The Diagnostic and Nuclear Medical Physics Residency at Cleveland Clinic aims to provide the highest quality training in all areas of imaging physics. The residency was first established in 2016 as a two-year training program in diagnostic medical physics. This two-year program was accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP) in November 2017. In 2019, the program expanded to include an additional year of training in nuclear medicine. The combined three-year program has been accredited by CAMPEP since August 2020.

With a strong clinical focus, the program is designed based on the CAMPEP standards and the recommendations of the AAPM Report No. 249. Residents, under the supervision of board-certified medical physicists, perform the following training activities:

  • Acceptance, annual, and post-repair testing of imaging equipment to ensure quality, safety, and regulatory compliance.
  • Troubleshooting of image artifacts and other quality and safety incidents.
  • Radiation dose tracking and protocol optimization.
  • Accreditation data collection, site planning, site inspection, and equipment purchase.
  • Patient/conceptus dose estimation, shielding calculation, and general health physics training.
  • Shadowing of technologists and radiologists to understand how medical physics practice affects other healthcare providers.
  • Attending and assisting in teaching conferences, quality assurance committee meetings and clinical/research seminars.
  • Conducting research and presenting findings at local or national conferences.
  • Teaching medical physics to other healthcare providers.

The residency training experience can be used to qualify for the certification examinations by the American Board of Radiology (ABR) in diagnostic and nuclear medical physics and the certification examination by the American Board of Science in Nuclear Medicine (ABSNM).

The rotation mentors devote substantial time and efforts to training residents, as evident by the various elements of a clinical rotation:

  • A resident’s initial experience with equipment testing in a given modality is always supervised by a rotation mentor (a board-certified physicist). The mentor not only introduces the testing procedures, but also explains and quizzes the resident on the rationale behind each test. They also discuss the related regulations and standards. Subsequent training in equipment testing is also provided mostly by rotation mentors with other experienced individuals (e.g., quality assurance technologists and senior residents) acting in a supplemental role.
  • In most modalities, a resident progresses through four training levels: (1) observe and assist, (2) test under close supervision, (3) test with occasional assistance, and (4) test independently.
  • For selected modalities (e.g., radiography, fluoroscopy, and ultrasound), equipment testing does not require the presence of a certified physicist. For such modalities, a resident will be issued a Certificate of Independence once they’re deemed qualified to test independently (Level 4). At this level, a resident is also the lead person to handle all the scheduling and communications. Several periods of Practice of Independence are built into the training schedule to allow a senior resident to practice working independently. In addition, there are frequent opportunities for a senior resident to lead the investigation of an image quality issue. Such opportunities develop key skills of critical thinking, problem-solving, and communication. They allow the residents to experience at firsthand how their knowledge and skills can make a difference in patient care.
  • Residents with adequate teaching skills may also advance to Level 5, where they mentor a junior resident in the absence of a rotation mentor.
  • The curriculum is designed to provide sufficient experience for a resident to obtain the following mammography credentials before graduation: (a) FDA requirements for 8 hours of initial training in digital breast tomosynthesis, (b) FDA and ACR requirements for stereotactic breast biopsy, and (c) Ohio Certified Radiation Expert (CRE) in mammography.
  • On a weekly or biweekly basis, the rotation mentors have sit-down didactic sessions with the residents. Topics discussed include (a) the fundamental principles of the image modality, (b) practice-based skills (e.g., image artifact troubleshooting, structure shielding design, and patient dose calculation) and (3) special interest topics (e.g., radiation dose tracking, protocol optimization, and equipment purchasing). Residents are asked to complete an assignment or a reading list before each didactic session. During the session, the mentors quiz the residents frequently and ask them to teach mini-topics on a white board. This evaluates the residents’ understanding of the subject material and provides them with ample opportunities to practice oral presentation skills.
  • To enhance the residents’ awareness of and responsiveness to the larger system of health care, mentors arrange for the residents to shadow (a) patient imaging procedures, (b) technologist quality control, (c) radiologist interpretation, and (d) internal and external audits and inspections.
  • Training in each rotation also includes an oral presentation to the entire Section of Medical Physics. The rotation presentation is intended for a resident to delve deep into a particular clinical topic and for the group to learn from the resident’s oral report.

  • Each rotation ends with two competency tests, an oral test in medical physics knowledge and a hands-on test in equipment testing skills. A separate assessment of professional behavior completes the evaluation package.
  • Finally, a modality revisiting scheme is in place to allow a resident to revisit earlier rotations to keep their knowledge and skills fresh.

The above training elements ensure that the residents are progressively trained and rigorously evaluated in six core competency areas specified by the American Board of Medical Specialties (ABMS) and the Accreditation Council for Graduate Medical Education (ACGME):

  • Patient care and procedure skills.
  • Medical knowledge.
  • Practice-based learning and improvements.
  • Interpersonal and communication skills.
  • Professionalism.
  • Systems-based practice.

In addition, a comprehensive orientation program is designed to provide training in safety, ethics/professionalism, leadership, and informatics.

At the resident’s request, mock oral exams, emulating the style of the ABR Part III exams, are provided at the end of the residency.


As a clinically focused training program, our residency does not offer protected research time. It may not be suited for individuals with strong interest in academic research. However, applicants enjoying clinical research and troubleshooting in a clinical environment will find the training experience stimulating and rewarding.

At the beginning of their second year, a resident is provided with a list of potential projects, divided into two categories: research projects and practical quality improvement (PQI) projects. Research projects require more efforts, are longer-term, and are more likely to result in conference abstracts. PQI projects are short-term efforts that aim to address ongoing clinical needs. A resident should choose a single research project. In addition, he or she is welcome to take on any number of PQI projects provided that the resident’s clinical training is in good standing. Before making a final decision, the resident is strongly advised to discuss the projects of interest with the mentors to get more information about the projects as well as the mentor’s expectations and mentoring styles.

While collaboration with other trainees, such as graduate students and radiology fellows, is encouraged, the majority of the work on literature review, data collection, analysis, and presentation should be conducted by the resident. To ensure a productive effort, the resident is required to submit at least two conference abstracts in the three-year training period.

By engaging in research and PQI projects, the resident is exposed to the entire process of:

  • Recognizing patient care challenges that can be addressed by scientific studies,
  • Applying scientific methodology to solve problems, and
  • Communicating scientific ideas through writing and speaking in a public forum.

Download sample research presentations the residents have given at professional conferences.


Residents participate in teaching conferences, quality assurance committee meetings, clinical/research seminars, and journal clubs. A list of required and recommended activities can be found below:

By participating in these activities, the residents:

  • Broaden their knowledge about the fields of radiology and medical physics.
  • Interact with caregivers in related disciplines.
  • Enhance their communication skills.
  • Develop a habit of life-long learning.


Residents are highly encouraged to teach, especially during their second and third years of training. Examples of resident teaching activities include

  • Teaching 2-3 physics lectures to the radiology residents.
  • Assisting program faculty in teaching hands-on labs to the radiology residents.
  • Providing fluoroscopy hands-on training to physician fellows and residents.
  • Providing radiation safety training to technologists and nurses.
  • Offering in-service training to technologists during the transition to ACR digital mammography QC manual.
