Abstract
A three-dimensional imaging system for obtaining a three-dimensional image of an object being scanned ultrasonically comprises a source arrangement for sequentially transmitting ultrasonic energy toward the object in successive directions in a first scanning plane, followed by sequential transmission of ultrasonic energy toward the object in successive directions in successive scanning planes parallel to the first scanning plane, a detector arrangement for receiving reflected energy and converting the reflected energy to electrical signals, and a processor for processing the electrical signals to develop reconstructed image data of the object, the reconstructed image data comprising forward projections of the object into a left image plane and a right image plane to form left and right images, respectively, the left and right images forming a stereo pair for composite display by a display unit. In a further embodiment of the invention, the source arrangement sequentially transmits ultrasonic energy toward the object in successive directions in a first scanning plane, and repeats the sequential transmission of ultrasonic energy in successive scanning planes, the successive planes having increasing angular orientations with respect to the first scanning plane. Further features of the invention include the provision of various source-detector combinations and arrangements, as well as the simultaneous generation of ultrasonic beams having different frequencies in different respective directions during each given scanning cycle.
