Abstract

resumo sistema e método de obtenção de imagem na tomografia de emissão de pósitron, uma janela de tempo (260) e uma janela de energia (225) são ajustadas dinamicamente, com base em um mapa de atenuação, taxa de contagem, aplicação clínica, fabricação da discriminação, e/ou fabricação da discriminação offline. os eventos de radiação detectados são filtrados usando as janelas de tempo e energia ajustadas dinamicamente nos eventos dispersos, eventos aleatórios e eventos verdadeiros. os eventos verdadeiros são inseridos para reconstrução da imagem, correção e análise de erro. 1/1
