This book is the first in a groundbreaking series exploring the innovative realm of High Intensity Focused Ultrasound (HIFU) surgical treatments. It serves as an essential reference for students, scientists, engineers, and clinicians eager to understand and apply minimally invasive and non-invasive focused ultrasound therapy. This volume delves into the fundamentals of HIFU therapy, covering critical topics such as transducers, ultrasound tissue properties, and induced bioeffects. Key concepts include the principles of HIFU thermal ablation, the physical mechanisms behind it, and the critical issues for successful application. The book provides a comprehensive guide to ultrasound-guided HIFU treatment for benign gynecological diseases, detailing pretreatment preparation, step-by-step procedures, precautions, results, and potential complications. Readers will gain insights into the treatment of conditions such as uterine fibroids, adenomyosis, and abnormal placental attachment, among others. Gynecological surgeons, HIFU researchers, and surgeons interested in non-invasive surgery development will find this book invaluable. It offers a detailed exploration of HIFU applications in gynecology, many of which are seldom practiced or reported in the literature, making it a must-read for those at the forefront of medical innovation.
