Abstract
a presente invenção se refere a um detector de radiação de conversão direta, sendo que o material de conversão direta compreende uma granada com uma composição de z3(alxgay)5o12:ce, onde z é lu, gd, y, tb, ou combinações dos mesmos, e onde y é igual ou maior do que x; e, de preferência, z compreende gd. as granadas adequadas convertem diretamente radiação, como raios x ou raios gama, em sinais eletrônicos. de preferência, a fotoluminescência da granada é baixa ou ausente. o detector é particularmente adequado para uso em dispositivos de imageamento por raios x, como tomografia computadorizada. em algumas modalidades, a fotoluminescência de granadas pode ser usada para construir um detector de conversão direta-indireta híbrido, o qual pode ser particularmente adequado para uso com pet de tempo de voo.
