1. A method for producing a composite interference-free ultrasound image when non-imaging ultrasound waves would otherwise interfere with ultrasound imaging, comprising the steps of: (a) providing a plurality of ultrasound image frames that were produced in the presence of non-imaging ultrasound waves; (b) automatically analyzing the plurality of ultrasound image frames to identify interference-free portions of the ultrasound image frames; and (c) automatically combining a plurality of interference-free portions to generate the composite interference-free ultrasound image.
