Information for patients on the profession
The diagnostic imaging department includes a range of staff who are there to support you with a quality service during your diagnostic procedure. For all diagnostic procedures you will be assisted by a diagnostic radiographer.
Diagnostic radiographers use a range of techniques to achieve a high quality diagnostic image which aids in the diagnosis of an injury or disease. An important aspect of their role is to provide this service in a safe, accurate and controlled manner so as to limit the radiation exposure risk to the patient.
The main focus of diagnostic radiography is to identify and monitor injuries, diseases and trauma. These services are provided 24 hours a day and use a variety of techniques to achieve this. They include:
- X-radiation (X-Rays) is used to examine bones for abnormalities. They can also examine the digestive system using live motion imaging (fluoroscopy) or the blood vessels by means of live motion angiography. These live imaging procedures require the use of contrast agents.
- Computed Tomography (CT) is a diagnostic tool which provides cross-sectional images of the body which can then be reconstructed using computer software to form a 3D image.
- Nuclear Medicine examines the function of the organs and the body by using of radioactive tracers which are injected prior to the scan.
Many diagnostic radiographers are also qualified and trained in diagnostic procedures which do not use radiation. These include:
- Ultrasound which uses high frequency sound to produce diagnostic images. This is an increasingly used technique in areas of obstetrics, gynaecology, abdominal, vascular and musculoskeletal cases.
- Magnetic Resonance Imaging (MRI) which provides cross-sectional images of the body. These can be reconstructed to 3D images.
General Radiotherapy Information for Patients
This is general radiotherapy information for patients and their families. It is important to know that Radiotherapy treatments vary from patient to patient even if your cancer is the same. Don’t hesitate to speak to a health professional directly linked to your treatment i.e. your consultant, nurse or radiation therapist if you require further information.

What is Radiotherapy?
Radiotherapy is the use of high energy x-rays used to treat cancer.
Most patients receiving radiotherapy will either receive external x-ray or electron beam treatments. Radiotherapy is like getting an x-ray and nothing is seen or felt during these treatments. A machine called a linear accelerator is used to administer the radiation treatment. Radiation is used more and more in medicine and the radiotherapy team is specifically qualified in this area.
Why is Radiotherapy needed?
Radiotherapy is very important in the management of cancer. Over 50% of patients receive radiotherapy at some point during the management of their cancer. Radiotherapy is a localised treatment to the cancer site killing the cancer cells but allows normal cells repair themselves generally. Radiotherapy can be given alone or in conjunction with other treatments to kill the cancer cells. These treatments include surgery, chemotherapy and hormone therapy. The medical team decide on the best course of treatment suited to the patient.
Radiotherapy can be given to help cure the disease (Radical treatment) or to alleviate symptoms (Palliative treatment) of the disease. The course of treatment can be different for a patient receiving radical radiotherapy treatment or palliative treatment.
Radical radiotherapy is used with the intent to kill the cancer cells and cure the disease. A course of radical radiotherapy treatment can be anything from 2 to 8 weeks Monday to Friday. These treatments administer a small dose of radiation a day to kill the cancer cells but to allow normal cells time to recover.
Palliative radiotherapy is used to alleviate symptoms of the cancer e.g. pain. When a cancer is no longer curable palliative radiotherapy maybe used. Lower doses of radiotherapy are given than for curative treatment, usually over a shorter period of time (sometimes just a single treatment).
Information for patients on the profession of a Radiation Therapist
A radiation therapist is a highly skilled health professional with an honours bachelor’s degree in radiation therapy. Specific knowledge on this course would include cancer medicine, anatomy, physiology, radiation protection and medical physics. Clinical placements in hospitals are an integral part of the course.
Radiation therapists are responsible for the delivery of radiotherapy treatments prescribed by the radiation oncologist. Radiation therapists are skilled in the use of the linear accelerator (treatment machine) and other treatment equipment. Radiation Therapists give patients information on planning scans, treatment and possible side effects when they come for their first appointment.
Generally a planning CT scan is required to plan the treatment. The radiation therapists will carry this out and will put the patient in the treatment position. Certain equipment is used to keep the patient in the same position daily. The radiation therapist will apply small permanent marks to the skin or temporary skin marks so the patient’s position is reproducible every day. The radiation therapist give support to the patient at all times during the scanning procedure.
Radiation therapists are vital in the management of patients throughout their radiotherapy journey. Radiation Therapists have continual contact with patients throughout their course of treatment. They monitor and observe patients side effects from treatment and assess their emotional needs on a daily basis and give advice. Radiation Therapists work within a multidisciplinary team and refer patients to nurses, dieticians, social workers and consultants when necessary. Generally the radiation therapist’s book in the daily appointment times for treatments. Any queries regarding these can be directed to them.
Patients are required to be in the same position for treatment everyday for 10-15mins so it is important to let the radiation therapists know if it is uncomfortable at any stage. The radiation therapists are responsible for correct patient position every day and it will take them a few minutes in doing this every day. The Radiation Therapists must leave the room when they are taking x- rays images and treating, and are watching via camera at all times or through a window. If a patient requires assistance at any stage, the radiation therapists will come in immediately. The radiation therapist’s offer support to patients throughout treatment and can speak to them via intercom system if needed.
The treatment plan which is specifically tailored to each patient is monitored and checked by the radiation therapists continually, if any adjustments are required, these will be done. The radiation therapists consult with the radiation oncologist if needed. The radiation therapists are responsible for the quality assurance of the machine to insure that it is working correctly every day. This is done in the morning time before treatment starts on the machine. The radiation therapists acquire images of the treatment area prior to treatment and are highly skilled at looking at radiographic images and monitoring the daily treatments.
Please do not hesitate to speak to any radiation therapist associated with your treatment about any concerns you may have.
