Producing pseudocolor images for diagnostic ultrasound imaging

摘要

A method for displaying the values of two parameter at a plurality of points in an image. The intensity of each pixel in the display is modulated in accordance with the value of the first parameter at corresponding points in the image. The hue of each pixel is modulated to a first color whenever the value of the second parameter at the corresponding point in the image is greater than a reference value and to a second color whenever the value of the second parameter is less than the reference value. The saturation at each pixel is modulated as a function of the absolute value of the deviation of the second parameter from the reference value at the corresponding point in the image. In a preferred embodiment, the first parameter corresponds to the amplitude of echoes in a diagnostic ultrasound image and the second parameter corresponds to the instantaneous frequency deviation of the echoes.
