Patent ID: 8715191

Claim:
A method of processing and displaying received Doppler signals, the method comprising the steps of: obtaining, based on the received Doppler signals, a set of N power spectra corresponding to each of N times; and displaying of set of pixels with respect to an X axis and a Y axis so that the X coordinate of each pixel in the set corresponds to a time and the Y coordinate of each pixel in the set corresponds to a quantized power level, wherein an attribute of each pixel in the set is set to represent the highest velocity for the time-and-quantized-power-level combination that corresponds to the X and Y coordinates of each pixel in the set, and wherein, when the attribute of each pixel in the set is set, velocities that are lower than the highest velocity for the time-and-quantized-power-level combination that corresponds to the X and Y coordinates of each pixel are disregarded.
