Radiation therapy is the treatment of cancer and other diseases using radiation. In high doses, radiation kills cells or keeps them from growing and dividing. Because cancer cells grow and divide more rapidly than most of the normal cells around them, radiation therapy can successfully treat many kinds of cancer.
Radiation Therapy can be delivered in different ways. External beam radiotherapy uses machines to focus radiation on a cancer site. Depending on the radiation beam energy, it can be used to destroy cancer cells both on the surface and deeper in the body. The higher the energy of the beam, the deeper the radiation can penetrate into the target tissue.
Internal radiotherapy, or brachytherapy, places radioactive implants directly in a tumour or body cavity. In this treatment, the radiation dose is concentrated in a small very area.
What does a Radiation Therapist do?
Working closely with doctors, medical physicists, patients and other members of the health care team, Radiation Therapists navigate highly technical equipment while delivering empathetic and patient-centered care. Radiation Therapists use advanced computer systems and radiation therapy equipment to design and implement treatment plans and deliver radiation treatment, including:
- Planning all treatment details, including calculating the radiation dose and simulating its distribution
- Positioning the patient and operating the radiation therapy equipment
- Constructing and fitting accessory devices that shape, modify and direct the radiation to destroy cancerous tissue
- Therapists also play an important role in counseling patients on possible side effects from treatments and provide advice on how best to minimize these effects. Because radiation treatments often extend over several weeks, a special supportive relationship often develops between the therapist, the patient and the patient’s family.
Is Radiation Therapy a good choice for you?
Radiation Therapists are detail-oriented and enjoy applying their knowledge of biology, mathematics and physics, since their work requires precision and the safe operation of sophisticated equipment. In addition to employing technical expertise in computerized systems used to for the simulation and planning of treatment details, Radiation Therapists provide the patient and their family with in-depth and continuous care, support, and counseling throughout the treatment process. Although future career opportunities may take you into other work environments, Radiation Therapists are typically employed in Cancer Centres and work with their patients during scheduled appointments over weeks or several months.
Future career opportunities as a Radiation Therapist include research activities, advanced roles such as the clinical specialist radiation therapist (CSRT), management, education, sales/marketing, other specialties such as magnetic resonance imaging (MRI) and computed tomography (CT), higher education at a master’s level, and working abroad.
Graduates of the Radiation Therapy stream of the MRS program will earn a BSc in Medical Radiation Sciences from the University of Toronto and an Advanced Diploma in Health Sciences (Radiation Therapy) from The Michener Institute. MRS graduates are eligible to write the national certification exam offered by the Canadian Association of Medical Radiation Technologists (CAMRT) and may pursue advanced studies at U of T or Michener, such as:
- Magnetic Resonance Imaging (MRI)
- Master of Applied Science (Institute of Medical Sciences)
- Master of Health Administration

Learners will develop an understanding of what it means to be a medical radiation technologist, a healthcare professional, and interprofessional collaboration. As well, learners will be exposed through a series of seminars delivered by healthcare professionals from the practice setting, to a variety of imaging modalities used in the diagnosis and treatment of patients. Modalities such as X-ray, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Ultrasound (US), Positron Emission Tomography (PET), and Image Guidance for Radiation Therapy will be explored. Additional topics relating to the imaging modalities will be covered including Informatics, Artificial Intelligence/Machine Learning and Interventional Radiology.
Patient Care in Medical Radiation Sciences I (PMRS111/MRS227H1)
Examining a variety of fundamental patient care topics using a patient-centred lens, learners will be introduced to the professional, ethical, and legal standards which will be reinforced throughout the Medical Radiation Sciences (MRS) curriculum. Patient care skills will be enhanced through the study of communication, medical terminology, infection control, clinical assessment techniques and relevant pharmacology, including contrast media. This course will also provide the opportunity to develop communication and care-delivery strategies for diverse patient populations. Reflective practice will be introduced and developed throughout the course as learners work towards becoming reflective practitioners.
Introduction to Clinical Oncology (ONRT120/MRS144H1)
This course provides the learner with an understanding of the basic concepts of oncology, including epidemiology and etiology, natural history, clinical signs and symptoms, routes of spread, pathology, staging systems and management approaches. Topics covered also include diagnostic and staging workup, prognostic factors, decision-making skills for treatment options, and principles of treatment.
Radiobiology & Radiation Protection (RBRT310/MRS143H1)
Aspects of the physics and chemistry of ionizing radiation will be discussed. The cellular and molecular effects of ionizing radiation and how they help in the understanding and current practice of radiation therapy will form the major emphasis of the course. Sources of data on the effects of human exposures to ionizing radiation will be described. As well, there will be a description of a typical radiation protection program at a radiation therapy facility.
Introduction to Radiation Physics (RSRT310/MRS142H1)
This course examines the different types of radiation and how they interact with matter. Pertinent properties of both the radiation and the materials that dictate the nature of the interaction are discussed. A review of the structure of matter also reveals the physical origin of radiation production in relation to both external radiation therapy and brachytherapy.
YEAR 1 WINTER – SEMESTER 2
Relational Anatomy (ANRD121/MRS164H1)
This Relational Anatomy course requires learners to apply their knowledge of gross anatomy to explore the cross-sectional and relational anatomy of the head, central nervous system, neck, spine, thorax, abdomen, pelvis (male/female) and the upper and lower extremities. An emphasis is placed on the learner’s ability to identify and justify the relative positions of the organs, the vascular system, the lymphatic system as well as muscular and skeletal structures in each of the aforementioned anatomic regions.
This course will introduce students to the function of the organ systems that comprise the human body. The course will follow a systematic structure covering all of the principal functional systems within the body, examples include the cardiovascular and respiratory systems. Learners are expected to be familiar with the anatomical structure of these systems.
