Abstract

High-frequency ultrasound imaging can be performed with greater quality and suppressed grating lobes by using methods and systems for effectively reducing the temporal length of transmit grating lobe signals in received ultrasound echoes. Systems and methods are provided for improved high-frequency ultrasound imaging. In various aspects, the method of shortening the time domain of grating lobe signals comprises splitting an array of N transmit elements into K sub-apertures. In further aspects, the grating lobes are suppressed by performing signal processing of the shortened grating lobe signals. In certain aspects, the signal processing method comprises weighting the samples by a calculated phase coherence factor.
