Ultrasonic imaging method and image for doppler tissue parameters

摘要

An improved Doppler tissue imaging mode combines two Doppler image parameters developed as respective functions of receive signals acquired from a single firing event to generate a combined image parameter for display. In one example, the combined image parameter has a color hue that varies in a piecewise linear way with Doppler tissue velocity or Doppler tissue acceleration and a color value or intensity that varies linearly with Doppler tissue energy. Because the same firing events are used to develop both Doppler image parameters for a given region of tissue, high temporal and/or spatial resolution is made possible.
