A system for use to determine or evaluate a radiation treatment plan includes a processor configured for determining a spatially variable constraint, and imposing the spatially variable constraint on a healthy tissue. A system for use to determine or evaluate a radiation treatment plan includes a processor configured for determining a first position of a first healthy tissue, imposing a first constraint on the first healthy tissue based on the determined first position, determining a second position of a second healthy tissue, and imposing a second constraint on the second healthy tissue based on the determined second position, wherein the first constraint and the second constraint have different values. A radiation system includes a processor configured for determining a treatment plan using a spatially variable constraint on healthy tissue, and a radiation machine for performing a radiation procedure based on the determined treatment plan.
