Abstract

A method and device for three dimensional ultrasonic scanning of a patient is described by which an ultrasonic probe scans image planes oriented in a wedge or fan shaped volume. The probe is moved in an arc of travel about an apex which is below the scanning device and may be adjustably located within the probe or lower, such as between the ribs of the patient. The inventive method and device enable a significant volume of the heart to be scanned intercostally and viewed in a three dimensional image format.
