Evolving Cellular Neural Networks for the Automated Segmentation of Multiple Sclerosis Lesions

  • Chapter
Variants of Evolutionary Algorithms for Real-World Applications

Abstract

This chapter presents an innovative approach for the segmentation of brain images that contain multiple sclerosis (MS) white matter lesions. Quantitative research of Magnetic Resonance Images (MRI), aimed at detecting and studying lesion load and tissue volumes, has turned out to be very useful for the re-evaluation of patients and clinical assessment of therapy. Until now, the standard procedure for this purpose has been the manual delineation of MS lesions, which makes the analysis a time-consuming process. The application presented in this work is a genetic algorithm (GA) that evolves a Cellular Neural Network (CNN) for pattern recognition. This network is capable to automatically segment the brain areas affected by lesions in MRI and also to immediately eliminate the parts of the brain that are not directly connected to the disease (like the skull, the optic nerve, etc.) in the segmentation process. In comparison to manual segmentations, the proposed method shows a very high level of reliability. It must also be reported that the relative algorithm is more accurate and it adapts to different conditions of the stimulus. Furthermore, it can create 3D images of the brain regions affected by MS, providing new perspectives of the diagnostic analysis of this disease. The work has practical applications in the medical field. Future industrial development of this work could lead to the embodiment of the algorithm directly into the MRI equipment, because CNNs can be implemented in hardware (via discrete off-the-shelf components) or fabricated as a Very Large Scale Integrated (VLSI) chip.
