Automatic motion correction for breast MR imaging

CS Zuo, A Jiang, BL Buff, TG Mahon and TZ Wong
Department of Radiological Sciences, Deaconess Hospital, Boston, Massachusetts 02215, USA.

In 29 gadolinium-enhanced breast magnetic resonance (MR) examinations, breast motion prevented accurate and efficient image processing. To compensate for global rotations and translations, an automatic motion correction method with a ratio-variance minimization algorithm was used to align images at multiple time points through an iterative process. This method reduced breast motion and improved the accuracy and efficiency of lesion detection.
