Abstract:
A system for imaging biological tissues, comprising:an ultrasound transducer array comprising a multiplicity of transducer elements;a transmit beamformer for pulsing said transducer array to transmit ultrasound beams in a scan plane;a receive beamformer for forming receive beams of acoustic data derived from echo signals detected by the transducer array subsequent to said transmissions;a signal processing chain for converting said acoustic data into an image frame of power Doppler imaging data;a video processor for color mapping said power Doppler imaging data in accordance with a current color mapping function having upper and lower knee points;an operator interface for selecting a change in the position of at least one of said upper and lower knee points;a computer programmed to construct a new color mapping function as a function of said selected change in position and load said new color mapping function into said video processor; anda display device for displaying an image representing a color-mapped image frame of power Doppler imaging data.
