Challenges in Clinical Small Field Dosimetry Using the CyberKnife®

June 18, 2020

Dr. Paolo Francescon, San Bortolo Hospital, Vicenza, Italy
Dr. Francescon achieved his Degree in Theoretical Physics in 1977. Since 1995 he is the Director of the Medical Physics Department of Vicenza General Hospital – Italy. Since 1988 he was given several teaching appointments in MS and Specialization/PhD courses in the Universities of Parma, Firenze and Padova. He is a full member of the AAPM and of the Italian Association of Medical Physics, co-chair of the AAPM Task Group 155 on the dosimetry of small fields.

Small field x-ray beam dosimetry comes with challenges including lack of lateral electronic equilibrium, source occlusion, high dose gradients, and detector volume averaging. In this webinar, Dr. Francescon will provide guidance on how these can be addressed for the CyberKnife® System.

Moderator: Dr. Jun Yang, Philadelphia CyberKnife Center, PA

Dr. Jun Yang received his PhD in medical physics and medical imaging processing in Bio-medical Engineering, University of Miami in 2006. He has participated in the founding of Philadelphia CyberKnife in 2006, the first CyberKnife Center in great Philadelphia area.

As the clinical associate professor at Drexel Univ. and professor at Fudan Univ, Dr. Yang has published many peer-review papers on physics, clinical and radiobiology focusing on SRS/SBRT. 

He serves as editorial board for a few journals.  Dr. Yang is a member of multiple professional societies.  He serves as a board member of the Radiosurgery Society and the chair of physics committee since 2012.  He also, serves as a board member for AERO since 2013. He has participated in many professional guidelines, such as the TG 277 AAPM-RSS medical physics practice guideline for SRS-SBRT, updated TG 135 CyberKnife QA, and white paper for radiosurgery physics etc.
