To achieve high detection * PZ=$>r
efficiency and excellent spatial resolution for incident gamma flux, OygYP
a specially fabricated thick microcolumnar CsI(Tl) scintillator #X)s=Y&5!T
was optically coupled to the CCD. A prototype SPECT imaging *6h.#$\
system was assembled by incorporating pinhole/parallel hole mb#)w`<
collimators in the design. \ l:n
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
