Abstract
Methods, systems and computer-readable storage media relate to determining optimal treatment information. The methods may include determining a dose distribution for one or more target regions by applying a deformation parameter to a treatment plan dose distribution for a subset of a plurality of phases. The method may also include determining one or more dose parameters based on the dose distribution for the subset of the plurality of phases. The one or more dose parameters may represent a motion of the dose distribution over the plurality of phases for each region. The method may further include determining optimal treatment information based on the one or more dose parameters. The optimal treatment information may include optimal phase and associated dose distribution and the optimal phase may be a phase having a minimum total dose for the one or more target regions.
