An ultrasound probe configuration method, comprising: a dead zone of an ultrasound probe at a preset detecting depth is obtained (S11)； the ultrasound probe is placed in a three-dimensional magnetic field, and a first image obtained when the ultrasound probe scans air and a second image obtained when an acoustic lens of the ultrasound probe is in contact with a top end of a free transducer coated in a couplant are acquired (S12)； on the basis of color difference ratios, a first region and a second region having the longest continuous color differences on corresponding arcs are respectively selected, and median coordinates of the first region and the second region are calculated (S15)； on the basis of the median coordinates of the first region and the second region and the dead zone, two-dimensional coordinates of the top end of the free transducer in the second image are calculated and converted to three-dimensional coordinates to be measured, and on the basis of the three-dimensional coordinates to be measured and actual three-dimensional coordinates of the free transducer receiving the magnetic field, a ternary equation system is established, and a correction value for the ultrasound probe in the magnetic field is calculated. By means of the present method, measurement error is effectively reduced, and three-dimensional localization accuracy is improved.L'invention concerne un procédé de configuration d'une sonde ultrasonore, comprenant les étapes suivantes : une zone morte d'une sonde ultrasonore à une profondeur de détection prédéfinie est obtenue (S11) ； la sonde ultrasonore est placée dans un champ magnétique tridimensionnel et une première image obtenue lorsque la sonde ultrasonore balaye l'air et une deuxième image obtenue lorsqu'une lentille acoustique de la sonde ultrasonore est en contact avec une extrémité supérieure d'un transducteur libre revêtu dans un couplant sont acquises (S12) ； sur la base de rapports de différence de couleur, une première région
