The work presented in this series of lectures covers a spectrum of ideas and techniques that are part of a technology for imaging — a technology that has been expanding and growing over the past several years. It was only a short while ago that ultrasonic imaging was confined to a few institutions and the instrumentation consisted of variations of the system made up of a sound beam in the form of a pencil-like probe that was scanned either by hand or with the aid of mechanical levers. Many images were recorded from a storage tube with two levels of brightness — black and white. Research workers and clinicians have developed a great skill in the use of these instruments and a vast amount of information has been recorded by a careful, systematic exploration and correlation with known features. One prime example of the technique has been described by Dr. F. Weill1 and his co-authors in Besancon, France.
