ABSTRACT:
The invention relates to a medical imaging station including acquisition means ACQ for obtaining images IM exhibiting levels of gray, means DIS of displaying images IM, segmentation means SEG for segmenting at least one imaged object, said segmentation means SEG determining a so-called segmentation zone IMS delimiting the image object on the image, and means TR of extracting at least one path PAT within the segmentation IMS. The station according to the invention is such that the extraction means include means POS of positioning an initial point on the segmentation, means PROP of propagating an edge within the segmentation IMS from the initial point, means TES of testing the connectedness of the edge, means LAB of labeling portions of the edge, referred to as ramifications, when a non-connected edge is detected, means IDE of identifying final points PF of the propagation on the ramifications, path tracing means TRA for tracing a path PAT from final points PF and the initial point. Application: Medical imaging
