1. A method for designing a radiation treatment for a subject using single arc dose painting, comprising:

  • providing an unconstrained optimization map which supplies intensity profiles of densely-spaced radiation beams;

    aligning each intensity profile to a pair of multiple leaf collimation (MLC) leaves;

    applying a shortest path algorithm to convert each pair of MLC leaves to a set of leaf aperture sequences, said set of leaf aperture sequences forming a shortest path single arc thereof;

    andconnecting each single arc of leaf apertures to form a final treatment single arc path, thereby designing the single arc dose painting radiation treatment; and

    delivering a treatment dose of radiation to the subject during a single rotation along one or more of the final treatment single arc path.
