This book was released on 2005 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal ablation of benign prostatic hyperplasia (BPH) and prostate cancer is a minimally-invasive alternative to standard surgical prostate treatments. Although minimally invasive, many of the current prostate thermal ablation technologies lack the ability to precisely treat large prostate regions while avoiding sensitive surrounding structures. This Ph.D. dissertation describes the development and evaluation of directional transurethral ultrasound applicators capable of precise image-guided prostate ablation. MR compatible, transurethral ultrasound applicators were designed and fabricated using either planar, sectored tubular, or slightly focused curvilinear transducers. The applicator designs consisted of a linear array of separately powered transducers integrated onto a custom multi-lumen catheter, which could be rotated within an inflatable urethral cooling balloon. A computer-controlled, MR compatible motor system was developed to rotate the applicators during thermal procedures. Controlled image-guided ablation of prostate tissue was demonstrated in multiple in vivo canine experiments. An open bore interventional MR system allowed for direct access during the thermal procedures with concurrent MR temperature imaging. Single stationary sonications of the directive transurethral applicators ablated selective prostate regions (20-70°) out to prostate capsule. Larger ablation zones were then created by rotating the directive applicators in discrete angular steps. The depth of ablation at each angle was controlled by continuously regulating the applied power level and sonication duration with MR temperature feedback as guidance. An acoustic and biothermal model of transurethral ultrasound thermal therapies was also developed and verified in this work. Studies with the biothermal model demonstrated that all three applicator types could conformably ablate prostate tissue out to the prostate capsule boundary while avoiding thermal damage to rectal tissues. The curvilinear applicator proved the most selective applicator and the tubular applicator required the shortest treatment times and was the easiest to control. In summary, this work represents a major advance in image-guided prostate thermal therapy. There is proven potential for directive transurethral ultrasound applicators and the technologies developed herein can be easily modified to treat other intraluminal locations such as esophageal and rectal pathologies. With added development and verification, the biothermal model may provide a base for future thermal treatment planning systems.

Available in PDF, EPUB and Kindle. Book excerpt: The physical properties of ultrasound, particularly its highly directional beam behaviour, and its complex interactions with human tissues, have led to its becoming a vitally important tool in both investigative and interventional medicine, and one that still has much exciting potential. This new edition of a well-received book treats the phenomenon of ultrasound in the context of medical and biological applications, systematically discussing fundamental physical principles and concepts. Rather than focusing on earlier treatments, based largely on the simplifications of geometrical acoustics, this book examines concepts of wave acoustics, introducing them in the very first chapter. Practical implications of these concepts are explored, first the generation and nature of acoustic fields, and then their formal descriptions and measurement. Real tissues attenuate and scatter ultrasound in ways that have interesting relationships to their physical chemistry, and the book includes coverage of these topics. Physical Principles of Medical Ultrasonics also includes critical accounts and discussions of the wide variety of diagnostic and investigative applications of ultrasound that are now becoming available in medicine and biology. The book also encompasses the biophysics of ultrasound, its practical applications to therapeutic and surgical objectives, and its implications in questions of hazards to both patient and operator.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the International School of Radiation Damage and Protection at the "Ettore Majorana" Centre for Sci entific Culture in Erice, Italy, September 6-15, 1985. The sixth course of the School, entitled "Advances in Applications, Biological Effects, and Dosimetry of Ultrasound," provided an in-depth review of all facets of ultra sound interactions and their biological effects on living systems, allowing an assessment of the hazard potential of the various applications of ultra sound. Particular reference was made to possible health risks associated with medical ultrasound exposure since this use is by far the most prevalent. Since the initial application of ultrasound to submarine detection, medical diagnostic and therapeutic applications have become predominant over the past 20 years. The question of safety of this physical agent is an extremely important one. In many industrialized countries most pregnant women receive at least one diagnostic ultrasound examination before the birth of the child. Thus, potential hazards to the fetus are of prime concern. This problem has been aggravated by the fact that the medical diagnostic applications of ultrasound have far outpaced research efforts on biological effects. A further compounding factor of concern to clinicians and scientists has been the use of higher and higher intensities by the manufacturers of ultrasound equipment, particularly higher peak pulse intensities.
