A radiation delivery system and method of operation are described. The method includes modulating a sub-beam intensity of a radiation beam generated by a radiation source across a plurality of sub-beams that subdivide a fluence field into a two-dimensional (2D) grid, and delivering a plurality of independent two-dimensional (2D) sub-beam intensity patterns from a plurality of angles while the radiation source is moved continuously.

Delivering independent 2D sub-beam intensity patterns from moving radiation source

A system for delivering radiation dose, includes a gantry to move about a target to be irradiated and a radiation source mounted to the gantry and directed inward toward the target, The system further includes a collimator mounted to the gantry and in front of the radiation source, the collimator to shape a radiation beam directed at the target, wherein the collimator is to modulate a sub-beam intensity of the radiation beam across a plurality of sub-beams that subdivide a fluence field into a two-dimensional (2D) grid, and wherein a plurality of independent two-dimensional (2D) sub-beam intensity patterns are delivered from a plurality of gantry angles while the gantry moves continuously.
