ABSTRACT
Vascular ultrasound combines various modalities to study blood vessels and blood flow (Fig. 1.1). Modern systems use B-mode and pulsed Doppler combined as the duplex scanner. This book will not attempt to explore all aspects of ultrasound physics as they are covered in dedicated texts listed at the end of the book as ‘Recommended reading’. However, vascular ultrasound cannot be understood without discussing basic principles.
