To achieve high detection udD*E~1q
efficiency and excellent spatial resolution for incident gamma flux, d50IAa^p6J
a specially fabricated thick microcolumnar CsI(Tl) scintillator {0vbC/?]
was optically coupled to the CCD. A prototype SPECT imaging h0GdFWN
system was assembled by incorporating pinhole/parallel hole $^=jPk]+
collimators in the design. "gN* J)!x
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
