In this introductory chapter, a pedagogical overview on the technical foundations of ultrasound imaging will be provided to guide readers who are new to the biomedical ultrasound field. The intent here is to equip readers with fundamental principles that would serve well as background knowledge to understand the broad range of technical concepts covered in this book. Not only will the general physics of ultrasound and the key imaging considerations be outlined, engineering aspects such as system hardware will also be covered. In addition, commentary on the emerging trend toward high-frame-rate imaging will be included to highlight latest innovation thrusts in ultrasound imaging.
