B.S. in Medical Imaging and Radiation Sciences - Radiation Therapy

Radiation Therapy is the profession in which radiations are directed at diseased tissues in strictly controlled circumstances to cure or palliate the disease. The radiation therapist is in daily contact with the cancer patient, positioning them for treatment, performing mathematical calculations of radiation dosage, and operating a variety of equipment that produces ionizing radiation. Therapists may also specialize in treatment planning, which includes the design and construction of various treatment devices, manual and computerized dose computations, and dose measurement procedures. The radiation therapist has considerable responsibility in patient care and must be knowledgeable regarding the psychology of dealing with terminally ill patients and their families.

The Department of Medical Imaging & Radiation Sciences offers a four-year baccalaureate degree with programs in Radiography, Nuclear Medicine, Radiation Therapy, and Sonography. Students may apply to the professional phase of the program, which is offered at the University of Oklahoma Health Sciences Center in Oklahoma City, after completing 64 hours of general education, inclusive of the prerequisite courses.

Each of the four professional programs begins in the summer of every year and consists of 68 semester hours of sequenced and integrated didactic and clinical courses. Students will complete clinical assignments in selected hospital and clinic facilities located throughout the Oklahoma City metropolitan area. Program faculty determine student assignments to clinical rotation sites based upon each student’s abilities and clinical education needs.

Why should you choose a bachelor's degree program? Click here to learn more.  The four-year program culminates in the baccalaureate degree in Medical Imaging and Radiation Sciences (B.S.M.I.R.S.) in the specific discipline of study. Upon successfully completing the chosen educational program, the student is eligible to apply to the appropriate credentialing agency to sit for the certification examination in the respective profession.

In 1970, the department established a baccalaureate degree program in Radiography. Baccalaureate programs in Nuclear Medicine and Radiation Therapy were instituted in 1975. In 1978, the fourth program in Sonography was approved. The offering of baccalaureate degrees in all four disciplines within one academic department is unique in the country.

None of the four professions is a prerequisite to one another or subordinate to another. Each degree program can be entered directly after completing prerequisite courses and selection by the Admissions Committee through a competitive application process.

Course numbers are those of the University of Oklahoma.  Approved prerequisite courses are offered at many institutions.  It is extremely important that you look up every course you have taken, plan to take, and/or are currently enrolled in to verify that they are equivalent courses. The responsibility is yours to enroll in equivalent courses and we provide the tools to make sure you do. Check the Transfer Equivalencies Database or with your school advisor regarding equivalent courses.  There are instructions on that page on how to request a transcript evaluation for particular courses if your courses are not listed in the database.

Conditionally accepted applicants to the College of Allied Health in the Department of Medical Imaging and Radiation Sciences will be required to obtain a Criminal History Background Check and a Drug Test.  Conditionally accepted applicants who have an adverse finding on a criminal background report and/or drug test may be denied full admission. Many clinical facilities require a background check, including a check of the sex offenders list.  The student’s responsibility is to have the background check completed prior to starting the clinical experience and as instructed by the clinical coordinator. The student’s responsibility is to maintain the background check for presentation to the clinical facility personnel. 
Drug screening is required of all OUHSC students in designated programs as many clinical facilities require students to pass a drug test.  The student’s responsibility is to comply with the necessary procedures and consent forms for the required drug screening.  Students who fail to adhere to the drug testing procedure established by the Department will be deferred for a year while documentation can be received for clearance. 
Any arrest, charge, or conviction for a felony or a misdemeanor may also affect a graduate’s ability to sit for the certification examination in their profession.  For a fee, many certification boards will conduct a pre-assessment based on the student’s prior offenses to determine if the student would be allowed to sit for the board examination.  

Students may contact the following certification board directly for further information:

Course Descriptions

In accordance with Departmental and Programmatic policies, students must earn a C or above in coursework in order to maintain status within the program.

For most coursework, a traditional grading scale is utilized:
•    A = 90% and above
•    B = 80-89.4% 
•    C = 70-79.4% 
•    D = 60-69.4% 
•    F = below 60%

A higher standard is utilized for clinical course grading, as follows:
•    A = 92.5% and above
•    B = 85-92.4%
•    C = 75-89.4% 
•    D = 65-74.4%
•    F = below 65%

Within either system, only the final course grade will be rounded. All other grades will be carried out to the first decimal place. Faculty have autonomy for determining the rounding of grades within this general structure (e.g., 89.45 rounding up to an A, versus 89.5 required in order to round), and this information is presented in each course syllabus. 

There is a separate Zero Grade policy related to academic or clinical performance, which may impact student grades through deficiencies in performance. See section 2.7 of the MIRS Student Handbook, available here
