(57) ABSTRACT A method for automatic detection of obstructions in vascula ture in an
anatomical region is presented. The method includes partitioning the anatomical region into
a plurality of Sub-regions based at least in part on anatomical knowledge. Further, the
method includes adaptively computing a thresh old intensity value corresponding to each of
the plurality of Sub-regions. Additionally, the method includes extracting the vasculature in
each of the plurality of Sub-regions based on the corresponding computed threshold …
