REFoCUS (Retrospective Encoding for Conventional Ultrasound Sequences) allows us to frame multi-pulse transmission imaging as a linear system that can be decoded to perform synthetic aperture imaging.

Conventional imaging approaches are based on geometry - focused beams, plane waves, diverging waves. Spatial encodings are rooted in information theory - Hadamard codes, for example. We are exploring ...

Traditional ultrasound imaging techniques often struggle ... achieving image quality comparable to traditional synthetic aperture imaging while maintaining a high frame rate[1].
