  1. EDUCATION AND TRAINING OF MEDICAL PHYSICISTS James A. Purdy, Ph.D. Professor and Director Division of Radiation Physics Department of Radiation Oncology Washington University School of Medicine St. Louis, Missouri, USA Evolving Strategies in Radiation Oncology Rome, Italy,June 3-5, 2004

  2. EDUCATION AND TRAINING • Education of the clinical radiation oncology physicist can be divided into three stages. • 1st Stage: University education in physics, engineering, mathematics, and other relevant topics (B.S.). • 2nd Stage: Graduate education leading to M.S. or Ph.D. (Medical physics courses may be introduced into curriculum). • 3rd Stage: Physics residency training in a clinical environment.

  3. EDUCATION AND TRAININGFirst Stage • Bachelors degree in physics or equivalent. • Medical physicists should be educated primarily as physicists (or biomedical engineers?) and be qualified and competent to apply the many branches of physics to continually evolving problems and situations which occur in medical environs of hospitals and clinics.

  4. EDUCATION AND TRAININGSecond Stage • Graduate degree ( Masters or Doctorate ) in physics or medical physics. • Masters program: typically, about 2 calendar years required. • Doctoral program: typically about 4 to 5 years required. • emphasis on developing research capabilities of individual

  5. EDUCATION AND TRAINING: Second Stage • Note! If medical physics Masters and Doctorate degree program, it should be subjected to the same scrutiny and approval requirements as all other graduate degree programs of the University.

  6. EDUCATION AND TRAINING Third Stage • Formal comprehensive training and experience in areas of clinical dosimetry, treatment planning, treatment aid design and fabrication, brachytherapy, radiation safety, special procedures, machine calibration, and quality assurance. • Length of clinical physics residency training period should be 2 years or longer.

  7. EDUCATION AND TRAINING Third Stage • Note! Graduate degree in physics or medical physics is no longer adequate by itself in order to work independently in a clinical situation. • Note! Informal “on-the-job” training working under the tutelage of a more senior medical physicist is no longer adequate.

  8. EDUCATION AND TRAINING Accreditation • Accreditation of graduate educational programs in Medical Physics • program conforms with standards that should result in its graduates being qualified for more specialized training or professional practice in clinic medical physics. • Establishes minimum levels of educational and training opportunities that must be offered by program.

  9. EDUCATION AND TRAINING: Accreditation • Clinical Physics Residency Programs are based on AAPM Report No. 36

  10. EDUCATION AND TRAINING: Accreditation • Commission on Accreditation of Medical Physics Education Programs, Inc. (CAMPEP) • degree programs in medical physics (11) • clinical physics residency programs (6)

  11. CAMPEP ACCREDITED DEGREE PROGRAMS • McGill University • University of Alberta - Cross Cancer Institute • University of British Columbia • University of California - Los Angeles • University of Florida • University of Kentucky Medical Center • The University of Texas - Houston Health Science Center (M. D. Anderson Cancer Center) • University of Texas HSC - San Antonio • University of Wisconsin-Madison • Vanderbilt University School of Medicine • Wayne State University

  13. EDUCATION AND TRAINING: Certification • Certification board performs several functions: • evaluates qualifications of candidates requesting examination in specific medical physics subspecialties. • arranges, controls, and conducts certification examinations. • grants and issues certificates in to applicants who have been found to be qualified by the board. • maintains registry of holders of such certificates. • serves medical and lay public by providing lists of names of certified medical physicists.
