Abstract
A method of optimizing delivery of a particle beam at a target is disclosed. The particle beam is delivered from an output device at a plurality of control points. In implementations, the method comprises delivering a substantially continuous particle beam about the plurality of control points, iteratively adjusting a delivery time of the substantially continuous particle beam about the plurality of control points, and processing to undertake at least one of (i) pre-defining energy layers based on one or both of the control points and a control point sampling frequency, or (ii) sorting the energy layers.

A method of optimizing delivery of a particle beam at a target, wherein the particle beam is delivered from an output device at a plurality of control points, the method comprising:
- delivering a substantially continuous particle beam about the plurality of control points;
- iteratively adjusting a delivery time of the substantially continuous particle beam about the plurality of control points;
- identifying an initial set of control points;
- providing a first group of optimized beams, wherein each optimized beam of the first group of optimized beams is configured to be output at a first control point and steered towards one or more energy layers that are associated with one or more monitor unit (MU);
- providing a second group of optimized beams, each optimized beam of the second group of optimized beams configured to be output at the first control point and having a reduced number of energy layers;
- increasing a number of the initial control points;
- and
- maintaining a total number of energy layers as one of equal to, more than, or less than a total number of energy layers associated with the initial control points during movement of the beam between the plurality of control points, wherein increasing the number of initial control points comprises adding one or more adjacent control points to each initial control point, the adjacent control point having a fraction number of the total energy layers or MU of the initial control point.
