Abstract

sistema de formação de imagem de diagnóstico ultrassônico. um sistema de formação de imagem de diagnóstico ultrassônico explora uma pluralidade de fatias planares em uma região volumétrica contendo tecido que foi objeto de perfusão por um agente de contraste. a pluralidade de fatias escaneadas são mutuamente paralelas. se seguindo à detecção dos dados de imagem das fatias, os dados de fatia são combinados projetando os dados na dimensão de elevação para produzir uma imagem de fatia combinada de perfil. a combinação pode ser por intermédio de uma detecção de intensidade média ou máxima ou processo de ponderação ou por raycasting na dimensão de elevação em um processo de interpretação volumétrica. a imagem de fatia combinada em elevação é processada para produzir uma medida qualitativa ou quantitativa de perfusão, tal como uma imagem com graus de perfusão indicados por uma faixa de níveis de luminosidade, uma imagem de parâmetros de perfusão de cor ou uma curva de perfusão ou parâmetro de curva indicando a taxa de perfusão.
