“…CsI) which may have particular performance advantages over powdered phosphors. Also, the availability of larger area CCD devices has allowed the direct coupling of the phosphor to the CCD providing field coverage without the need for optical demagnification (Thunberg et al 1999).…”

“…A caracterização de sistemas de imagem usando MTF, NNPS e DQE requer o uso da abordagem de transformada de Fourier de sistemas lineares na descrição da transferência de sinal e ruído da entrada para a saída do sistema (Cunningham, 2000). O desempenho dos detectores usados em mamografia digital em termos desses parâmetros tem sido extensamente estudado (Thunberg et al, 1999;Evans et al, 2002;Samei et al, 2005;Samei et al, 2006;Dobbins et al, 2006;Ranger et al, 2007;Marshall, 2007;Ghetti et al, 2008;Monnin e Verdun, 2009;Marshall, 2009;Marshall et al, 2011;Bloomquist et al, 2014;Monnin et al, 2014;Michail et al, 2015;Marshall et al, 2016;Monnin et al, 2016;Makeev et al, 2019;NHS, 2019aNHS, , 2019bNHS, , 2019cNHS, , 2019d2019e;Wigati et al, 2021;Frederico e Banguero, 2023). 3 Fundamentos teóricos…”

“…Para cobrir completamente o tamanho do campo de raios X no paciente é necessário diminuir a imagem do cintilador. Isso pode ser feito com acoplamento de lente ou fibra óptica (Thunberg et al, 1999;Yaffe, 2010;Feng et al, 2020). Esse estágio de demagnificação pode reduzir o número de quanta secundários (Alikunju et al, 2023).…”
