• Determined that linear accelerator delivered volumetric modulated arc plans are comparable to CyberKnife plans for spine stereotactic body radiotherapy. Concluded that linear accelerator plans could provide the special procedure with shorter treatment times. • Investigated the best constant dose rate delivery for prostate and head-and-neck cases using volumetric arc therapy with linacs without the variable dose capability upgrade. • Found that energy-based inverse optimization, which includes electron density information to the objective function with the goal of minimizing energy deposited in the normal volumes, is more sensitive to changes in intensity-modulated segment parameters compared to the standard dose-volume-based inverse optimization. • Concluded that changes in inverse optimized plans with density-inclusion: energy-based and dose-mass-based, are equally as sensitive as dose-volume-based plans to changes in head-and-neck anatomy during radiotherapy treatment. • Investigated the inclusion of electron density information into the equivalent uniform dose formulation and used normal tissue complication probability modeling to determine the differences to the standard equivalent uniform dose. • Became proficient at using Pinnacle treatment planning systems for research projects. • Utilized Excel and MATLAB for data modeling and data presentation.
