摘要
A method for detecting solid components in ground glass nodules (GGNs) in medical images, includes: performing an intensity-based segmentation on a segmented GGN to identify a high intensity region; and performing a shape analysis to determine whether the high intensity region is a solid component or a vessel, wherein the shape analysis comprises: computing a compactness of the high intensity region; and determining whether the high intensity region is a solid component or a vessel by using an area, a maximum distance on a distance transform map and the compactness of the region; or determining whether the high intensity region is a solid component or a vessel by scaling and normalizing the region and computing a compactness for the scaled and normalized region.
