Abstract (en)

This paper presents the recognition of ischemic stroke region of human head. Such method consists of six stages: pre-processing of computed tomograms, segmentation of ischemic stroke, computing of the centre of a stroke region, ray tracing, smoothing of determined stroke contour and expansion of it. The comparison analysis of automatically recognized stroke regions with regions, marked by four radiologists in 300 slices, showed mean value of stroke recognition which was bigger than minimal congruity factor between two radiologists.
