Abstract

EQUIPAMENTO MÉDICO, PRODUTO DE PROGRAMA DE COMPUTADOR E MÉTODO DE OPERAR UM EQUIPAMENTO MÉDICO. A invenção provê um equipamento médico (200, 400) compreendendo um sistema de aquisição de imagens por ressonância magnética (202) e um sistema de ultrassom focalizado de alta intensidade (222). Um processador (246) controla o equipamento médico. As instruções fazem com que o processador (100) controle o sistema de aquisição de imagens por ressonância magnética para adquirir os dados de ressonância magnética utilizando uma sequência de pulsos (254). A sequência de pulsos compreende uma sequência de pulsos de aquisição de imagem por força de radiação acústica (500, 600). A sequência de pulsos de aquisição de imagem por força de radiação acústica compreende um pulso de excitação (512) e um pulso de gradiente multidimensional (514) aplicado durante o pulso de excitação de radiofrequência para seletivamente excitar uma região de interesse (239) englobando uma zona alvo e pelo menos uma parte do eixo de feixe. As instruções fazem com que o processador controle (102) o sistema de ultrassom focalizado de alta intensidade para sonicar a zona alvo durante a sequência de pulsos de aquisição de imagem por força de radiação acústica e reconstruir (104) uma imagem por força de radiação (258) utilizando os dados de ressonância magnética.
