Leadership and Governance

The American Board of Radiology (ABR) is led by a team of ABR-certified volunteers who bring clinical expertise, strategic vision, and a shared commitment to advancing patient care through high standards in certification. Our leadership structure ensures we make thoughtful and collaborative decisions, aligned with the evolving needs of the radiology and medical physics communities.

Board of Governors (BOG)

The Board of Governors (BOG) oversees the organization’s fulfillment of the mission and is responsible for the corporate powers, business, and affairs of the ABR.

This oversight role is consistent with the fiduciary duties owed by the board members of a nonprofit organization: (1) the “duty of care” (taking care of the nonprofit by ensuring prudent use of all assets, including facility, people, and good will); (2) the “duty of loyalty” (ensuring that the nonprofit’s activities and transactions are, first and foremost, advancing its mission); and (3) the “duty of obedience” (ensuring that the nonprofit obeys applicable laws and regulations).

Frank, MD, is an endowed tenured professor of radiation oncology at The University of Texas MD Anderson Cancer Center, holds the Bessie McGoldrick Professorship in Clinical Research, and is a fellow of the American Brachytherapy Society (ABS), American College of Radiology (ACR), and American Society for Radiation Oncology (ASTRO). Dr. Frank is the executive director of the Particle Therapy Institute and deputy head of strategy for the Division of Radiation Oncology. Dr. Frank is among the first, if not the first, to use IMPT to treat head and neck tumors, and is the principal investigator of an NIH/NCI/Hitachi-sponsored multi-institutional Phase III randomized trial in advanced stage oropharyngeal cancer that compares outcomes after chemoradiation given by IMRT versus IMPT. Dr. Frank has over 300 peer-reviewed publications, has authored many book chapters, and recently published the first textbook on proton therapy.

Dr. Frank’s lab is studying the biologic enhancement factor of proton therapy and FLASH radiotherapy for both head and neck and prostate cancer, as well as MRI-Assisted Radiosurgery (MARS) as the next generation of prostate brachytherapy. Dr. Frank’s expertise in MRI radiotherapy has led to the development and FDA approval of multiple novel positive-contrast implantable markers for use in MRI-guided LDR and HDR prostate brachytherapy and external beam radiation therapy. As founder of the company C4 Imaging, Dr. Frank developed the MRI marker technology at MD Anderson, has been granted 31 national and international patents, developed three FDA-approved products, and established MARS at MD Anderson for the treatment of prostate cancer. He has funding from the NIH, the Prostate Cancer Foundation, the Texas Ignition Fund, Hitachi, and MD Anderson, and has also raised multiple rounds of private equity financing to advance the C4 technology.

Dr. Frank has served as the president and chair of the American Brachytherapy Society and is the 2023 recipient of the Ulrich Henschke Award, the highest honor awarded by the ABS on a practitioner of brachytherapy. Dr. Frank is also a 2023 Leadership Award recipient at the UT MD Anderson Cancer Center. At the ABR, he has served as chair for the head and neck section of the oral boards for radiation oncology.
