1. A method for reducing, in an image, motion related imaging artifacts, said method comprising: obtaining imaging data of an object using an imaging system; obtaining a motion signal indicative of motion in the object from the imaging system; determining a displacement and a phase of at least a portion of the motion signal using a computer; generating a matrix that includes at least one inspiration phase column and at least one expiration phase column using the computer; subdividing the inspiration phase column and the expiration phase column into a plurality of cells, each cell configured to store imaging data within a different displacement range; mapping the imaging data into the plurality of cells based on the displacement and phase of the imaging data; and generating, using the computer, an image of the object using the data within at least one of the cells.
