The Human Epidermal Growth Factor Receptor 2 (HER2/neu) is a biomarker, recognized as a valuable prognostic and predictive factor for breast cancer. In approximately 20% of primary breast cancers, the HER2/neu protein is over-expressed. By recent clinical research, a treatment procedure, with corresponding monoclonal antibodies specifically designed to(More)
In this paper a decision making support system based on fuzzy logic is considered. The examined decision problem is related to the problem of recognition of histopathology images with respect to the degree of HER2/neu receptor overexpression. We used fuzzy decision trees, defined over different sets of image features, as separate image classifiers. Then,(More)
In this article, a method of histopathology image recognition, based on image similarity is presented. The image similarity is interpreted in terms of fuzzy rough sets. Approximations of fuzzy sets are used for investigation how close (in terms of fuzzy rough sets) is a considered histopathology image to a reference image information, which enables HER2(More)
In this article, the specification of a histopathology decision making support system, based on Pawlak’s information system concept and Mamdani type fuzzy control is presented. The proposed system supports the recognition process of HER-2/neu histopathology preparations through microscopy image information analysis. We used Pawlak’s information system to(More)
In this paper a decision making support system dedicated to histopathology image recognition is considered. The proposed system supports the classification process of histopathology preparations through microscopy image information analysis, with respect to the degree of HER2/neu receptor overexpression. The system combines the output information of(More)
During recent years a number of medical diagnosis support systems have been presented. Such systems are important from medical point of view, because they aid physicians in their daily work. Some of those systems, like Computed tomography support systems (CT) rely on image data analysis, making it an interesting research topic from pattern recognition point(More)
The human epidermal growth factor receptor 2 (HER-2/neu) is a biomarker, recognized as a valuable prognostic and predictive factor for breast cancer. In approximately 20% of primary breast cancers, the HER2/neu protein is over-expressed. The effect of this over-expression is an increase in receptor mediated intracellular signalling, directing the cancer(More)
Acute mesenteric ischemia secondary to arterial occlusion is a highly lethal condition, mandating early diagnosis and prompt therapy, to prevent, or at least to minimize, bowel infarction. Progress in understanding the pathophysiology of mesenteric ischaemia has led to novel methods of treatment, so that in some circumstances therapy may be purely medical.(More)
