Claim Text:
1. A method for determining a property of a biological vessel based on an improved estimation of a waveform parameter, comprising: (i) receiving image data of the biological vessel; (ii) determining a centerline of the biological vessel based on the image data and generating a plurality of analysis planes that lie perpendicular to the centerline; (iii) generating time-based waveforms based on the analysis planes; (v) fitting surfaces to upslope regions of different subsets of the waveforms to derive local waveform parameters based on intersections of the surfaces with the upslope regions; and (v) determining a global waveform parameter based on the local waveform parameters; wherein the global waveform parameter is associated with the property of the biological vessel.
