LA WRENCE G. RAISZ, MD Division of Endocrinology and Metabolism, University of Connecticut Health Center. Farmington. CT The rapid transfer of new knowledge concerning the pathogenesis, diagnosis, preven tion, and treatment of disease into clinical practice has always been a major challenge in medicine. This challenge is particularly difficult to meet in osteoporosis, not only because has been so much new knowledge generated in recent years, but also because this there disorder has not caught the attention of many practicing physicians. The goal of this volume is to help primary care physicians develop a better understanding of osteoporosis and a more effective approach to diagnosis, prevention, and treatment. As primary care physicians become more and more responsible for the maintenance of health and the prevention of disease, osteoporosis must become one of their important concerns. The magnitude of the problem of osteoporosis has been widely publicized. Within the next 30 years, the cost of hip fractures alone is expected to exceed $40 billion a year in the United States and will be a major cause ofincreased mortality. In addition, vertebral crush fractures will cripple more and more of our elderly population, both men and women. This enormous toll is not inevitable. Current methods of identifying individuals at risk and applying preventive programs could reduce the incidence offractures by 50% or more. This should be the minimum goal of clinicians.

Biophysical Bone Behaviour: Principles and Applications is the culmination of efforts to relate the biophysical phenomena in bone to bone growth and electrical behavior. Behari develops a bridge between physics and biology of bone leading to its clinical applications, primarily electro stimulations in fracture healing and osteoporosis. The book is based upon authors own research work and his review articles in the area, and updated with the latest research results. The first book dedicated to biophysical bone behavior Develops the relationship between the biophysics and biology of bone into an integral unit Spans basic biophysical studies and clinical applications Links the various topics together to give readers a holistic understanding of the area Presents all major research findings about bone and biophysics Readers can access the full list of references at the companion website: www.wiley.com/go/behari

Project Report from the year 2018 in the subject Medicine - Biomedical Engineering, grade: 1.2, Egerton University, language: English, abstract: Medical imaging technology plays an important role of creating internal images of the human body for clinical or medical purposes. Historically, this technology was born in November 1895 when Wilhelm Roentgen discovered electromagnetic radiation (x-ray) (Levine, 2010). Medical imaging technique can be defined as a technique which each modality could provide unique details of the human body function. The discovery of x-ray was a motivation reason for others to improve various technologies in medical imaging over the past years such as computed tomography (CT), ultrasound and magnetic resonance imaging (MRI). Ultrasound is one of the medical imaging technologies that are known as sound waves with a frequency above 20 KHz that excess the human hearing range using non-ionizing radiation. Ultrasound is a diagnostic modality technique that has been in clinical use over the past 40 years when Theodore Dussik and his brother Friederich in 1940s attempted to diagnose brain tumours using ultrasound waves, although their incredible work achieved success in 1970s. The aim of this study is to test the hypothesis that the minimum ultrasound transit time above noise (derived from the transit time spectrum) through cancellous bone may predict the velocity measurement. Therefore, deconvolution method has been used to predict ultrasound transit time through cancellous bone and then compare it to the reported transit time from clinical ultrasound bone densitometer (CUBA).

Quantitative ultrasound (QUS) of bone is a relatively recent research field. The research community is steadily growing, with interdisciplinary branches in acoustics, medical imaging, biomechanics, biomedical engineering, applied mathematics, bone biology and clinical sciences, resulting in significant achievements in new ultrasound technologies to measure bone, as well as models to elucidate the interaction and the propagation of ultrasonic wave in complex bone structures. Hundreds of articles published in specialists journals are accessible from the Web and from electronic libraries. However, no compilation and synthesis of the most recent and significant research exist. The only book on QUS of bone has been published in 1999 at a time when the propagation mechanisms of ultrasound in bone were still largely unknown and the technology was immature. The research community has now reached a critical size, special sessions are organized in major international meetings (e.g., at the World Congress of Biomechanics, the annual meetings of the Acoustical Society of America, International Bone Densitometry Workshop, etc...). Consequently, the time has come for a completely up to date, comprehensive review of the topic. The book will offer the most recent experimental results and theoretical concepts developed so far and is intended for researchers, graduate or undergraduate students, engineers, and clinicians who are involved in the field. The central part of the book covers the physics of ultrasound propagation in bone. Our goal is to give the reader an extensive view of the mathematical and numerical models as an aid to understand the QUS potential and the types of variables that can be determined by QUS in order to characterize bone strength. The propagation of sound in bone is still subject of intensive research. Different models have been proposed (for example, the Biot theory of poroelasticity and the theory of scattering have been used to describe wave propagation in cancellous bone, whereas propagation in cortical bone falls in the scope of guided waves theories). An extensive review of the models has not been published so far. We intend in this book to present in details the models that are used to solve the direct problem and strategies that are currently developed to address the inverse problem. This will include analytical theories and numerical approaches that have grown exponentially in recent years. Most recent experimental findings and technological developments will also be comprehensively reviewed.

Medical applications of ultrasound range from therapy, foetal monitoring, diagnostic imaging and blood flow measurement, to surgery and lithotripsy. Ever since the earliest developments of medical ultrasound there has been an interest in the measurement and characterisation of the ultrasonic fields generated in these applications, either for assessment of performance of equipment or for safety. Until recently, procedures for acoustic output measurements were ill-defined, but standards are now being developed internationally by the International Electrotechnical Commission (1EC) and reliable commercial measuring equipment is becoming more widely available. The aim of this book is to introduce acoustic output measurement techniques and to provide an insight into the measurement methods. The material presented is based on a course originally run during November 1989 at the National Physical Laboratory. In addition to the lectures, the course consisted of a series of practicals to allow participants to gain experience of making measurements. Teddington, UK Roy C.
