Abstract
trata-se de emissores individuais operados em múltiplos grupos em que cada um ilumina uma região de interesse entre o arranjo de emissor e o arranjo de detector, de modo que o cone de raios de radiação projetados sobre o arranjo de detector a partir de qualquer emissor único em qualquer grupo seja substancialmente separado de modo espacial dos cones projetados correspondentes a partir de todos os outros emissores no mesmo grupo. pelo menos a porção de roi do espaço 3d entre o painel emissor e o painel detector é representada por elementos de volume 3d (voxels), em que pelo menos alguns voxels representam porções respectivas de tal espaço que são cruzadas por porções correspondentes de uma pluralidade de raios de radiação, em que cada uma se estende a partir um respectivo emissor a um respectivo detector e são associadas a respectivos coeficientes de absorção representativos da característica de absorção de radiação de uma porção correspondente da roi. o processo de reconstrução de imagem é um processo iterativo no qual voxels vizinhos que têm coeficientes semelhantes calculados são combinados em voxels maiores, em que voxels vizinhos que têm coeficientes diferentes calculados são divididos em voxels menores, e novos coeficientes de absorção são calculados.
