100% first time pass rate

Tracy, LRT Program Director

“Our Medical Assisting Program celebrated a 100% first time pass rate using the Control the Dose Limited Radiography Course and Test Prep System in combination with onsite labs and offsite practicum rotations.”

I took my Limited Scope Exam and passed with a 92%

Nathan from Washington

“I wanted to give you an update on how I did after using your test prep system. I took my Limited Scope Exam and passed with a 92%. I definitely would encourage other students to use this system! I would encourage you to use this as a study guide and not just to remember the questions. Know the material, use this test prep system, and anyone will do great. Thanks again, Nathan, WA”

Such a great learning tool!

William from Illinois

“The Limited Radiography Course offered by Control the Dose is an excellent course of study for those wishing to become familiar with basic diagnostic x-ray procedures. I found that the course syllabus was well organized and contained very useful and informative exercises. The mix of practical exercises, textbook readings, and clinical assignments was well balanced and reinforced the objectives. The combination of syllabus, textbook, and AV content makes this course both challenging and enjoyable. It is one of the most professional, well organized, and informative courses available today. It enabled me to take and complete the ARRT Limited Radiographer certification examination and pass with a 95%. Many thanks to Control the Dose for offering such a great learning tool!”

  • Who is the course for?

    The Control the Dose course provides a complete digital delivery of resources for those who need to operate x-ray equipment in a limited capacity. Our typical student has a license or experience in some other allied health area and is seeking a second license or skill at the request of his/her employer.

  • What is covered in the course?

    This course provides instruction in the limited use of ionizing radiation for diagnosis in medical and chiropractic offices, clinics, and smaller or rural hospitals. A Limited Radiographer produces routine images of the chest, extremities, spine and sometimes of the skull and/or sinuses. They typically provide health care along with a physician, chiropractor, physician assistant, nurse practitioner, radiologic technologists (RT), and or other limited radiographers.

  • Do you offer group discounts?

    The purchase of a Control the Dose Limited Radiography Course permits ONE student to have an account and instructor support. For group discounts contact us @ 402-904-8672

  • Do I qualify to take this course?

    The Course provides specific instruction in the use of x-rays in performing images as described above. We assume the student is licensed, certified, and/or experienced in health care and understands the basics of providing patient care. If this doesn’t describe your background, then your employer/supervisor will need to agree to provide that knowledge and those skills.

  • Who can be my supervisor?

    The qualifications for the supervisor vary by state. Typically the supervisor isa fully certified radiographer, R.T., a physician or chiropractor. Some states permit a physician assistant or a licensed limited radiographer to supervise as well.

  • Will I be considered proficient after taking this course and passing the exam?

    A Limited Radiographer must work towards increasing proficiency with every procedure and, in many states, participate in continuing education.
