Abstract
A B-scan ultrasound probe imaging system including an array of annular transducers is described in which dynamic focussing is provided by coherent demodulation of the echo signals generated in the transducers. As the range from which echoes are being received increases, coherent demodulation is maintained. The system provides improved lateral resolution over a greatly extended useful range.
