On November 12 and 13, 1938 forty-eight x-ray technicians met in Lima, Ohio and signed an Affiliation Charter of the American Society of X-ray Technicians thus officially forming the Ohio Society of X-ray Technicians (Radiologic Technologists).

Six Ohio technologists have been presidents of the American Society of Radiologic Technologists. They are:
Rubygrant Pennell, R.T., Columbus (1954-55);
Wilbur J Huston, R.T. Sandusky, (1961-62);
Roland C. McGowan, R.T., Cincinnati, (1964-65);
Joan Parson, R.T., Massilon, (1984-85);
Julie Gill, Ph.D, R.T. (2013-2014).
Heather Moore, Ph.D, R.T. (2024-2025)
Roland McGowan, R.T. became Executive Director of the American Registry of Radiologic Technologists and Joan Parson, R.T. served the American Society of Radiologic Technologists in many capacities including her last position as Executive Vice President of Operations.
The 1938 meeting was considered the first Annual Meeting of the OSXT. Since its inception, annual meetings have been held by OSRT every year with the exception of the war years of 1943,1944, and 1945, and in 2020 during the COVID pandemic. Meetings have been rotated among the cities of Ohio. On March 2 and 3, 1957, the first Annual Educational Meeting was held in Columbus. That same year, the annual business meeting was moved to the fall.
In 1975 a Student Quiz Bowl competition was initiated as part of what was then called the Annual Educational Meeting. Teams from Radiologic Technology programs from across the state competed during the spring meeting rotated among Ohio cities until 1995 when the fall Annual Business and Spring meetings were combined into one meeting. The meeting was held each spring. It was called the Annual Meeting of the Ohio Society of Radiologic Technologists, and it included the annual Quiz Bowl competition. In In 2024, the board voted to go back the the two-meetings a year plan. There is again, a fall Business Meeting held in September, and a spring Student and Educator Symposium (SES) held in April each year.
The OSRT honors technologists who have offered long-standing and dedicated service to the Society. These honors include Life Membership, Honorary Membership, and Fellow Status. Members who meet the necessary criteria may be also be nominated for the Technologist of the Year Award. The invitational Guest Lecture Series was established in 1966. Starting in 1974 the lecture series was renamed the Penn-Hu-Mac Lecture Series in honor of the OSRT members who served as past presidents of the ASRT Rubygrant Pennell, Jay Huston, Rolland McGowen. Later Joan Parsons also served, so the lecture series was renamed the Penn-Hu-Mac-Par Lecture Series. Two more Ohians joined the ranks, Julie Gill and Heather Moore, so the lecture series was again renamed as the Past Presidents Lecture Series.
The Ohio Society of Radiologic Technologists publishes the Cardinal Rays, a newsletter distributed bi-monthly to members. In addition, the OSRT maintains this active web site with current information about the society and the profession.
