Radiologic Sciences



Radiologic Sciences is a comprehensive term applied to the science of administering radiation, ultrasound or magnetism to provide information for the diagnosis and treatment of diseases and injuries. 

Bachelor of Science in Radiologic Sciences, Initial Certification

For individuals seeking entry into the radiologic sciences profession, we offer an entry-level bachelor of science degree with special emphasis leading to certification in one of five career specialties. No previous background in the radiologic sciences is required to enter any of these programs. Graduates are eligible to sit for the national certification examination in their specific area of specialty (see Certification section below for additional details). All students in the department will do some level of online coursework. Typically, students in entry-level tracks take five to ten online courses over the five semesters.


Radiographers use radiation, magnetism, and computers in the production of medical images that aid the physician in the diagnosis of broken bones, ulcers, tumors, diseases, or malfunctions of various organs.

Radiation Therapy

Radiation Therapists deliver daily radiation treatments to cancer patients to ensure the treatments are accurately and safely administered

Nuclear Medicine

Nuclear Medicine is a specialty in which radioactive pharmaceuticals are used to diagnose or treat disease.


Sonography is used to image organs, blood vessels, and the fetus. Sonographers use equipment that emits sound waves into the body and the echos sent back are converted to images.


Cardiovascular/Interventional Program will prepare individuals to assist in invasive cardiovascular settings in cardiac catheterization departments, electrophysiology laboratories, and angiography departments

RT to BS Degree Completion

Our degree completion programs offer certified professionals a path to complete a bachelor's degree and develop additional professional practice skills and technical skills in radiation therapy or an advanced radiography area (CT, MRI, or mammography) .

Bridge Program

Professionals already registered in radiography, radiation therapy, nuclear medicine, or sonography can earn a bachelor's degree emphasizing your current discipline. The program offers fully online clinical and non-clinical tracks and a partially online management track. 

Special Options Program

Professionals already registered or registry-eligible in radiography, nuclear medicine, or radiation therapy receive training leading to certification in another of these specialties while earning a bachelor's degree.

Post-Baccalaureate Certificate

If you already have a bachelor's degree in radiologic technology, radiologic sciences, or a related area, this fully online post-baccalaureate certificate program will prepare you for advanced practice in computed tomography, magnetic resonance imaging or mammography.


Upon graduation from Armstrong, Radiography, Radiation Therapy, and Nuclear Medicine students will be eligible to sit for the national certification examination of the American Registry of Radiologic Technologists (ARRT). Nuclear medicine students are also eligible to sit for the Nuclear Medicine Technology Certification Board (NMTCB). Sonography students will be candidates for the national certification examination of the American Registry for Diagnostic Medical Sonographers (ARDMS). Cardiovascular Interventional Sciences students will take the Registered Cardiovascular Interventional Specialist Examination administered by Cardiovascular Credentialing International (CCI)
