Abstract
Method and apparatus for ultrasonically imaging objects of interest. The apparatus includes an elongate source of coherent acoustic waves which are brought to a line focus and propagated in an object of interest. The acoustic waves are detected by an elongate linear array of substantially point receivers which are located parallel to the elongate source and substantially at the line focus. The elongate source and the linear receiver array are translated together relative to the object of interest so that an area is swept out across the object of interest. The amplitude and the phase of the acoustic waves scattered by the object of interest are detected by the receiver array, digitized and back wave reconstructed to yield a digital image of the object of interest.
