Professor in Residence, Department of Radiation Oncology, UCSF
Dr. Faddegon is a board certified clinical medical physics who is internationally recognized for his research in developing and using Monte Carlo methods for treatment head simulation and dose calculation with an eye to improving accuracy and precision in radiotherapy. The overall objective of Dr. Faddegon’s research is to allow for more aggressive treatment in sites where side effects, local control, and even metastases are a problem through cost-effective solutions to improve the therapeutic ratio.
Current research includes developing TOPAS, the Tool for Particle Simulation, a collaboration of UCSF, MGH and SLAC supported by NIH to improve advanced simulation of proton therapy, and developing XPERT, X-ray Plus Electron Radiotherapy, adding electrons to intensity-modulated radiotherapy with x-rays to reduce serious side-effects of radiation, especially in children. Dr. Faddegon is also working to establish image-guided radiotherapy with portal imaging for more precise targeting of tumors and avoidance of critical structures.
Dr. Faddegons clinical responsibility is physics support of linear accelerators (linacs). This includes management, installation, commissioning, maintenance and quality assurance. Highlights of Dr. Faddegon’s published clinical development work at UCSF include developing the means to treat the whole body over a short distance (3 meters), developing new x-ray targets to reduce downtime that are implemented on linacs worldwide, implementing high precision graticules for patient localization, and determining the means to detect and correct defective circuitry in treatments using virtual wedges.
