Metric Values Around Center

The following is a visualization of metric values around the center of the MRI brain slice. The location of the yellow dots on the plane parallel to the brain slice represents the two dimensional coordinates of the center of the ellipse with respect to the slice. The value that the points take in the z-direction or the direction normal to the brain slice represents the metric value that each location takes. In this case a lower metric value, meaning a point that has a distance closer to the brain slice in the normal direction is better and means that the ellipse is closer to the optimal location. This visualization is a square of locations with width of sixty pixels centered at the center of the image. It shows a gradual slope in towards a low metric value as the locations become closer to the center.
