摘要： A system and computer-implemented method are provided for annotation of image data. A user is enabled to iteratively annotate the image data. An iteration of said iterative annotation comprises generating labels for a current image data part based on user-verified labels of a previous image data part, and enabling the user to verify and correct said generated labels to obtain user-verified labels for the current image data part. The labels for the current image data part are generated by combining respective outputs of a label propagation algorithm and a machine-learned classifier trained on user- verified labels and image data and applied to image data of the current image data part. The machine-learned classifier is retrained using the user-verified labels and the image data of the current image data part to obtain a retrained machine-learned classifier.

摘要： A system (100) includes a computing system (118) with a processor (120) and a computer readable storage medium (122) with computer readable instructions (124) including a localizer (126) with a re-ranker (204). The processor is configured to execute the re-ranker instructions, which causes the re-ranker to receive a plurality of ranked or scored candidate matches, wherein a ranked or scored candidate match includes a set of points of a shape model, and rank the ranked or scored candidate matches based on a predetermined set of features. The shape model represents an anatomical structure of interest.
