Claim One:
1. A method of ultrasound reflective image reconstruction for waveforms generated within a medical ultrasound imaging device, comprising: (a) receiving a heterogeneous sound-speed model of a tissue region being imaged; (b) receiving ultrasonic waveform information in response to reflection data for the tissue region being imaged; and (c) reconstructing a reflection image using a split-step Fourier transform propagator configured for recursive inward continuation of ultrasonic wavefields in the frequency-space and frequency-wave number domains by: (i) applying a first phase-shift term to said ultrasonic waveform information in the frequency-wave number domain for propagation in a reference medium; and (ii) applying a second phase-shift term to said ultrasonic waveform information in the frequency-space domain to compensate for ultrasonic scattering effects of heterogeneities within said tissue region.
