not previously been explored. Understanding the impact of temporal and spatial laser beam on laser ablation will improve the performance and increase the applications of laser surgery. In this dissertation a Ho:YAG laser was temporally and spatially altered and the effects on tissue ablation were explored. The first portion of this dissertation focuses implications of beam shaping on laser ablation efficiency. First, mechanisms of laser ablation with temporal pulse modulation are explored. We explore the mechanisms of pulse modulated ablation including experiments on phantoms and native kidney stones. We discovered that increased ablation efficiency by pulse modulation is composition dependent. Next, increased ablation efficiency by altering laser spatial shape is explored. We discovered that shaping the laser beam into an annular shape led to an increase ablation efficiency is both hard and soft tissues. The second portion of this dissertation focuses on application of spatially shaped laser ablation for laser microbiopsy. A novel method for harvesting sub-microliter (

Book excerpt: The second edition maintains the standard of excellence established in the first edition, while adjusting the content to reflect changes in tissue optics and medical applications since 1995. The material concerning light propagation now contains new chapters devoted to electromagnetic theory for coherent light. The material concerning thermal laser-tissue interactions contains a new chapter on pulse ablation of tissue. The medical applications section now includes several new chapters on Optical Coherent Tomography, acoustic imaging, molecular imaging, forensic optics and nerve stimulation. A detailed overview is provided of the optical and thermal response of tissue to laser irradiation along with diagnostic and therapeutic examples including fiber optics. Sufficient theory is included in the book so that it is suitable for a one or two semester graduate or for senior elective courses. Material covered includes (1) light propagation and diagnostic application; (2) the thermal response of tissue and therapeutic application; (3) denaturation; and (4) ablation. The theory and applications provide researchers with sufficient detail that this volume will become the primary reference for laser-tissue interactions and medical applications.
