Figure 2. Geometric parameters used to characterize the shape and location of the (A) gadolinium volume and (B) simulated volume.

Figure 2

(C) Coverage was defined as the percentage of the simulated volume (vertical hatch) covered by the gadolinium (cross-hatch). (D) Leakage was defined as the percentage of the gadolinium volume (vertical hatch) that was outside the simulated volume (cross-hatch). (E) The mean and maximum edge distances were measured between the outer edges and the overlap of the gadolinium and simulated volumes. (F) The centroid shift was defined as the distance between the centroids of the gadolinium and simulated volumes.
