Abstract

An ultrasonic diagnostic imaging system and methods are described which produce tissue harmonic ultrasonic images from harmonic echo components of a transmitted fundamental frequency. Fundamental frequency waves are transmitted by an array transducer to focus at a focal depth. As the transmitted waves penetrate the body, the harmonic effect develops as the wave components begin to focus. The harmonic response from the tissue is detected and displayed, while clutter from the fundamental response is reduced by excluding fundamental frequencies. The technique is especially useful for imaging the endocardial tissue of the heart.
