Important Reminders

  • Limited Scope X-ray Operators must not operate fluoroscopy, computed tomography (CT), cone beam computed tomography (CBCT), mammography or perform x-ray procedures where contrast media is used.
  • Individuals not Licensed Practitioners of the Healing Arts who want to take x-rays on humans in Minnesota and are not already certified to do so, must pass the American Registry of Radiological Technologists (ARRT) Limited Scope X-ray Operator Exam, as specified in Minnesota Rules, Chapters 4732.0570 to 4732.0585.
  • Those who passed the Minnesota X-ray Operator Exam on or prior to Jan. 1, 2008 are grandfathered in and do not have to take this exam. If you need proof of certification, MDH does not have a copy. Please contact your school, previous employer, or the appropriate test provider.
  • Limited Scope X-ray Operator applicants must pass the Core Exam and the respective region of anatomy module exam(s) before performing x-rays. You must pass the Core Exam before taking x-rays on any passed modules.
  • If an applicant fails a module, they will need to retake and pass in order to take x-rays of that anatomical region.
  • The fees and registration application process is the same for the initial registration application and the retake registration application. Once a module or exam is passed, it does not have to be retaken.
