To achieve high detection r$}M,! J
efficiency and excellent spatial resolution for incident gamma flux, ;75K:_
a specially fabricated thick microcolumnar CsI(Tl) scintillator Y~#m-y
was optically coupled to the CCD. A prototype SPECT imaging _0ki19rs
system was assembled by incorporating pinhole/parallel hole
&2[OH}4
collimators in the design. hp+=UnW
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
