On the Usage of GPUs for Efficient Motion Estimation in Medical Image Sequences
Figure 2
Example of motion estimation in a cardiac ultrasound sequence. (a) Original slice at end diastole. (b) Original slice at end systole. (c) Image (b) after alignment to image (a). (d) Estimated motion vector field, shown superimposed on (a). (e), (f) Images (a) and (c), respectively, with the endocardial contour superimposed. Note how the shapes are matched by the motion estimation process and all motion estimation and resampling were performed in 3D; a sample 2D slice is shown for clarity.
