Each year, CARTI offers a medical physics radiation oncology residency program to prepare students entering the field of medical physics. This program is CAMPEP accredited.

This 24-month program will be strongly clinical and professional, not didactic. CARTI will offer the resident a dynamic clinical learning environment and a vigorous and aggressive adoption of new and proven technology.

Physics Resident Program Information


Pre-Requisite Requirements:

Applicants must satisfy the following criteria in order to be considered for acceptance into the residency program:

Graduate of a CAMPEP approved Medical Physics program with a Masters or Doctoral degree.
Graduated with at least a 3.0 cumulative overall GPA.
Meets CARTI employee requirements.
Application Process:

CARTI is participating in the AAPM Common Application Program and MedPhysMatch. Please see the following website for more information: http://www.aapm.org/CAP/

The position will be posted by November 1st.


The physics residency program is designed to handle a maximum of 2 residents. One resident is accepted per year.


Upon entering the program, the resident will be given a residency handbook that contains all resources, opportunities, and requirements for successful completion of the CARTI residency program will be explained. The program director and all staff physicists will always be available to answer questions and give clarification should the resident request it. In addition, the resident will be given his/her own CARTI employee manual.

During the two year residency program, continuing education will be required on a monthly basis. This continuing education is the same as that required of CARTI employees and covers areas such as radiation protection, patient confidentiality, infection control, and clinical expectations.


Residents are monitored throughout the program by the program director. Residents will meet with the program director, as well as the assigned resident mentor, at least once a month. In addition, at the completion of each rotation the resident will receive written feedback on their performance. By the completion of the residency, the physics resident is expected to be able to perform all radiation oncology physics functions.


The medical physics residency position at CARTI will be a full-time salaried new employee. As such, this position will qualify for the same benefits as any other new employee, including health and dental insurance plans, CARTI holidays, paid time off, 403 B tax deferred annuity and retirement plan (the retirement plan is not fully vested for 5 years). This position also includes paid registration, travel and lodging, and meals to one meeting or workshop each year, and membership dues to one related professional society. Transportation to CARTI sites outside of Little Rock is provided by CARTI, or reimbursed at the current mileage level set by CARTI.

All other financial burdens are the responsibility of the resident, including all travel and living expenses, out-of-pocket health care, books, supplies, uniforms/lab coats, etc.

Training Requirements


The requirements for completion of the residency will be the demonstrated ability to perform independently all tasks generally recognized as fundamental clinical physics duties, as outlined in Task Group 249 of the AAPM. The residency program will be of 24-month duration. The objective of the first year will be the attainment of the ability to manage, with necessary supervision from the CARTI clinical physics staff, the broad range of clinical duties necessary for the daily operation of a radiation oncology clinic; primarily the safe planning and delivery of radiation therapy to cancer patients, state licensing maintenance, radiation safety issues, etc. The objective of the second year will be to build on the first year and to develop areas of specialization and expertise, and to develop a greater level of responsibility and independence.

One advantage that CARTI offers residents is its multiple (6) clinical sites, each staffed with its own radiation oncologist(s), dosimetrist(s), therapists, and administrative staff. It is expected that in the second year of the residency, the resident will join the clinical travel rotation with the other staff physicists. This will enhance the resident’s ability to work independently; while at the same time have access to support from the other physics staff. It is expected that the resident will attend or participate in departmental and clinical conferences, in-services, and e-learning programs which have direct or indirect educational or clinical relevance. Examples of ongoing conferences are:

·  weekly physics staff meetings

·  weekly chart rounds

·  weekly stereotactic conference

·  weekly radiation oncologist case review

·  monthly medical physics journal club

·  monthly e-learning clinical programs


·  Introduction to the Treatment Process

·  External Beam Treatment Planning and Delivery (non-SRS/SBRT)

·  Linacs, Treatment Planning Systems, and Radiation Detection

·  Brachytherapy



·  Imaging in Radiation Oncology

·  Education, Communication, and Research

The method for evaluations of the resident’s performance in each clinical rotation will be determined by the CARTI physics staff. Possible methods for evaluation will be

a) oral exams
b) written exams
c) performance of a specific task (e.g. independent performance of annual calibration)
d) oral presentations by the resident to physics or other staff
e) journal article reviews

Program Administration


The program director is Joe Grant, M.S., DABR. The associate program director is Bobby Mathews, M.S., DABR.

The program director will be responsible for maintaining routine documentation for compliance with CAMPEP certification, directing annual and quarterly reviews of the residency program with the residency advisory board, and conducting monthly reviews with each resident to assess progress through the program. The program director will also delegate mentoring responsibilities to the staff physicist on a monthly rotating basis.


The following standing committees will meet as needed, but at least annually.

1. Admissions Committee
2. Medical Physics Residency Review Board

The admissions committee will meet starting in December of each year to begin the review process, and to interview new program applicants. It will continue to meet as necessary until an offer has been made and accepted by an applicant. The review board will review the entire program annually and make changes to the curriculum, rotations, and competencies based on feedback from the faculty, residents, and other staff. Quarterly reviews will be conducted by the review board to address any pressing matters that may arise.

Committee Members include:
Paul Bruce, M.S. DABR
Joe Grant, M.S., DABR
Bobby Mathews, M.S., DABR
Scott Yakoubian, M.S., DABR
Vance Keeling, M.S., DABR
