Computed Tomography (CTI)

Medical machine

Department: Medical Imaging

Program Type: Health Professions


Computed Tomography (CTI) technologists are highly trained radiographers who work with special rotating X-ray equipment to obtain "slices" of anatomy at different levels within the body. CT technologists are essential to the medical imaging team, performing scans and diagnosing various injuries and diseases. In this role, you'll produce cross-sectional radiologic images of internal organs to be evaluated by physicians. CT techs are the primary liaison between patients, radiologists, and other support team members. Their additional training can lead to increased salaries in various health care settings.

CT Technologist Program Entrance Requirements

To become a CT scan tech in the health care industry, you must graduate from an accredited Medical Imaging Program such as the one at Elgin Community College. You'll need to be certified by the American Registry of Radiologic Technologists (ARRT) and have a special additional certification to work specifically with CT machines and ARRT certification on CT within one year of hire. As with other jobs in this field, you will also need Illinois Emergency Management Agency (IEMA) licensure.

Prepare for Immediate Employment

The future employment outlook for Computed Tomography is positive. This growth is attributed to an aging population and advances in technology that allow for more detailed and accurate imaging. Additionally, as healthcare technology continues to advance, the demand for CT scans is expected to increase. This in turn will lead to more job opportunities for CT technologists.

The median salary for a CT technician in the U.S. is about $64,000. Average pay ranges between $47,000 and $91,000 depending on experience level and location. Refer to Career Coach for more information regarding similar occupations and compensation.

What is Computed Tomography?

The term “computed tomography,” or CT, refers to computerized X-ray imaging where a narrow beam is rotated around the body that generates cross-sectional images, or “slices,” called tomographic images, which give more detailed information than conventional X-rays. Successive slices are digitally “stacked” to form a three-dimensional (3D) image to easily identify structures, tumors, and abnormalities.

A computed tomography scan (abbreviated to CT scan, formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. People who perform CT scans are called radiographers or radiology technologists.

CT scanners use a rotating X-ray tube and a row of detectors to measure X-ray tissue variance inside the body. A CT scan can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is prohibited.

What do CT Technologists do?

  • Operate head or body X-ray scanners that create a computer-generated cross-sectional image, commonly called a CAT (Computed Axial Tomography) Scan.
  • Responsible for educating and preparing patients for their examinations.
  • Provide patient care that is essential to the performance of a variety of procedures.
  • Take the patient’s medical history before an exam.
  • Position patients so that desired anatomy will be demonstrated.
  • Determine and set appropriate technical parameters to demonstrate anatomy and pathology accurately.
  • Assume responsibility for the safety and mental and physical comfort of patients.

How do I become a CT Technologist?

The first step to becoming a CT technologist will be an associate degree from an accredited program in an area of study such as:

  • Radiography
  • Radiologic technology
  • Radiologic sciences
  • Nuclear medicine technology
  • Diagnostic medical sonography

CT technologists can pursue a bachelor’s degree in radiologic technology to increase job opportunities. After graduating from an accredited program and completing specific education in computed tomography, individuals must pass their CT Registry Exam, administered by the American Registry of Radiologic Technologists (ARRT). Most states accept certification from:

  • American Registry of Radiologic Technologists (ARRT)
  • Nuclear Medicine Technology Certification Board (NMTCB)

What sets ECC’s program apart?

ECC’s flexible online and evening curriculum allows students to complete the program full-time or part-time. Courses are offered in online or hybrid formats. You may also take courses to fulfill ARRT continuing education requirements for registered technologists.

The advanced certificate program graduates at ECC are highly skilled and qualify to sit for the advanced certification examination by the American Registry of Radiologic Technologists (ARRT).

How long does it take to become a CT Tech?

The program at ECC consists of two semesters, beginning in the fall semester and ending in the spring. Students may enroll part-time (two-year track) or full-time (one-year track) in the Computed Tomography Program.
