To achieve high detection B0z.s+.
efficiency and excellent spatial resolution for incident gamma flux, Hs=!.tZ,
a specially fabricated thick microcolumnar CsI(Tl) scintillator #4//2N
was optically coupled to the CCD. A prototype SPECT imaging Q'+N72=
system was assembled by incorporating pinhole/parallel hole MmWJYF=
collimators in the design. BQS9q'u_
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
