Claim:
1. An apparatus for delivering a longitudinal column of dose to a region of interest of a patient for treatment, comprising: a position and tracking module to determine a patient position and to locate a region of interest for treatment, the position and tracking module determining a respective position location of one or more target voxels in one or more stacks of voxels in said region of interest; a scanning routine module to target each target voxel of said one or more target voxels in an energy deposition array within said region of interest to selectively provide a dose prescription to each said target voxel of said one or more target voxels, each said target voxel of said one or more target voxels being respectively located at a respective data point in said energy deposition array and being respectively located in a stack of voxels of the one or more stacks of voxels in said energy deposition array in said region of interest, each respective said data point being respectively located at a horizontal index of one or more horizontal indexes and at a vertical index of one or more vertical indexes at an associated depth in said energy deposition array, the scanning routine module determining respectively, for each vertical index of the one or more vertical indexes in said energy deposition array in said region of interest, an amount of a respective said dose prescription for each said target voxel of said one or more target voxels, each said target voxel being respectively located at a respective said data point in said energy deposition array and at a horizontal index of the one or more horizontal indexes and at a vertical index of the one or more vertical indexes in said energy deposition array; and a beam delivery device to deliver to each said target voxel in a said stack of voxels of the one or more stacks of voxels in said energy deposition array in said region of interest a longitudinal column of dose of ion particles in a plurality of beams, each of the plurality of beams in a respective said longitudinal column of dose being respectively delivered to said stack of voxels of the one or more stacks of voxels having an energy intensity of a respective determined said dose prescription for a respective said target voxel of said one or more target voxels at a respective said data point in said stack of voxels of the one or more stacks of voxels in said energy deposition array, the beam delivery device delivering one respective said longitudinal column of dose to one stack of voxels of the one or more stacks of voxels respectively located at one horizontal index of the one or more horizontal indexes and at one vertical index of the one or more vertical indexes in said energy deposition array before incrementing to another stack of voxels of the one or more stacks of voxels respectively located at the one vertical index and at another horizontal index of the one or more horizontal indexes or before incrementing to another stack of voxels of the one or more stacks of voxels respectively located at another vertical index of the one or more vertical indexes and at the one or a said another horizontal index of the one or more horizontal indexes in said energy deposition array to deliver another respective said longitudinal column of dose to a said another stack of voxels of the one or more stacks of voxels respectively located at the one or a said another horizontal index of the one or more horizontal indexes and at the one or a said another vertical index of the one or more vertical indexes in said energy deposition array within said region of interest.
