1. A method for segmenting and measuring anatomical structures in fetal ultrasound images comprising the steps of: providing a digitized ultrasound image of a fetus comprising a plurality of intensities corresponding to a domain of points on a 3-dimensional grid; providing a plurality of classifiers trained to detect anatomical structures in said image of said fetus; and segmenting and measuring an anatomical structure using said image classifiers by applying said elliptical contour classifiers to said fetal ultrasound image, wherein a plurality of 2-dimensional contours characterizing said anatomical structure are detected.
