Automatic motion correction for breast MR imaging

Radiology. 1996 Mar;198(3):903-6. doi: 10.1148/radiology.198.3.8628891.

Abstract

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.
