A Non-Invasive Method for Two Dimensional Instantaneous Observation of Moving Cardiac Structures

Chapter

Summary

In this chapter an ultrasonic scanner with twenty adjacent elements is described. The system has been designed to evaluate a non-invasive technique for visualizing moving cross-sections of the heart, particularly the walls of the ventricle. Fast electronic switching from one element to another and appropriate display of the echoes results in the instantaneous display of a moving structure. In vitro measurements are discussed. In vivo measurements are illustrated in a case of severe mitral stenosis.
