Abstract
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.
Claims20
A method of operating a radiation treatment system, comprising:
- modulating, by a processing device, 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.
A radiation delivery system, comprising:
- a mechanism to move about a target;
- a radiation source mounted to the mechanism to generate a radiation beam;
- and
- a processing device operatively coupled with the mechanism and the radiation source, the processing device to control modulation of 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 angles while the radiation source is moved continuously.
The system of claim 10, further comprising a collimator to shape the radiation beam directed at the target,
A non-transitory computer readable medium comprising instructions that, when executed by a processing device of a radiation treatment delivery system, cause the processing device to:
- modulate, by the processing device, 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
- deliver a plurality of independent two-dimensional (2D) sub-beam intensity patterns from a plurality of angles while the radiation source moves continuously.
