Instantaneous and Continuous Pictures Obtained by a New Two-Dimensional Scan Technique with a Stationary Transducer
In ultrasonic diagnosis and particularly in the investigation of the brain, the one- dimensional ultrasound pulse echo method (A-scan) has proved to be an important aid. The results thus obtained are, however, very limited and the echogram is often difficult to interpret. Generally, however, one is satisfied with the determination of an eventual shift of the midline. Therefore it is of great importance to try to produce two-dimensional pictures, because these could provide more complete and more reliable information.
