Abstract
An ultrasound imaging system may use a capacitive membrane or electrostrictive ultrasound transducer to realize isotropic volumetric imaging with bias-line element selection and a variety of aperture synthesis techniques. Two dimensional beam formation may be performed by using a beamformer to focus along one dimension, and then perform a second round of “off-line” or “retrospective” beam formation along the other direction.
