【 摘 要 】

A high efficiency X-ray image detector was introduced in an x-ray imaging micro-tomography system. The detector is a visible light conversion type which consists of phosphor screen, straight-fiber (1:1) optics and scientific CMOS device. The obtained CT images show high reproducibility of X-ray linear absorption coefficient of test material (Cu/Al concentric pattern). The x-ray intensity could be reduced about 10 % of previous system with lens-coupled image detector system.
