Detecção de ativação em ressonância nuclear magnética funcional do cérebro

Pedro Paulo de M. Oliveira JuniorMarcelo Gattass

Magnetic Resonance Image (MRI) is a useful non-invasive technique for medical diagnostic, yielding high quality images. In the last years, a technique based on MRI called functional MRI is growing in the medical community as a mean to map the sensorial and motor activities into the brain. This paper presents an image processing techniques to find the areas of brain that are activated in response to motion and the tactual areas using images collected with a 1,5 Tesla MRI Scanner. Results, also presented here, indicate the feasibility of using current MRI scanners to perform functional analysis.
