Mission, and live our Values. These values-integrity, patient-centered, respect, accountability, and compassion -
must guide what we do, as individuals and professionals, every day.
Under the direction of the Director of Radiological Physics and the supervising faculties of the Medical Physics
Residency program, the resident will participate in structured learning and assist medical physicists in providing
clinical medical physics services to all aspects of radiation therapy treatments at Yale -New Haven Hospital and its
satellite facilities, which include, but not limited to, treatment simulation, treatment planning, patient dosage
calculation, equipment calibration, in vivo dosimetry, quality assurance, and other physical and technical tasks
performed routinely by clinical physics staff.

5 .3 Measure radiation leakage to ensure the facility shielding meets federal, state and local requirements
6. Assist Radiological Physicists in routine quality assurance
Develop and assist the implementation of quality assurance programs, and test these programs for
conformance with specifications established by the JCAHO, NRC and other regulatory agencies.
6 .2 Perform biweekly, monthly, and quarterly QA of Linacs and orthovoltage x-ray units
6 .3 Participate in annual Linac QA checks
6 .4 Identify safety issues with Linacs and other treatment equipments
6 .5 Perform IMRT and special procedure plan verification measurements
6 .6 Perform charts check and independent MU verification calculation
7. Professional development
7 .1 Develop abilities to function in the roles and responsibilities of an independent medical physicist
7 .2 Develop abilities to solve daily clinical problems and answer physics questions independently.
Develop abilities to interact with and educate as necessary radiation oncologists, medical residents,
dosimetrists and therapists.
Maintain up-to-date knowledge of developments in radiological physics, and introduces new
developments into Yale-New Haven Hospital through membership in scientific organizations, attendance
at scientific meetings, and reading of scientific journals
A Ph.D. in physics, medical physics, or a closely related discipline.
EXPERIENCE A candidate with a Ph.D. in Physics or in a closely related discipline should have a minimum of one (1) year of
post-doctoral training in Radiation Therapy Physics. A candidate with a Ph.D. in Medical Physics should have
completed graduate course work and thesis subject in Radiation Therapy Physics or one (1) year of post-doctoral
training in Radiation Therapy Physics.
Demonstrable knowledge of fundamental physics, advanced mathematics, advanced atomic and nuclear physics ,
basic anatomy, computer operation, and network basics. Strong analytic skills in analyzing and solving problems
encountered in the design and execution of radiation therapy. Good verbal and written communication skills.
The performance of the resident will be evaluated on a quarterly basis by the director of residency program and by
the supervising faculty of each clinical rotation. The objectives of each clinical rotation and the performance of the
resident toward achieving these objectives will be carefully evaluated and documented. Corrective measures, if
needed, will be communicated to the resident by the program director and follow -up evaluation will be performed by
the program director and supervising faculty.
In personal and job-related decisions and actions, consistently demonstrates the values of integrity (doing the right
thing), patient-centered (putting patients and families first), respect (valuing all people and embracing all differences),
accountability (being responsible and taking action), and compassion (being empathetic).
This is a training position and most of the work is performed under the supervision of radiological physicists on the
staff. The goal is that by the end of two year training period the candidate will have acquired enough knowledge and
experience to exercise discretion and independent judgment in developing methods and devices that facilitate the
accomplishment of treatment prescriptions in radiation oncology physics
