What is a dosimetrist?

Dosimetrists are medical professionals who work in radiation oncology helping to care for cancer patients. Among their various job responsibilities, a dosimetrist has the important task of applying the appropriate dosage of radiation at the correct part of the body. This is typically done through a variety of high-tech medical equipment.

Prior to the treatment, dosimetrists explain the procedure to patients and answer any questions or concerns they may have. They also work closely with physicians to determine the required amount of radiation and duration of treatment. Dosimetrists ensure the safety of patients during treatment and make sure equipment is working properly. After treatments, they monitor patients for any negative side effects. They also keep detailed records of all treatments they have administered.

What does a dosimetrist do?

When a radiation oncologist prescribes radiation to treat a patient’s cancer cells or tumor, a dosimetrist develops a plan to deliver the prescribed dose of radiation. The dosimetrist uses a computer that comes with three-dimensional imaging software to contour the patient’s organs on a treatment planning CT scan. They may also perform image fusion using CT, MRI or PET/CT to help the radiation oncologist identify where the tumor is located.

The dosimetrist then develops a three-dimensional conformal or intensity-modulated radiation therapy plan and identifies an arrangement of beams to apply the radiation on the patient’s tumor or cancer cells while minimizing damage to normal organs. Physics calculations are performed, and the radiation oncologist and medical dosimetrist check the dose in relation to the organs and tumor at risk.

Once the course of treatment has been approved by the radiation oncologist, the dosimetrist prepares the treatment plan and makes sure it will work as planned. The dosimetrist works closely with the radiation therapist when administering the treatment plan. In addition, dosimetrists may help medical physicists in quality assurance procedures, train dosimetry students and work on research teams to help improve the efficacy of radiation therapies.

Dosimetrist skills

Successful dosimetrists need to have a deep understanding of medical physics and radiation oncology, drawing from math, physics and biology to form integrated solutions. Aside from a bachelor’s degree and a state license, employers look for medical dosimetrists who demonstrate the following skills:

  • Knowledge of clinical oncology: To create treatment plans for patients, dosimetrists must be good in radiation therapy and clinical oncology. They should be capable of analyzing test results as well as understanding the body mechanisms behind a patient’s reaction to radiation therapy.

  • Mathematical skills: Complex computations are important to radiation treatment, which requires accurate figures for dosage, equipment angles and exposure time. Dosimetrists also need mathematical skills for generating and interpreting three-dimensional visualizations.

  • Teamwork: Dosimetrists must be able to work harmoniously with the staff members, including medical physicists, radiation therapists and physicians. To have a smooth implementation of treatment plans, dosimetrists must communicate well and execute details accurately.

  • Problem-solving skills: When developing treatment plans for patients, dosimetrists consider a lot of factors and examine risks to determine the most effective method. They must also be able to modify their strategy in the case of unpredictable results.

  • Listening and communication skills: It’s also important for dosimetrists to have excellent listening and communication skills. Dosimetrists must first listen carefully to the physician and radiation oncologist to understand treatment goals, accurately record the treatment plan and then explain it to the radiation therapist responsible for the implementation of the treatment plan.

Working conditions

Medical dosimetrists typically work a normal 40-hour week in a hospital, cancer treatment center or physician’s office. Because radiation therapy procedures are typically planned in advance, dosimetrists keep a regular work schedule. However, they are on their feet for long periods and they may need to turn or lift disabled patients.

Because they often work with radiation and radioactive equipment, dosimetrists must follow safety procedures to make sure that they are not exposed to a harmful amount of radiation. These safety procedures typically require dosimetrists to stay in a different room while the patient undergoes radiation treatment.
