Abstract

The waveguide screen, as the core element of the digital CT system, is composed of the microchannel array and the scintillator combination. Using the excellent X-ray absorption performance of high-lead equivalent glass empty tubes and combined with the preparation of microchannel array technology, a glass empty tubes array material with high X-ray absorption performance is prepared.The results show that the high lead equivalent glass empty tubes has good pulling ability, the microporous array size is uniform and controllable, the empty tubes array has high X-ray absorption performance, and has excellent imaging effect after filling the scintillators, which provides a new way for the preparation of the high-performance X-ray waveguide screen.
