RT Conference Proceedings T1 Parkinsons Disease Detection by using Isosurfaces with Convolutional Neural Networks A1 Ortiz-García, Andrés K1 Parkinson, Enfermedad de K1 Inteligencia artificial K1 Congresos y conferencias AB Computer aided diagnosis systems based on brain imaging are an important toolto assist in the diagnosis of Parkinson’s disease. The ultimate goal would be detec-tion by automatic recognizing of patterns that characterize the disease. In recenttimes Convolutional Neural Networks (CNN) have proved to be amazingly usefulfor that task. The drawback, however, is that 3D brain images contains a hugeamount of information that leads to complex CNN architectures. When thesearchitectures become too complex, classification performances often degrades be-cause the limitations of the training algorithm and overfitting. Thus, this paperproposes the use of isosurfaces as a way to reduce such amount of data whilekeeping the most relevant information. These isosurfaces are then used to im-plement a classification system which uses two of the most well-known CNNarchitectures to classify DaTScan images with an averageaccuracy of 95.1% and AUC=97%, obtaining comparable (slightly better) valuesto those obtained for most of the recently proposed systems. It can be concludedtherefore that the computation of isosurfaces reduces the complexity of the inputssignificantly, resulting in high classification accuracies with reduced computa-tional burden.
