Abstract:
An imaging system comprising:a transducer array including a multiplicity of transducer elements for transmitting wave energy in response to electrical activation and transducing returned wave energy into electrical signals;a transmitter coupled to said transducer array and programmed to activate a plurality of said transducer elements to transmit wave energy focused at first and second focal points during first and second transmit events respectively;a receiver programmed to respectively form first and second receive signals from electrical signals supplied from said plurality of transducer elements subsequent to said first and second transmit events respectively;a segment processor for applying a weighting function to portions of said first and second receive signals returned from range points along a range segment lying between said first and second focal points to form first and second weighted receive signals, and then for combining said first and second weighted receive signals to form a combined receive signal; anda subsystem for displaying an image having an image portion which is a function of at least said combined receive signal.
