Abstract
- The size of the ultrasonic beam and beam dispersion severely limit resolution by two-dimensional scanning systems. Resolution and tissue penetration are improved by using a highly focused, ultrasonic transducer array in conjunction with an electronic timing system for the selection of particular echo information.
