Interventional Oncology is a fast-growing new field, as well as an emerging specialty. Many minimally-invasive, imaging-guided procedures seem set to replace more traditional open surgical techniques of treating solid tumors in a variety of organs. The aim of this book is to describe new interventional radiological methods in a succinct and practical form. Diagnostic radiological considerations relevant to the selection and follow-up of patients are also covered. The book begins with an overview of the basic principles of current interventional techniques, including thermal ablation, high intensity focused ultrasound, and embolization. Later chapters focus on tumors of the liver, kidney, lung, and bone, placing new interventional techniques in context by referring to the surgical and oncologic methods of treating the same conditions. With an emphasis on best practices, Interventional Oncology: A Practical Guide for the Interventional Radiologist will serve as a definitive guide to practicing physicians involved in this rapidly evolving field.
Laser bonding is a marking technique that uses lasers and other forms of radiant energy to bond an additive marking substance to a wide range of substrates. Invented in 1997, this patent protected technology delivers permanent marks on metals, glass and ceramic parts for a diverse range of industrial and manual applications, ranging from aerospace to the awards & engraving industries. It differs from the more widely known techniques of laser engraving and laser ablation in that it is an additive process, adding material to the substrate to form the marking instead of removing it as in those techniques. For metals, parts can be permanently marked with high contrast, high resolution marks for logos, bar-coding, identification and serialization purposes, without damage to the substrate. With glass and ceramics, complex surfaces can be decorated or marked and the traditional firing process replaced by a laser, with its permanent bond fired on in seconds. Laser bonding has been achieved by Nd:YAG, CO2 laser, Fiber laser and Diode-pumped solid-state laser and can be made by other forms of radiant energy. Laser bonding is often referred to as CerMark, CerMarked, or CerMarking
Authoritative and lavishly illustrated, this book is a valuable compendium of surgical techniques for the most complex oncologic problems in the head and neck patient. It distills the author's decades of experience in the surgical management of cases in which the excision of complex lesions is difficult and reconstruction is problematic. In the first half of the book, each chapter addresses cancer in a different region of the head and neck. Each chapter provides discussion of etiology, pathology, pathophysiology, and surgical anatomy, providing the necessary background for diagnostic evaluation, surgical treatment as well as nonsurgical treatment, including chemotherapy and radiation. Additional chapters cover such important topics as care for the pediatric patient, radiotherapy, restoration secondary to tumor ablation, and speech, voice, and swallowing implications following ablative procedures.Features:-Detailed descriptions that guide the clinician through each surgical procedure-Comprehensive discussion of management strategies that provides clinicians with a solid understanding of the available treatments and the possibilities and limitations of each-Nearly 1,000 high-quality illustrations, photographs, and radiographic images that demonstrate pathologic and surgical concepts in precise detail-Coverage of the latest techniques in skull base surgery and laryngeal surgery-Valuable discussion of nursing care, nutrition, and speech therapyAn essential resource for optimizing the care of patients with advanced cancer, this book is ideal for clinicians and residents in otolaryngology-head and neck surgery, facial plastic and reconstructive surgery, oral and maxillofacial surgery, oncology, and general surgery.
First implantations of Ba and Cs atoms into solid He by means of laser ablation were done in 1993 at MPQ (Max Planck Institut für Quantenoptik). Solid He is very well suited for high precision spin physics. The implanted atoms diffuse only very slowly out of the investigation region (few hours) in contrast to superfluid He (less than one second). Atoms in solid He are mainly lost due to dimer and cluster formation. A constant number of foreign atoms can be obtained by applying pulses from the same Nd:YAG laser used for the ablation process, thereby destroying the clusters. Longitudinal spin relaxation times of 1 second for Cs in solid He and magnetic resonance linewidths of 2,kHz (two orders of magnitude smaller than in superfluid He) were measured. The lines were broadened by residual magnetic fields and later, linewidths of only 20,Hz were obtained after reduction of magnetic field inhomogeneities. Doped solid He is such a complex and unique system that it has led to many interesting discoveries, some of them are discussed in detail in this work.
This dissertation, through a systematic investigation of the behavior of the gas-phase dynamics ofnanoparticles generated by laser ablation of solid target materials in background gasesand a study of the physical processes involved in gas-phase nanoparticle processing, explores the combination of laser and aerosol processes as a novel approach to make thinfilm materials with a level of microscopic organization similar to that found in nature.The integrated laser-aerosol method is very flexible and can be used in thesynthesis of a variety of materials. In this study it is applied to the deposition ofnanocomposite thin films comprising tetrahedral amorphous carbon (ta-C) withembedded metal nanoparticles. The controlled incorporation of metal nanoparticlesenables the modulation of the electrical conductivity of ta-C over four orders ofmagnitude without significantly or adversely affecting its mechanical properties.
