Abstract

resumo sistema de ressonância magnética (rm) para a manutenção do alinhamento geométrico de varreduras de diagnóstico durante o exame de um paciente, método de ressonância magnética (rm) para a manutenção do alinhamento geométrico de varreduras de diagnóstico durante o exame de um paciente, e sistema de ressonância magnética (rm) para a manutenção do alinhamento geométrico de varreduras de diagnóstico de um paciente um sistema de ressonância magnética (rm) (10) e um método (100) mantêm o alinhamento geométrico de varreduras de diagnóstico durante o exame de um paciente (12). pelo menos um processador (40) é programado para, em resposta ao reposicionamento do paciente (12) durante o exame, realizar uma varredura de pesquisa atualizada do paciente (12). uma varredura concluída durante o exame é selecionada como uma varredura modelo. um mapa de transformação entre a varredura modelo e a varredura de pesquisa atualizada é determinado com a utilização de um algoritmo de registro, e o mapa de transformação é aplicado à geometria de varredura de uma varredura de diagnóstico restante do exame. um plano de verificação para a varredura de diagnóstico restante é gerado com a utilização da geometria de varredura atualizada. a varredura de diagnóstico restante é realizada de acordo com o plano de varredura. 1/1
