Available in PDF, EPUB and Kindle. Book excerpt: Thermal ablation is a minimally-invasive procedure that is used as an alternative to surgical resection in treating early-stage solid tumors. Due to its percutaneous route of administration, thermal ablations have been shown to be associated with less bleeding, fewer complications and quicker recovery compared to surgery. While radiofrequency ablation (RFA) is currently the most common heating modality used for ablation, microwave ablations have rapidly gained traction in academic centers in recent years due to its improved heating physics. Microwave offers substantial benefits over radiofrequency ablation through faster heat generation, leading to larger and more homogenous ablation zones in highly-perfused tissue. These qualities can lead to better margins during tumor ablation and a smaller chance for tumor recurrence. However, controlling the high power and temperatures associated with microwave has remained a formidable barrier toward widespread clinical adoption. The tools used in microwave ablation, especially the antenna itself, require modifications in order to decrease shaft heating. The physics of microwave heating, which now incorporate water vaporization, needs to be accounted for in the tissue heating process. Lastly, the role of hotter ablation zones in thrombosing larger blood vessels is becoming a growing concern for physicians. This thesis aims to further our understanding of these issues.

Download or read book Performance Driven Surrogate Modeling of High Frequency Structures written by Slawomir Koziel and published by Springer Nature. This book was released on 2020-02-19 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses surrogate modeling of high-frequency structures including antenna and microwave components. The focus is on constrained or performance-driven surrogates. The presented techniques aim at addressing the limitations of conventional modeling methods, pertinent to the issues of dimensionality and parameter ranges that need to be covered by the surrogate to ensure its design utility. Within performance-driven methodologies, mitigation of these problems is achieved through appropriate confinement of the model domain, focused on the regions promising from the point of view of the relevant design objectives. This enables the construction of reliable surrogates at a fraction of cost required by conventional methods, and to accomplish the modeling tasks where other techniques routinely fail. The book provides a broad selection of specific frameworks, extensively illustrated using examples of real-world microwave and antenna structures along with numerous design examples. Furthermore, the book contains introductory material on data-driven and physics-based surrogates. The book will be useful for the readers working in the area of high-frequency electronics, including microwave engineering, antenna design, microwave photonics, magnetism, especially those that utilize electromagnetic (EM) simulation models in their daily routines. Covers performance-driven and constrained modeling methods, not available in other books to date; Discusses of a wide range of practical case studies including a variety of microwave and antenna structures; Includes design applications of the presented modeling frameworks, including single- and multi-objective parametric optimization.
Download or read book Radiofrequency Ablation for Small Hepatocellular Carcinoma written by Minshan Chen and published by Springer. This book was released on 2015-11-26 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive guide to the treatment of small hepatocellular carcinoma (sHCC) using a minimally invasive technique: radiofrequency ablation (RFA). RFA has emerged as a new treatment modality and become the main modality of locoregional therapy. Extensive clinical research indicates that RFA is as effective as surgical resection for sHCC, and it has the advantage of being less invasive. However, the outcomes after RFA are largely dependent on the operators’ experience- known as the “learning curve”. This book presents the characteristics of sHCC and discusses why sHCC is the best candidate for RFA. Then it introduces all the commercially available RFA systems, and their working principles, advantages, disadvantages and so on. It goes on to demonstrate how to perform RFA under the guidance of ultrasound, CT, laparoscopy, or during open operation. Finally, it discusses the radiologic assessment and follow‐up after RFA, as well as adjuvant therapies and clinical trials on RFA. The authors are experts from the fields of pathology, radiology, surgery, and gastroenterology, as well as manufacturers. With this book, readers gain have a clear idea of when and how to do RFA. It aims to standardize and generalize the procedure of RFA, which will be very helpful in improving the outcome of RFA for sHCC.

Download or read book Irreversible Electroporation written by Boris Rubinsky and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-thermal irreversible electroporation is a new minimally invasive surgical p- cedure with unique molecular selectivity attributes – in fact it may be considered the first clinical molecular surgery procedure. Non-thermal irreversible electro- ration is a molecular selective mode of cell ablation that employs brief electrical fields to produce nanoscale defects in the cell membrane, which can lead to cell death, without an effect on any of the other tissue molecules. The electrical fields can be produced through contact by insertion of electrode needles around the undesirable tissue and non-invasively by electromagnetic induction. This new - dition to the medical armamentarium requires the active involvement and is of interest to clinical physicians, medical researchers, mechanical engineers, che- cal engineers, electrical engineers, instrumentation designers, medical companies and many other fields and disciplines that were never exposed in their training to irreversible electroporation or to a similar concept. This edited book is designed to be a comprehensive introduction to the field of irreversible electroporation to those that were not exposed or trained in the field before and can also serve as a reference manual. Irreversible electroporation is broad and interdisciplinary. Therefore, we have made an attempt to cover every one of the various aspects of the field from an introductory basic level to state of the art.
Download or read book Tumor Ablation written by Eric van Sonnenberg and published by Springer Science & Business Media. This book was released on 2008-09-08 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an enormous sense of excitement in the communities of cancer research and cancer care as we move into the middle third of the ?rst decade of the 21st century. For the ?rst time,there is a true sense of c- ?dence that the tools provided by the human genome project will enable cancer researchers to crack the code of genomic abnormalities that allow tumor cells to live within the body and provide highly speci?c, virtually non-toxic therapies for the eradication,or at least ?rm control of human cancers. There is also good reason to hope that these same lines of inquiry will yield better tests for screening, early detection, and prev- tion of progression beyond curability. While these developments provide a legitimate basis for much op- mism, many patients will continue to develop cancers and suffer from their debilitating effects, even as research moves ahead. For these in- viduals, it is imperative that the cancer ?eld make the best possible use of the tools available to provide present day cancer patients with the best chances for cure, effective palliation, or, at the very least, relief from symptoms caused by acute intercurrent complications of cancer. A modality that has emerged as a very useful approach to at least some of these goals is tumor ablation by the use of physical or physiochemical approaches.
