Abstract:

Radiotherapy that contains affluent physical mechanisms is the most primary approach for cancer treatment. Nowadays, about 2/3 of cancer patients are treated with body radiation. This kind of therapy reduces tumor and kills cancer cells by causing damage of DNA—fracture of single / double bond which can be quantified through physical deposition physically and biologically. In order to improve rgw local control rate of tumor, one of radiotherapy’s vital goals is to increase dose projection in target part as well as to reduce radiation to surrounding healthy tissues. However, due to the procedure is quite complexed, there exists uncertainty of dosage of projection, which renders this target a great challenge. In this report, it will illustrates scientific studies of precision medicine from three aspects: Monte Carlo simulation in dose calculation and imaging, tracking of tumor motion, and position verification of heavy ion beam.

Bio:

Chi Yujie, graduated from Shandong University in 2009, and got her Ph.D. in the Institute of Theoretical Physics of Peking University in 2014. From 2014 to 2017, she began her post-doctoral study of medical physics in University of Texas Southwestern (USTW) Medical Center; and in September of 2017, she was hired as an assistant professor in the Department of Physics of UTA. When in USTW, she calculated the transport of High Performance Particle by Monte Carlo basing on GPU and Parametric geometry, which practically applied to deposition of dose, cone-beam imaging and positron Imaging; she also developed a method of 3D tumor motion tracking used in clinical trial for high risk prostate cancer, an integrated supportive system for 4D dose calculation and self-adaptive planning, and the technology of 6D tumor motion tracking used in treatment of liver cancer. At the mean time of scientific studies, she also took professional courses of medical physics and accepted training of intensive clinical training to establish a knowledge system of medical physics. There are 8 SCI papers published or to be published in specialized journals such as PMB, etc., 11 conference papers, and 6 international conference reports.
