Abstract
A presente invenção refere-se a um método para detectar mudança no grau de desvio de linha média no cérebro de um paciente. Enquanto o paciente permanece posicionado dentro do dispositivo de geração de imagem por ressonância magnética de campo baixo, adquirir os primeiros dados de imagem de ressonância magnética (MR) e os segundos dados de imagem de MR do cérebro do paciente; fornecer os primeiro e segundo dados de MR como entrada para um classificador estatístico treinado para obter as primeiras e segundas saídas correspondentes, identificar, a partir da primeira saída, pelo menos uma localização inicial de pelo menos um marco associado a pelo menos uma estrutura de linha média do cérebro do paciente; identificar, a partir da segunda saída, pelo menos uma localização atualizada do pelo menos um marco; e determinar um grau de mudança no desvio de linha média utilizando a pelo menos uma localização inicial do pelo menos um marco e a pelo menos uma localização atualizada do pelo menos um marco.
