IMAGE RECONSTRUCTION IN INTERLEAVED MULTI-ENERGY IMAGING
The present invention discloses a method for reconstructing an image obtained from kVp switched imaging of a body by acquiring a plurality of images at a first kVp defining a first image scan and a plurality of images at a second kVp defining a second image scan, wherein the plurality of images at t...

| description | The present invention discloses a method for reconstructing an image obtained from kVp switched imaging of a body by acquiring a plurality of images at a first kVp defining a first image scan and a plurality of images at a second kVp defining a second image scan, wherein the plurality of images at the first kVp are acquired interleaved with the plurality of images of the second image scan and by reconstructing an image from the first and second image scan, comprising determining at least one gradient location for at least two images in the first and second image scans, determining divergent gradient locations in respect of a same part of the body for said at least two images in the first and second image scans, tagging each divergent gradient location as an under sampling artifact, generating the reconstructed image from the at least two images in the first and second image scans by correcting for each tagged under sampling artifact. The invention further discloses an imaging system for imaging at least a part of a body by means of a first image scan and a second image scan and a computer program product. |
