1. A method for determining peak velocity of fluid flowing in a blood vessel, said method comprising:

  • (a) measuring a set of spatially proximate ultrasound images along said blood vessel, wherein said set of ultrasound images are measured with an ultrasound transducer, wherein each of said ultrasound images is of a planar cross-section of said blood vessel, and wherein each of said ultrasound images provides a Doppler-generated velocity map of said fluid in said planar cross-section;

    (b) determining an uncorrected peak velocity of said fluid, wherein said uncorrected peak velocity is located at or near one of said planar cross-sections;

    (c) identifying a high velocity center in each of a plurality of said ultrasound images;

    (d) calculating a Doppler angle based on said high velocity centers of said ultrasound images; and

    (e) correcting said peak velocity based on said calculated Doppler angle.
