摘要:
A method and related system for improving resolution and frame rate of ultrasound images that includes specifying individual element transmit characteristics for each transmit beam in a set of transmit beams; determining various attributes of the transmit beams at field points in the field of view; using one or more of the attributes to determine if received ultrasound echo signals contributed by each transmit beam are qualified for use in image formation, and if so, how the signal should be processed; storing the determined information for each field point for repeated use with each new image frame; using the stored information to select and process subsequent received echo signals for each field point to produce an image parameter at the field point for each qualified echo signal; and combining multiple image parameters from overlapping transmit beams for a field point to produce a final image parameter that constitutes the field point value for the image frame.
