Digital echocardiography has evolved rapidly during the last
decade, and the all-digital echocardiographic laboratory has just
reached the threshold of reality. This review article explains what
this transition means for the modern medical practice and concisely
presents what a digital echocardiogram is, the technical aspects of
digital image acquisition and processing, and the advantages and
limitations of digital echocardiography vs analog echocardiography.
This review should serve as a useful source of information for the
general cardiologist not working closely with digital echocardiography,
as well as a resource for the noncardiologist.
