We employ a strategy of region-based classification within multiple segmentation hierarchies which is able to efficiently find target structures in a large set of possible segmentations. Furthermore, we present a novel set of border features, effectively capturing the border appearance under the noisy and diffuse conditions inherent to ultrasound images. Tested on 802 image series, our detection algorithm reaches a sensitivity/specificity of 84.2%/86.4%.enconference paper
