Reduction of movement artifacts in comparative 3D magnetic resonance (MR) breast imaging

The problem of mis-registration of 3D datasets is addressed for MR imaging of the breast. Three methods are examined and qualitative evidence of their performance is presented. A method of constrained principal axis determination is compared with a correlation method, and an orthogonal polynomial approach is extended into three dimensions. The most effective methods still remain relatively time consuming, and for the correlation method, parallel distributed computing has been applied to reduce the time-to-solution.
