Abstract
An apparatus for correcting patient motion between views in a medical imaging device employing multiple views in the generation of an image, and where some view data is truncated as a result of the finite area of the detector array, establishes a last row in the matrix of data for each view prior to and independent of the truncation for the purposes of evaluating motion. The data prior to this last row is compared with the data from the previous view with repeated relative shifts between the data to determine a lowest difference sum. Several difference sums may be employed to determine a shifting amount including a fractional part of a row.
