Half of local, active outline for a blast pipe region detection in knee - ct - images

摘要

An exemplary method for detecting a structure in a three-dimensional (3 - d) computed tomography ("ct") - image of a knee is stated. An intensity before rank mask is (in the case of 910) created, on the basis of a two-dimensional (2 - d) cut of the ct - image. A nucleus point in the 2 - d - section which is received or estimates (in the case of 915). The nucleus point lies in a hoffa - cushions - region. A geometric priority mask is created, (in the case of 920) on the basis of the nucleus point. The intensity in front of rank mask and the geometric mask are combined (in the case of 925), in order to form a region of mask. A level - adjusted outline, (in the case of 930) from the 2 - d - section segmented. The step of the segmentation is forced by the region of mask.
