Method for adjustment of the Doppler angle in echography

摘要

The invention relates to adjustment of the Doppler angle to a value close to the optimum Doppler angle DAopt, typically amounting to 60°, between the direction of an echographic excitation and the axis of a blood vessel in an echographic image, based on prior designation of an initial point in the vessel. The method according to the invention includes the following steps: a first measurement of the Doppler angle DA1 in a first, predetermined excitation direction; comparison of DA1 with DAopt and formation of $$ \text{Δθ = | DAopt - DA1 |}$$ ; correction of the direction of the echographic excitation by the value Δθ in order to shift it to a second direction.;Application: Analysis of images obtained by ultrasonic echography.
