Title:
コンピュータ断層撮影装置及び画像再構成方法
Document Type and Number:
Japanese Patent JP5349008
Kind Code:
B2
Abstract:
A method and system for computed tomography were weighted data is used to reconstruct an image. The apparatus includes an x-ray source producing a cone-beam of x-rays, an x-ray detector disposed to receive x-rays from the x-ray source, a data collection unit, and a processing unit for processing the data using a weighting function using contributions from fan-beam and cone-beam weighting functions. The apparatus can produce images with reduced artifacts.
