To achieve high detection W<Ri(g-
efficiency and excellent spatial resolution for incident gamma flux, {?X:?M_
a specially fabricated thick microcolumnar CsI(Tl) scintillator [$]qJ~kz
was optically coupled to the CCD. A prototype SPECT imaging B5v5D[ o5
system was assembled by incorporating pinhole/parallel hole tw
k
collimators in the design. \&BT#8ELG
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
