Abstract

Methods, systems, and apparatuses are disclosed for ultrasound imaging comprising Time Delay Spectrometry. A frequency swept signal can be transmitted through a medium, such as human tissue. The signal can be a low-voltage signal (e.g., 0 volts to 5 volts peak-to-peak) transmitted for long duration (e.g., 20 milliseconds) at various frequencies. As the signal propagates through the medium it can be reflected and delayed. A delay associated with the signal the can cause a change in the associated frequencies. The signal can be filtered to retain only frequencies in an audio frequency range. The signal can be beamformed and processed to produce an image.
