Abstract
System includes a beam generator to generate beam(s) for patient treatment and a computing device that obtains three-dimensional image(s) of a target structure that repositions with respect to surrounding tissue of the patient. The computing device creates plan(s) including a first three-dimensional probability distribution of patient's position and a second three-dimensional probability distribution of the repositioned structure's internal position. The computing device combines the first distribution with the second distribution to generate a joint distribution and selects a probability level from the joint distribution. The probability level defines an enclosed surface. A distance defined between the surface and a point of origin in at least one direction is equal to a threshold value of a parameter of the repositioned target in the direction. The computing device projects the surface to a plane positioned relative to a direction of the beam for the generation of beam-specific planning target volume design output(s).
