Abstract
A path of a particle beam is determined through a 3D planning treatment volume (PTV), wherein the PTV includes a set of slices in a depth order, and each slice includes a set of locations. For each slice, the set of locations are grouped into a set of lines along a selected direction, wherein each line is a straight line and includes a starting location and an ending location, and each line is connected to one or two other lines, and the connecting connects two lines to either the starting location or the ending location of the lines to form a tour, and the tours are connected through the slices in the depth order to form the path of the particle beam.
