Claim 7:
8. A method of ultrasound imaging, the method comprising:
generating ultra-wideband frequency modulated (UWFM) ultrasound signals that have a time-bandwidth product (TBP) that is larger than 1,
transmitting the generated ultrasound signals and receiving ultrasound signals via at least one linear array of micromachined ultrasound transducers that are coupled to a patient body, wherein the transmitting and receiving are carried out sequentially through the transducers to the body by switching the transducers one at a time according to a predefined pattern that simulates a moving transmitter and a moving receiver having a virtual velocity which yields a Doppler effect,
analyzing the received ultrasound signals with respect to the transmitted ultrasound signals and the predefined transmission pattern,
deriving a tissue response by comparing the received ultrasound signal to the transmitted ultrasound signal from each of the transducers, and
generating, from the derived tissue response, a far-field ultrasound image of a region of interest (ROI) in the patient body, as a Range-Doppler map of the ROI.
