Start

The clearest difference between a physical therapy technician and a radiology technician is regulatory: a physical therapy technician is an unlicensed support role you can enter with a high school diploma and short-term training, while a radiology technician is a licensed allied-health professional who must complete an accredited associate degree, pass the ARRT certification exam, and hold a state license in most states. That regulatory gap drives the wage gap. According to BLS May 2024 data, physical therapist aides earn a median annual wage of $34,520, while radiologic technologists and technicians earn $77,660. The training timelines reflect the same gap: physical therapy technician programs run from a few weeks to several months, and radiology technician programs typically take 18 to 24 months plus clinical hours.

Key Points

A physical therapy technician (also called a physical therapy aide) assists physical therapists with patient setup, equipment, and non-clinical tasks under direct supervision.
A radiology technician operates imaging equipment such as X-ray, CT, and MRI machines to produce diagnostic images for physicians.
Median annual wages are $34,520 for physical therapist aides and $77,660 for radiologic technologists and technicians (BLS, May 2024).
Employment of physical therapist aides is projected to grow 3% from 2024 to 2034, and radiologic technologists and technicians 4% over the same period (BLS).
Physical therapy technicians work in an unlicensed support role nationwide, while radiology technicians typically need ARRT certification and state licensure to practice.

What Is a Physical Therapy Technician?

A physical therapy technician, also called a physical therapy aide, is an unlicensed healthcare support worker who assists physical therapists and physical therapist assistants in clinics, hospitals, and rehabilitation centers. The role is non-clinical and limited to tasks that do not involve direct treatment.

Typical day-to-day duties include:

Preparing treatment rooms and equipment before patient sessions
Cleaning and sanitizing therapy equipment between patients
Helping patients move between waiting areas, treatment tables, and exercise stations
Applying hot and cold packs as directed by the supervising therapist
Handling clerical tasks like appointment scheduling and patient intake forms
Restocking supplies and maintaining the treatment area

Physical therapy technicians do not design treatment plans, administer therapeutic exercises independently, or evaluate patient progress. Those functions are reserved for licensed physical therapists and physical therapist assistants. Most physical therapy technicians enter the field with a high school diploma plus on-the-job training, though short certificate programs can strengthen a job application.

What Is a Radiology Technician?

A radiology technician, also called a radiologic technologist or radiographer, is a licensed allied-health professional who performs diagnostic imaging procedures using X-ray, computed tomography (CT), magnetic resonance imaging (MRI), and fluoroscopy equipment. The role is clinical and requires technical competency in radiation safety, patient positioning, and image quality.

Typical day-to-day duties include:

Reviewing physician orders and confirming the appropriate imaging procedure
Positioning patients accurately to capture the requested anatomical view
Operating and calibrating imaging equipment, including digital radiography and CT scanners
Following ALARA (As Low As Reasonably Achievable) protocols to limit radiation exposure
Administering contrast agents under physician direction when needed
Maintaining patient records and routing images to radiologists for interpretation
Assisting with fluoroscopy, mobile imaging, and operating-room procedures

Radiology technicians work closely with radiologists, who are physicians (MDs) trained to interpret the images. The technician produces the image; the radiologist diagnoses from it. Entry into the field requires graduation from a JRCERT-accredited program, ARRT certification, and a state license in most states.

Training and Certification Requirements

The training pathways differ sharply, which is the practical expression of the entry-barrier gap between the two careers.

Physical Therapy Technician Training

A physical therapy technician needs a high school diploma or equivalent as the baseline. Formal training is optional but increasingly common; certificate programs typically run from one to six months and cover anatomy, medical terminology, common rehabilitation modalities, body mechanics, patient safety, and clinic operations.

There is no national licensing exam for physical therapy technicians. Some certificate programs prepare graduates for voluntary credentials such as the Physical Therapy Technician/Aide Certification (PTTC) from the American Medical Certification Association (AMCA), but no state requires a physical therapy aide to hold a credential to work. State practice acts regulate what physical therapy aides can and cannot do under physical therapist supervision, but the regulation applies to the supervising therapist's scope, not to the aide directly.

Programs available through Dreambound include short online certificates from Penn Foster which prepare students for entry-level physical therapy aide roles and include optional certification prep.

Radiology Technician Training

A radiology technician needs an Associate of Applied Science (AAS) degree from a program accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT). Full-time programs run 18 to 24 months and combine classroom instruction in anatomy, radiographic positioning, radiation physics, and patient care with hundreds of hours of supervised clinical rotations.

After graduation, candidates apply to the American Registry of Radiologic Technologists (ARRT) and sit for the Radiography certification exam, a 200-question multiple-choice assessment administered at Pearson VUE testing centers. Passing the exam earns the R.T.(R)(ARRT) credential, which more than 75% of states require for state licensure.

State licensure adds a separate step in most states. California issues the Certified Radiologic Technologist credential through the Radiologic Health Branch. Texas requires ARRT certification plus a jurisprudence exam. New York charges a $120 license fee with four-year renewals requiring 48 continuing education hours. Georgia, Alabama, and Washington D.C. do not require state licensure for radiography, though employers in those states still require ARRT certification.

Fully online radiology technician programs are not possible: ARRT requires hundreds of in-person clinical hours, and coursework that involves positioning patients or operating radiation equipment cannot be completed remotely. Hybrid programs that deliver didactic content online and place students at local clinical sites are common, including limited-scope options like the CCI Training Center program offered through Dreambound.

Salary and Job Outlook

The wage gap between the two careers reflects the credentialing gap. Both occupations show growth at or just above the average for all occupations.

Physical Therapy Technician Salary

BLS May 2024 data lists the median annual wage for physical therapist aides at $34,520. The lowest 10% of physical therapist aides earned less than $24,960, and the highest 10% earned more than $46,930.

The highest-paying state for physical therapist aides is Minnesota, where the annual median wage is $44,340.

BLS projects employment of physical therapist aides to grow 3% from 2024 to 2034, about the same as the average for all occupations. Demand is tied to the broader expansion of physical therapy services for an aging population, which is driving stronger growth on the physical therapist assistant side of the occupation.

Radiology Technician Salary

Radiologic technologists and technicians earn a median annual wage of $77,660 according to BLS May 2024 data. The figure includes both technologists and technicians working across X-ray, CT, and related modalities.

The highest-paying states for radiologic technologists and technicians are California at $107,670 and Massachusetts at $99,910. Both reflect a combination of state wage floors and concentrated demand in large metropolitan hospital systems.

BLS projects employment of radiologic technologists and technicians to grow 4% from 2024 to 2034, faster than the average for all occupations. Growth is driven by an aging population, rising chronic disease prevalence, and expanded use of diagnostic imaging in outpatient settings.

If these training timelines and salary ranges fit your goals, you can compare physical therapy technician and radiology technician programs side by side on Dreambound by format, length, and location.

Role Overlap and State Licensing Differences

The two roles do not overlap in practice. A physical therapy technician cannot perform imaging procedures, and a radiology technician cannot deliver physical therapy treatment. Both are restricted to their own scope of practice, and crossing into the other field requires the credentials specific to that field.

The state licensing reality is also different:

Physical therapy technicians are unlicensed in every state. State practice acts regulate physical therapy itself, and aides work under the supervising therapist's license. No state administers a physical therapy aide licensure exam or maintains a physical therapy aide registry.
Radiology technicians are licensed in most states. The American Society of Radiologic Technologists tracks roughly 41 states plus federal jurisdictions that require licensure for radiography practice. Each state sets its own application, fee, and continuing education requirements. ARRT certification is the most common gateway, but it is not a substitute for the state credential.

This distinction matters when comparing relocation flexibility. A physical therapy technician trained in one state can typically begin work in another state without a credentialing process. A radiology technician relocating between states often needs to apply for a new state license even when ARRT certification carries over.

Which Program Is the Right Fit for You?

A direct comparison of fit:

A physical therapy technician may be the stronger fit if:

You want to enter healthcare in months rather than years
You prefer hands-on patient interaction and rehabilitation over diagnostic procedures
You are not ready to commit to a 2-year associate degree
You are testing whether healthcare suits you before a longer training investment
You plan to use the role as a stepping stone toward a physical therapist assistant or physical therapist career

A radiology technician may be the stronger fit if:

Frequently Asked Questions

Which career is the better fit, physical therapy technician or radiology technician?

It depends on how much training you want to complete before starting work and what kind of patient interaction you prefer. Physical therapy technician is a faster, unlicensed entry point with hands-on rehabilitation work and lower starting wages. Radiology technician requires an accredited associate degree, ARRT certification, and state licensure in most states, but it leads to a higher-paid technical career in diagnostic imaging. The credentialing commitment is the central decision point.

Can you switch from physical therapy technician to radiology technician later?

Yes, but there is no shortcut. Switching requires completing a JRCERT-accredited radiography program (typically a 2-year associate degree), passing the ARRT certification exam, and obtaining state licensure. Prior experience as a physical therapy technician can strengthen a radiography program application through familiarity with patient care, medical terminology, and clinical environments, but it does not reduce the program length or substitute for accredited coursework. If you are considering the switch, you can compare radiology technician programs on Dreambound by length and certification path.

What is the difference between a radiology technician and a radiologist?

A radiology technician is an allied-health professional with an associate degree and ARRT certification who operates imaging equipment and produces diagnostic images. A radiologist is a physician (MD or DO) who completes medical school, a four-year radiology residency, and often a subspecialty fellowship to interpret those images and make diagnoses. The technician captures the image; the radiologist reads it and writes the diagnostic report.

What is the difference between a physical therapy aide and a physical therapy technician?

The two terms refer to the same role. "Physical therapist aide" is the title BLS uses in its Occupational Outlook Handbook and Occupational Employment and Wage Statistics survey. "Physical therapy technician" is the common job-posting and program title used by employers and training providers. Both describe an unlicensed support role assisting physical therapists with non-clinical tasks under direct supervision.

Does every state require radiology technicians to be licensed?

No. Roughly 41 states plus federal jurisdictions require state licensure for radiography practice, but states including Georgia, Alabama, and Washington D.C. do not require a separate state license. In those states, ARRT certification alone is generally enough to work, though individual employers may still set additional requirements. Always confirm current rules with the state's radiation control program or radiologic technology board before beginning training in a state you plan to work in.

Choosing Between a Physical Therapy Technician and a Radiology Technician Career

The decision comes down to one question: how much credentialing are you willing to complete before you start working? A physical therapy technician role is reachable in weeks with a high school diploma, places you in direct rehabilitation work, and pays a median wage of $34,520. A radiology technician career requires 18 to 24 months of accredited training, an ARRT exam, and a state license in most states, but it leads to a median wage of $77,660 and a technical role with clear advancement paths into CT, MRI, and mammography.

Neither career is better in the abstract. They are different commitments leading to different work. The physical therapy technician path makes sense for someone testing healthcare or wanting fast entry; the radiology technician path makes sense for someone ready to invest in licensure for higher pay and clinical responsibility. Compare physical therapy technician and radiology technician programs on Dreambound by format, length, and certification path to see which one matches the commitment you can make.
