A rapid range stacking for particle beam therapy includes a position and tracking module used for a patient position and locating a region of interest, and a scanning routine module used for targeting a target voxel within the region of interest by accessing a treatment plan characterization while providing a prescribed amount of dose to the target voxel. The scanning routine module determines a prescribed amount of dose for the target voxel by incrementing a position location of horizontal indexes on a single vertical index. Further, a beam delivery module used for controlling a beam device delivers ion particles to the target voxel within the region of interest. The beam delivery module controls a power supply for a horizontal magnet and a vertical magnet by retrieving information from the scanning routine module, and also controls a power supply for an accelerator energy selection.
