Abstract

A method includes obtaining projection data from a scan of a moving structure of interest. The method further includes reconstructing the projection data, generating first image data. The method further includes identifying a sub-set of the projection. The method further includes reconstructing the sub-set projection data, generating second image data. The method further includes identifying a region in which the moving structure of interest is located based on the first image data. The method further includes identifying a location of the moving structure of interest in the identified region based on the second image data.
