Medical Physics

UT Southwestern Radiation Oncology’s physics expertise will be strongly represented at the annual Ameri- can Association of Physicists in Medicine (AAPM) meeting in July in DC. Among 58 accepted abstracts, 26 are orals, 10 are snap orals, 6 are electronic posters and 16 are general posters. Notably, David Chiu has one abstract chosen as Best in Physics in Joint Imaging and Therapy (one of top five scored abstracts in that cat- egory). You Zhang has one abstract chosen as a Young Investigator Symposium finalist (one of top 10 scored abstracts from 391 submissions). Electronic posters
