Study on Precision Analysis and Simulation Test of Upper Slicing System

摘要

The multislice spiral computed tomography (MSCT) is famous for the small radiation, large volume scanning and quickly reconstruction, and it becomes the first choice in clinical examination. The upper slicing system is the main components of the optical system in MSCT. This paper focuses on the design of upper slicing slice system and its precision analysis to improve the precision of imaging. The error of slice thickness and ray center by bearings, screw and control system is analyzed and tested. Improving the precision of the upper slicing system contributes to determine the appropriate treatment methods to improve the success rate of treatment.
