A limited x-ray tech is a healthcare professional who takes diagnostic X-ray images but only of specific body parts, not the full range of imaging a fully licensed radiologic technologist handles. The formal term used by the American Society of Radiologic Technologists is “limited x-ray machine operator,” or LXMO, though you’ll also see titles like limited medical radiologic technologist (LMRT), limited permittee, or simply x-ray technician depending on the state. It’s one of the faster entry points into medical imaging, with training programs that can be completed in as little as 8 to 12 months.
What a Limited X-Ray Tech Can and Can’t Do
The key word is “limited.” A limited x-ray tech is authorized to image only certain anatomical areas. The specific list varies by state, but the ARRT exam and national curriculum cover five procedure categories: chest, extremities (arms, hands, legs, feet), skull and sinuses, spine, and podiatric imaging. Within those categories, the work is detailed. An extremities-certified tech, for example, would image everything from individual fingers and toes to shoulders, knees, and elbows.
What’s off the table is just as important. Limited x-ray techs do not perform fluoroscopy, CT scans, MRIs, mammography, or any procedure that requires injecting contrast agents. Those advanced modalities require a full radiologic technologist credential or specialty certification. If a facility needs only standard X-rays, though, a limited tech can handle the job independently.
Where Limited X-Ray Techs Work
Urgent care clinics are the single biggest employer for this role. Since urgent care relies almost exclusively on basic X-ray and doesn’t need CT, MRI, or other advanced imaging, a limited tech fills the need without the higher salary a full radiologic technologist commands. Orthopedic offices, chiropractic clinics, podiatry practices, primary care offices, and small rural clinics also hire limited techs for the same reason: their imaging needs are straightforward and high-volume.
Hospitals, freestanding imaging centers, and outpatient surgery centers generally require full radiologic technologists because those settings use a broader range of imaging equipment and procedures.
Training and Education
Limited x-ray tech programs are certificate programs, not degree programs. Most take between 8 months and about 14 months to complete. A typical structure splits time between classroom learning (often available online with live lectures and lab simulations) and a clinical externship at a medical facility. At CCI Training Center, for instance, students spend roughly four months in coursework and four months in hands-on clinical rotations.
Compare that to a full radiologic technologist, who earns an associate degree over roughly two years of more intensive coursework and clinical hours. Some schools offer a bridge pathway: complete the limited tech certificate first, work in the field, then return for an associate degree completion program that takes an additional 60 to 64 weeks. This route lets you start earning sooner while keeping the door open to advance later.
Certification and Licensing
The ARRT administers the national Limited Scope of Practice in Radiography exam. It has two parts: a core module that every candidate takes, covering radiation safety, equipment operation, and patient care fundamentals, plus one or more procedure modules based on the body areas you want to be certified in (chest, extremities, skull/sinuses, spine, or podiatric).
Licensing requirements vary significantly by state. Some states require you to pass the ARRT limited scope exam. Others have their own state-specific exams. A few states don’t regulate limited x-ray operators at all. You’ll need to check with your state’s radiation control or health department to find out exactly what’s required where you plan to work. Once credentialed, most techs need to complete 24 approved continuing education credits every two years to stay current.
Salary Expectations
The Bureau of Labor Statistics does not track limited x-ray techs as a separate category, which makes pinning down an exact median salary difficult. The broader category of radiologic technologists and technicians had a median annual wage of $77,660 as of May 2024, with the lowest 10% earning under $52,360 and the highest 10% earning above $106,990. Limited scope techs fall toward the lower end of that range because of their narrower scope of practice and shorter training. Job postings and salary aggregators typically place LXMO/LMRT wages between $35,000 and $55,000 annually, though this swings depending on your state, employer type, and how many procedure modules you’re certified in.
Full radiologic technologists generally out-earn limited techs because they can take on more complex procedures, work in higher-paying hospital settings, and pursue specialty certifications in CT, MRI, or mammography that push salaries higher.
Limited Tech vs. Radiologic Technologist
The practical differences come down to three things: time in school, what you’re allowed to image, and where you can work.
- Education: A limited tech certificate takes roughly 8 to 14 months. A radiologic technologist associate degree takes about two years.
- Scope of practice: Limited techs perform standard X-rays on approved body areas only. Full RTs perform a wider range of X-ray procedures and can pursue advanced modalities like CT, MRI, fluoroscopy, and mammography.
- Work settings: Limited techs are well suited to urgent care, outpatient clinics, and specialty offices. Full RTs have access to those settings plus hospitals, imaging centers, and surgical facilities.
- Earning potential: RTs typically earn more due to their broader scope, and they have more pathways to specialize into higher-paying roles over time.
For someone who wants to start working in healthcare quickly and doesn’t mind a focused scope, the limited tech route makes practical sense. Many people use it as a stepping stone, gaining clinical experience and income while deciding whether to pursue the full radiologic technology degree later.
