Recognition of Tomographic Images in the Diagnosis of Stroke.

In this paper, a method for automatic recognition of acute stroke model using non-contrast computed tomography brain images is presented. The complexity of the task lies in the fact that the dataset consists of a very small number of images. To solve the problem, we used the traditional computer vision methods and a convolutional neural network consisting of a segmentator and classifier. To increase the dataset, augmentations and sub images were used. Experiments with real CT images using validation and test samples showed that even on an extremely small dataset it is possible to train a model that will successfully cope with the classification and segmentation of images. We also proposed a way to increase the interpretability of the model.
