Paper Abstract

An automated method based on maximizing a 2D correlation coefficient between images is proposed to realign consecutive images obtained in functional MR image sequences. Dynamic Gadolinium-enhanced osteosarcoma studies are analyzed to study the influence of interframe motion and assess the registration method. The alignment procedure is evaluated by subtraction of the pre-injection image and by factor analysis of medical image sequences. The effect of motion correction is demonstrated by both techniques and the correlation method is compared to a procedure based on external markers.
