Sample slices showing how combining different deformations affects the size, shape, and glandular distribution of the newly created morphed breast phantoms. (a) Coronal slice from the “base” breast; (b) coronal slice from the “target” breast; (c) combining the “base” breast glandular tissue smaller structures with the “target” breast glandular tissue larger structures and fitting it into a smaller “target” breast shell; (d) directly translating the “base” breast tissue into a resized smaller “target” breast shell; (e) directly translating the “base” breast tissue into the “target” breast shell; (f) rotating, nonlinearly skewing, and shrinking the “base” tissue toward the center of the “target” breast shell and combining with the larger structures of the “target” breast tissue; (g) rotating and shrinking the “base” breast tissue toward the center of the “target” breast shell and rotating the “target” breast shell; (h) rotating and nonlinearly skewing the “base” breast tissue, and then fitting it into a rotated and resized smaller “target” breast shell; (i) rotating and eroding the “base” breast glandular tissue and fitting it into a rotated and resized “target” breast shell; and (j) combining the “target” breast tissue smaller structures with the larger structures of the “base” breast and fitting it into a resized “base” breast shell.
