Station parameter optimized radiation therapy (SPORT): a novel scheme for treatment planning and delivery in radiation therapy
Stanford researchers have discovered a novel scheme of treatment planning and delivery of radiation therapy, termed station parameter optimized radiation therapy, or SPORT. It achieves highly conformal dose distributions through optimal beam sampling and intensity modulation and at the same time maintains high delivery efficiency.

Applications
- Treatment planning and delivery techniques in radiation therapy
Advantages
- Can be delivered by commercial medical linear accelerators without modifying existing system hardware
- Achieves optimal dose distributions by non-uniform angular beam sampling, and/or non-isocentric beams, and/or sparse intensity modulation
- Fast delivery by eliminating dispensable intra-beam intensity modulation using novel compressed sensing strategies for dose optimization and planning
