Abstract

SISTEMA E MÉTODO. Um sistema inclui uma fonte que gira sobre uma região de exame e emite radiação que atravessa a região de exame, um arranjo de detector sensível à radiação que detecta radiação atravessando a região de exame e gera dados de projeção indicativos da radiação detectada, e um redutor de ruído de dados de projeção que reduz o ruído dos dados de projeção, onde o redutor de ruído reduz o ruído de uma projeção com base em uma série de fótons detectada para a projeção.
