Chapter 9: Glossary
This glossary includes an alphanumeric listing of all system symbols and system terms.
A “See” reference in the glossary refers you to the accepted SonoSite term. For example: rather than
probe or scanhead, transducer is the accepted SonoSite term for this product.
A “See also” reference in the glossary refers you to a term that is related to this term, or provides
more information about this term. For example: 2D, CPD, and DCPD imaging are the system
imaging modes; they are cross-referenced in this glossary to provide related information about
system imaging.
