The FLASH Workshop 2024 in Heidelberg at the German Cancer Research Center (DKFZ) brings together medical physicists, biologists, clinicians and scientists to discuss the impact of oxygen in FLASH radiotherapy (FLASH-RT). Oxygen plays a vital role in radiation therapy, since it's the most well-known radiation sensitizer. Increased tissue oxygen has been shown to reduce the protective nature of FLASH in healthy tissue. The FLASH workshop will allow for an open discussion of the ideas of how oxygen impacts FLASH-RT. Talks by our invited speakers will be supplemented by talks of attendees. Therefore, we are really looking forward to your abstract if you want to actively participate in the workshop. 

The workshop is organized by DKFZ under the auspices of the Heidelberg Institute for Radiation Oncology (HIRO).

Confirmed Speakers: 

Marie-Catherine Vozenin (Geneva, Switzerland), Pierre Montay-Gruel (Antwerpen, Belgium), Elke Beyreuther (Dresden, Germany), Kristoffer Petersson (Oxford, UK), Cristian Fernandez Palomo (Bern, Switzerland), Charles Limoli (Irvine, CA, UAS), Prof. P. Jack Hoopes (Hanover, NH, USA), Prof. Billy W. Loo Jr. (Stanford, CA, USA)


Medical physicists, biologists, clinicians, bioengineers and students in the respective fields
