Physical Principles of Ultrasound
The use of ultrasound is fundamental to the practice of urology. In order for urologists to best use this technology on behalf of their patients, they must have a thorough understanding of the physical principles of ultrasound. Understanding how to tune the equipment and to manipulate the transducer to achieve the best-quality image is crucial to the effective use of ultrasound. The technical skills required to perform and interpret urologic ultrasound represent a combination of practical scanning ability and knowledge of the underlying disease processes of the organs being imaged. Urologists must understand how ultrasound affects biological tissues in order to use this modality safely and appropriately. When the physical principles of ultrasound are fully understood, urologists will recognize both the advantages and limitations of ultrasound.
