华人物理师志愿做贡献的人很多啊，感谢陈昱基金会给机会认可和感谢他们，也激励更多的人向他们学习。作为一名不太资深的潜水员，我知道了解的人不多，就是有限的这些人里，我都能想出不少我想提名的人，今年先提一个石成玉吧。 其实对老石我也所知有限，毕竟从未一块儿共事过。但自从他开创了物理师公众号之后，三不五时发布的那些或诙谐或有用的小文为咱群注入了很多的生命力，也无形中拉近了那个我老记不住长名字的官方组织与我等升斗小民的距离，很亲和也颇为正能量。另外老石多年来也很热心公益，无论是咱群里答疑解惑帮忙啥的，还是咱行里作杂志编辑评审人啥的，都做得很多。我第一次接触到他的名字，就是他找我审稿一篇JACMP的文章。那时候还在为申请绿卡攒审稿，因为是我第一篇来自陌生人的审稿邀请，记忆深刻。还有就是我知道老石帮着拉队伍找北美这边的物理师给国内学校 webex客座讲课了。总而言之，有限的接触了解，不妨碍我片面地认识老石同志的杰出贡献，特此提名。请更了解他的同志们补充。

Jason Yan (St. Joe in Phoenix)

Jason Yan 过去几年一直从事义工活动，举办了武汉大学的视频讲座，并建立了微信群来联系国内和国外医学物理师的交流。同时建立了网站来共享视频。在他的影响下，国内物理师已经得到很好的交流平台。同时，他积极联络国外物理师来进行国际交流，任劳任怨。在自己工作繁忙同时，非常热心地回答国内物理师的问题，并积极提问和共享信息。这种精神符合陈昱基金会的精神。

Raymond Wu (retired)

他现在退休了、但好像差不多是全职在做义工吧？ 他是IMPCB国际义工组织的CEO, 致力于在全世界内推广医学物理师的认证工作及相关工作。他也时常在国内物理师群里帮忙回答问题。去年作为介绍人、帮助国内十名物理师取得了AAPM国际会员的资格、其过程费时很多。他也参与了两趟网络课程的授课、授课被录下视频免费供华人物理师们学习。

Dr. Quan Chen, the Associate Professor of Radiation Medicine at the University of Kentucky

Dear Yu Chen Memorial Foundation and NACMPA, I would like to nominate Dr. Quan Chen, the Associate Professor of Radiation Medicine at the University of Kentucky for the Yu Chen Memorial Award. I have known Dr. Quan Chen for over five years and I strongly support Dr. Quan Chen’s nomination. I am currently an Assistant Professor in the Department of Radiation Oncology and Molecular Radiation Sciences at the Johns Hopkins University. I am also the lead physicist of proton therapy (under construction), thoracic service, MRI imaging and ultrasound guidance in our department. I first met Dr. Quan Chen when he interviewed for the faculty at University of Virginia Radiation Oncology in 2011 when I was the first-year medical physics resident there. I was indeed impressed by his accomplishment as a lead medical physicist in the field. He received his PhD degree in Medical Physics in 2004 from the University of Wisconsin – Madison, one of the best programs in the country. During his graduate study, he published many pioneered ultrasound imaging papers with very high impact journals in the field including IEEE Transactions on Medical Imaging and Ultrasound in Medicine and Biology. His talk on his original work on the GPU based TomoTherapy treatment planning system received tremendous praise and very high respect from the department colleagues. His invention and research work on this topic has been commercialized and is now widely used in clinical practice which revolutionized the TomoTherapy workflow. I got to know him better after he joined the faculty of medical physics in Radiation Oncology at the University of the Virginia in the same year. During my second year of medical physics residency training, Dr. Quan Chen served as my research and clinical mentor. Together with Dr. Quan Chen, we have developed a novel cone beam CT and deformable image registration imaging method to quantify radiation-induced pulmonary injury in pre-clinical animal models. Dr. Quan Chen introduced me to the research group who worked on fast and low-dose 4D cone beam CT at the University of Wisconsin. By collaborating with them, Dr. Quan Chen and I were able to significantly reduce the 4D cone beam CT imaging time and dose for its use in the pre-clinical studies. Our work received a lot of interest at the 54th AAPM annual meeting. Because of our work on pulmonary injury studies on the preclinical imaging system, in February 2013 I was recruited to continue this research at Johns Hopkins University who put a lot of research resource on the preclinical imaging and radiation system. Dr. Quan Chen supervised me and we worked closely on both clinical and pre-clinical research projects. He showed his leadership as a senior researcher and a deep thinker. He led the TomoTherapy transit dosimetry research group and I was able to learn the basics from exit detector physics to the patient dose reconstruction algorithm. With Dr. Quan Chen’s supervision, I worked together with TomoTherapy and MathResolution research teams and we were able to implement the first generation of transit dosimetry and pre-treatment QA with in-air delivery on the TomoTherapy systems. Dr. Quan Chen led my research effort and improved the potential clinical workflow. His ideas on the exit detector measurement have a significant impact on the research projects on TomoTherapy. At the same time, he continued his excellence in Monte Carlo dose verification research after joining the University of Virginia. By utilizing the cloud computing, we were able to achieve much faster calculation time and we translated it into daily clinical deployment. Our work was presented at 2012 AAPM annual meeting and other institutions later joined the development and clinical practice on this project led by Dr. Quan Chen. Dr. Quan Chen is an excellent teacher. In the daily clinical practice, his office is always open to the residents and students. He supervised me and another physics resident on the commissioning of Varian True Beam linear accelerator with the high dose rate flattening filter free mode. He educated us on how to establish and maintain the daily, monthly and annual quality assurance for our radiation delivery machines. I’m fortunate enough to learn from Dr. Quan Chen, the brain behind our first clinical TomoHD and GPU treatment planning system. He also taught me how to clinically implement the deep breath-hold motion management technique with onboard biofeedback bellow system. This experience has helped me to setup my current motion management practice using real-time ultrasound imaging at my current institution. Dr. Quan Chen is very well organized, detail-oriented, and trustworthy. From Dr. Quan Chen’s mentorship, I believe every resident and student will be inspired by his or her academic career and will treat every patient as their own family member. Dr. Quan Chen is pleasant to work with and I find him to be a very kind individual who is willing to help in every aspect. His dedication and spirit were greatly appreciated among physicist and physician colleagues. I was deeply touched when I saw the bio of Dr. Yu Chen - "Had Dr. Yu Chen lived on, he would still be helping everyone in need without reservations". Dr. Quan Chen carries exactly the same spirit as Dr. Yu Chen. Every year at the AAPM annual conference, I saw so many young physicists like me coming to him and thank him in person with deep gratitude. I strongly recommend Dr. Quan Chen for the Yu Chen Memorial Award. He is a great asset to our community and he helps the young physicists to build their careers with dedication and passion. Please do not hesitate to contact me with any further questions. Respectfully, Kai Ding, Ph.D., DABR Assistant Professor Department of Radiation Oncology and Molecular Radiation Sciences Johns Hopkins University 401 North Broadway, Suite 1440 Baltimore, MD 21231-2410
