1. A method for imaging a dynamic region of interest using a multi-row CT imaging system comprising: segmenting a region of interest; selecting two or more successive projections from a projection data set, wherein each of the two or more successive projections are acquired at the same view angle and axial position and comprise a portion of data corresponding to a projection of the region of interest upon a detector; averaging the portion of data of each of the two or more successive projections to produce an averaged portion; replacing the portion of data of each of the two or more successive projections with the averaged portion to create two or more respective averaged projections; combining the two or more averaged projections with the remainder of the projection data set to produce a formatted data set; and reconstructing an image from the formatted data set.
