Publication number: 20150206300Abstract: A method is proposed for processing a CT brain scan to identify hematoma and extract data quantifying it. The method uses anatomical, pathological and imaging knowledge comprising (i) distribution data obtained from population studies and characterizing typical intensity distributions of one or more different types of material present in brains, one of the types of material being hematoma, (ii) at least one spatial template describing the spatial layout of a brain. Based on these, the method defines a respective volume of interest for each of a number of ventricles, and extracts data characterizing hematoma in the volume(s) of interest, which need not be hematoma within the ventricles. The distribution data describes typical intensity distributions of hematoma (clots), grey matter (GM), white matter (WM) and cerebrospinal fluid (CSF), and may be in Hounsfield Units (HU).Type: ApplicationFiled: January 21, 2014Publication date: July 23, 2015Inventors: Wieslaw Lucjan NOWINSKI, Varsha GUPTA

Patent number: 8831328Abstract: A method is proposed for segmenting a brain image into a CSF region, a WM region and a GM region. An upper limit for the intensity values of a CSF region in the image is estimated such that the points of the image having an intensity less than this upper limit include a subset of the points which form a spatially connected group and which have a peaked intensity distribution. In other words, the invention exploits both the expected spatial distribution and expected intensity distribution of the CSF region. This makes it possible for the method to provide reliable discrimination of the CSF region even in CT images with poor image quality. Various methods are proposed for using the upper limit, and for improving the segmentation accuracy.Type: GrantFiled: June 17, 2010Date of Patent: September 9, 2014Assignee: Agency for Science, Technology and ResearchInventors: Varsha Gupta, Wieslaw L.
