  5. 4. A Computer Aided Detection System for Cerebral Microbleeds in Brain MRI

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Babak Ghafary Asl; [2012]
    Nyckelord :Brain MRI; cerebral microbleeds; classication; computer aided diagnosis.;

    Sammanfattning : Advances in MR technology have improved the potential for visualization of small lesions in brain images. This has resulted in the opportunity to detect cerebral microbleeds (CMBs), small hemorrhages in the brain that are known to be associated with risk of ischemic stroke and intracerebral bleeding.
