Abstract
A rapid, non-invasive realtime modality for detecting differential backscatter in ultrasound is achieved using narrowband interrogating frequencies to maximize signal-to-noise ratio and to minimize location errors. Additional improvement in signal-to-noise ratio and separation of tissue populations are achieved by cyclically alternating through a fixed number of predetermined burst lengths and by employing multiple narrowband bursts of differing fundamental frequencies.
