Left: Illustration of three spatial regions: Center, middle, and periphery. Middle and right: An example of the sDVH from a clinical prostate case treatment plan. The sDVH shows how underdosed voxels and overdosed voxels are distributed.
DVH and sDVH for two prostate plans. On the DVH figure, plans 1 (solid line) and 2 (dashed line) have virtually identical target DVHs. The sDVH provides additional spatial information as can be seen that in plan 2 almost all underdosed voxels are at the periphery and middle region, while plan 1 has some underdosed voxels in the center region as well.
Multivariable NTCP, TCP, and figures. The “” marks the values’ locations used in the Biological Evaluation module. Examples here are: Top-left: Logistic NTCP as a function of and ; top-right: LKB NTCP as a function of and n; bottom-left: Poisson TCP as a function of and ; and bottom-right: as a function of rectum’s and PTV’s .
Three SABER models for calculation of TCP, NTCP, and . Abbreviations: equivalent uniform dose; normalized to 2 Gy fractions; dose in 2 Gy fractions; control probability; tissue complication probability; and TCP.
NTCP results from the three SABER models for five prostate and five head/neck plans.
