To achieve high detection 6:v8J1G(< efficiency and excellent spatial resolution for incident gamma flux, HjGT{o a specially fabricated thick microcolumnar CsI(Tl) scintillator PgB=<#9 was optically coupled to the CCD. A prototype SPECT imaging a+A/l system was assembled by incorporating pinhole/parallel hole S&_ZQLiQ$ collimators in the design. qf2{Te1 这个microcolumnar 是什么意思？这一句该怎么翻译 ？ 谢谢了
