Biologic System Evaluation with Ultrasound (eBook, PDF)

• Format: PDF

Produktbeschreibung

Biologic System Evaluation with Ultrasound is a reference book for engineers in the field of ultrasonics and is intended to inform those unfamiliar with current methods of ultrasonic analysis. Explaining the mathematical and physical principles of ultrasound imaging of living tissue with effective precision, the book encompasses the following topics: relationships between the biological and scattering hierarchies; graphic description of scattering; class 1,2,3,4 scattering and their association with the biological hierarchy; instruments used for biologic system evaluation; computed tomographic methods of imaging. The authors have provided an effective explanation of the ultrasound scattering of image and image acquisition that will benefit engineers, physicists, and radiologists alike.
