To achieve high detection ZrsBm_Rx
efficiency and excellent spatial resolution for incident gamma flux, I}1NB3>^
a specially fabricated thick microcolumnar CsI(Tl) scintillator >m$1Xx4#GV
was optically coupled to the CCD. A prototype SPECT imaging 02c':a=7
system was assembled by incorporating pinhole/parallel hole KrQ1GepJ
collimators in the design. A~)D[CV
这个microcolumnar 是什么意思?这一句该怎么翻译 ? 谢谢了
