Beyond Imaging

When most of us hear the word ultrasound, we typically think ofdiagnostic imaging; especially in regard to its use in obstetrics. Ultrasound, however, can also be used for a wide variety oftherapeutic applications, which the author has chosen as thetheme of this book. The book begins with a primer on sound waves, which are followedwith some basics on imaging. Next are descriptions of the evolvingtechnology, with a specific emphasis on medical applications. Examples are given of the different procedures that are carriedout using sophisticated, non-invasive, image-guided devices. Eachprocedure is carefully explained with the help of many detailedillustrations. Examples of these include the destruction of tumorsdeep within the body using highly focused ultrasound beams. Especially impressive are the treatments that are guided with realtimeMRI. One in particular is employed for opening barriers inthe brain to facilitate the delivery of a range of agents for treatingconditions such as Alzheimer s disease. For almost thirty years, Victor Frenkel has worked as a teacher,mentor, and research scientist at medical schools, engineeringdepartments, and government institutions. Along the way he madehis own contributions in the field of therapeutic ultrasound. Theseinclude the development of novel treatment protocols, and alsodesigning and building the devices used to carry them out. Toldwith easy-to-follow language, including key historical and culturalperspectives, this book is meant for anyone who loves cutting edgetechnology, especially pertaining to medical treatments.
