The Penn-Ohio chapter held its annual Fall Meeting in Mayfield Village OH October 13-14, 2017. The theme of the meeting was "Online Imaging for Radiotherapy." Research presentations from six trainees (masters students and residents) opened the proceedings. In keeping with the theme, Anthony Magnelli (CCF) then spoke on using kV imaging throughout treatment to track fiducial markers and Rick Jesseph (UH) introduced us to the imaging and motion management techniques used in proton therapy.

A poster and social session began after the talks, with a chance to reacquaint ourselves with colleagues from our chapter. For our Night In, there was a pertinent talk over dinner by Ehsan Samei (Duke) on MedPhys3.0. This is a vital subject for all medical physicists, and as would be expected, the talk generated over an hour of lively discussion. Many ideas were formulated on how we could demonstrate and increase our value in our profession and to physicians and administrators.

After Saturday's breakfast, Dr. Samei returned to supply an example of how physics is improving diagnostic imaging, detailing his research of tangible tools for dose and image quality monitoring. Our keynote speaker was Allen Li from the Medical College of Wisconsin, outlining their newly installed MR-linac. These machines will become the standard for online imaging for radiotherapy, and it was exciting to see the promise they hold. Concluding the online imaging theme, Tarun Podder (UH) presented specifics of motion management for SBRT, and Ping Xia (CCF) detailed the use of real-time ultrasound to monitor intra-fraction motion of prostate and liver tumors.
