Dear Colleague:

We would like to extend to you an invitation to become a member of Particle Therapy Cooperative Group - North America (PTCOG – NA), which is the North American chapter of the international PTCOG non-profit organization. This professional membership Society has been created to enhance collaboration between its members, create a platform for scientific exchange, and develop treatment guidelines, education, and training initiatives for particle therapy. The Society will take steps towards establishing a particle therapy clinical trial collaborative group, as well as instituting representation in industry technological innovations, involvement in health care politics (as it pertains to particle beam therapy), and improving relationships with other professional societies in radiation oncology. The society--in collaboration with PTCOG International--established a particle therapy journal in 2014.

Please find enclosed a copy of the application form and the criteria for each membership level. Completed membership applications may be submitted via fax or email.
