APPARATUS AND METHOD FOR ENHANCING SPATIAL RESOLUTION OF CT IMAGE AND CT IMAGING SYSTEM

摘要

The present invention provides an apparatus and a method for enhancing spatial resolution of a CT image and a CT imaging system, the method comprising: acquiring an original CT projection curve; performing deconvolution for projection data on the original CT projection curve in a tube sampling direction or a texture direction of the original CT projection curve; and reconstructing an image according to the projection data after deconvolution.
