Title: Innovations in Radiotherapy: The Contributions of Robert Lee MacDonald
Introduction
Robert Lee MacDonald, an accomplished inventor from Antigonish, CA, has made significant advancements in the field of radiotherapy. With a total of four patents to his name, MacDonald has focused on systems and methods designed to enhance the precision and effectiveness of radiation treatment planning and delivery.
Latest Patents
Among his latest patents is the development of systems and methods for planning, controlling, and delivering radiotherapy and radiosurgery using combined optimization of dynamic axes, known as the CODA cube. This innovative approach allows for the application of cost values in the CODA cube to optimize various angles, such as couch, collimator, and gantry angles, simultaneously. The resulting trajectories derived from the CODA cube demonstrate substantial improvements over conventional volumetric modulated arc therapy (VMAT), including a statistically significant reduction in maximum radiation doses to organs at risk (OARs) by 20.6% (p<0.01). Notably, the maximum dose to the brainstem was decreased by an average of 2.63 Gy (p=0.031), while the mean reduction in total monitor units was 8.6% (p=0.156).
Another noteworthy patent concerns coordinated radiotherapy for plural targets. This innovative radiation treatment planning system allows for the generation of treatment plans that efficiently treat multiple target volumes, optimizing the radiation delivery by not requiring every target volume to receive radiation from all beam directions. This flexibility enables beam shaping that significantly reduces radiation exposure to non-target tissues.
