CT Therapy Certificate (CTRT)

Improvements in digital technology have allowed for the use of CT in the practice of radiation therapy to more accurately plan and individualize treatment for each patient. Use of CT has allowed for more accurate treatment simulation, treatment planning and treatment delivery.

The success of cancer treatment is dependent on the accuracy and the quality of the design and delivery of the radiation beam. Use of CT improves targeting of the cancer and the avoidance of unnecessary irradiation to normal tissue.

Purpose of the Program

The intent of the CTRT Certificate program is to provide a mechanism for radiation therapists to demonstrate knowledge and competence in the use of CT, promote standards of excellence within this clinical area, and to identify those who have met a nationally recognized standard.

Program Overview

The following is an overview of the CT Therapy Certificate program. For detailed information, download the CTRT Handbook.

There are two components of the CTRT Certificate program: didactic and clinical*.

*The clinical component is available to registered candidates only.

Didactic Component
Clinical Component

Clinical Advisor

The clinical component requires the candidate to identify a Clinical Advisor.

The clinical advisor must:

  • Be a radiation therapist with a CTRT credential or have a minimum of 5 years’ experience in the practice of radiation therapy in the CT SIM
  • Not be currently registered in the CTRT program
  • Identify others delegated to assess the candidate and ensure they are credentialed and competent in their practice
  • Perform the assessment on the candidate for all procedures/associated competencies or delegate assessment to another therapist or credentialed health care provider (such as a physicist, RN, BSc N or Medical Doctor)
  • Attest to the overall competency of the candidate by singing at the end of each Module.


Candidates in the CTRT Certificate program must complete both the didactic and clinical components within a five-year timeframe. This timeframe begins on the date of successful completion of the first CT course used toward the CTRT Certificate program.


As of January 2016, the CAMRT has changed the name and credential associated with the CTIC – Radiation Therapy Program. This program is now called the CT Therapy Certificate Program and the credential given for completion of the program has changed from CTIC (RT) to CTRT.

Candidates who successfully complete the didactic and clinical components as per the CTRT Certificate program requirements receive a CT Therapy Certificate and can use the credential “CTRT”.

The Committee strongly advocates for continued competence through continuing professional development.
