Evaluation of a Nonrigid Motion Compensation Technique Based on Spatiotemporal Features for Small Lesion Detection in Breast MRI

Figure 1

Motion detection on a transverse image. (a) Masking the data term: the green lines separate the boundary between masked and unmasked areas. (b) Color code describing motion from the interior of the image. (c) Motion in two directions determined without mask and (d) based on the mask from (a). The values for the standard deviation of the Gaussian presmoothing kernel and for the smoothness term are 𝜎=3 and 𝛼=500.
