Open publisher page 0 citations

Abstract

Objective To study the measurement technique of multi slice CT system, and evaluate the image quality. Methods Catphan phantom and IRIS software were used to characterize parameters such as high contrast resolution, low contrast resolution, slice thickness, noise, CT numbers, etc. Results Linear interpolation method and pitch affect the image quality of multi slice CT. Conclusion Multi slice CT can provide equivalent image quality at 2 to 3 times the volume coverage speed of the single slice CT. It will be the most important trend for CT system development.
