Certificate in Computed Tomography

About Computed Tomography

If caring is your calling and you are currently working as a radiologic technologist and want to increase your marketability and earning potential with additional skills or certifications, Parker University’s Computed Tomography (CT Scan) Certificate Program is for you.

CT didactic courses are offered online, in just one semester allowing you to complete this program around your current work schedule. Students in this program will make their own clinical arrangements to fulfill the ARRT clinical requirements.

Upon completion, technologists will receive the coursework and obtain clinical training to be awarded the Certificate in Computed Tomography from Parker University and qualify to take the Advanced Certification Examination in Computed Tomography offered by the American Registry of Radiologic Technologists (ARRT).

Program PDF Fact Sheet

Program Description

Computed Tomography is an advanced radiographic imaging modality that utilizes highly collimated fan-shaped x-ray beam and array of radiation detectors to produce cross-sectional images of human body structures and organs needed by physicians for diagnostic purposes. Computed tomographic images can be reconstructed in various anatomical orientations to demonstrate image details that allow for better visualization of pathology, diagnostic analysis, and radiologic interpretations.

About the Program

Course work in cross sectional anatomy, pathology, patient care and safety, CT procedures, equipment, image evaluation, instrumentation, image pathology, technique, physics, quality assurance, and quality control.  Student must maintain a C or better in all CT Program courses. Any CT Program courses needing to be repeated due to withdrawal, failure, or grade less than a C requires the student to repeat the failed course at the next offering.

Note: the ARRT requirements for both the structured education requirements and the clinical experience requirements must not be more than 24 months old at the time of application for the ARRT Computed Tomography Examination.

It is recommended that candidates keep a personal copy of exams performed. Since the application is filled out online, the student is audited as they progress through the exams. Once all the exam requirements have been met, the chart on the “Pursue Post-Primary Certification and Registration” page will be updated to reflect the candidate’s status. Once 100% progress has been accomplished, the application form can be completed.

Clinical Education Requirements

The purpose of clinical training is to provide students with the necessary practical skills that will ensure they master competencies in those procedures required by the ARRT.  Procedure competency is continually evaluated by the instructors and qualified technical staff at the facility you choose to obtain your competencies.  Skills must be completed before the CT Certificate can be given.

The Clinical Experience Requirements for CT consist of 59 procedures within the 8 following categories:

Head and neck
Spine and musculoskeletal
Abdomen and pelvis
Special procedures
Image display and post processing
Quality assurance

Candidates must document complete diagnostic quality procedures according to the following rules:

  • Choose a minimum of 25 different procedures out of the 59 in 8 different categories.
  • Complete and document a minimum of 3 and a maximum of 5 repetitions of the chosen procedures (Less than 3 will not be counted)
  • A minimum total of 125 repetitions across all procedures must be documented
  • No more than one procedure may be documented on one patient.

Students are expected to initiate and investigate new and more advanced learning opportunities, as those opportunities present themselves.  Common, yet unplanned, opportunities for learning such as cardiac arrests, major trauma and rare conditions and diseases cannot by their nature be a planned part of clinical education.  Therefore, the student should take the initiative to become engaged in those activities as they present themselves.

Document Performance

Candidates must use the My ARRT info link (https://www.arrt.org/) within the ARRT website to record the performance of the procedures. Documentation includes: name of procedure, date performed, time of day completed, facility where performed, and the name of the person verifying performance. Exams should be recorded online as they are performed. The “Verifier’s Name” column on the form must correspond to the technologists’ email address provided by the candidate. The technologist will be sent an email, from the ARRT, for each exam they supervise. The tech must accept the exam for it to count towards your repetitions. **All procedures must be performed within the 24 month period immediately preceding the date of the candidate’s signature on the application for certification. Repetitions may be completed in less than 24 months. Failure to meet the minimum clinical experience requirements prior to the date of the application signature will result in the application becoming “ineligible.” All documented procedures prior to that application date will not be accepted for future clinical experience requirements.


*Students will be allowed to complete the competencies required within a 6 month window from the beginning of the CT certificate program.

**Students will then have a 24 month window set by the ARRT to take the CT registry.
