To achieve high detection \i\>$'f*z
efficiency and excellent spatial resolution for incident gamma flux, G++<r7;x
a specially fabricated thick microcolumnar CsI(Tl) scintillator N:~4>p44[
was optically coupled to the CCD. A prototype SPECT imaging JL>DRIR%NV
system was assembled by incorporating pinhole/parallel hole =sF4H_B
collimators in the design. 5&xbGEP$
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
