The introduction of the prototype of an ultrasonic linear array scanner in 1971, confronted us with a type of diagnostic information which was different from conventional cardiac imaging techniques. With the use of ultrasound, cardiac structures were now displayed in a direct and positive manner rather than as shadows or negative impressions in contrast media as seen with X-ray and angiocardiographic techniques. Imaging in multiple new planes through the heart now became possible. These planes were difficult or impossible to visualize With other techniques. Therefore hardly any knowledge about the anatomic information in these images existed. The major aim of this thesis is to present the implementation into the clinical practice of cardiology of the linear array system which was developed at the Thoraxcenter in Rotterdam
