Medical Dosimetrists
Dosimetrists precisely calculate the dose of radiation to ensure that the tumor receives a killing dose of radiation while minimizing the dose to healthy tissue. Most of these treatment plans are very complex and can take days to complete and evaluate. Dosimetrists work with the Physician and the Medical Physicist to select the treatment plan that is correct and best for each patient. Dosimetrists are certified by The Medical Dosimetrist Certification Board.
BEGINNING YOUR THERAPY
Beginning Radiation Therapy
When the planning is complete, you will be treated on a state-of-the-art linear accelerator. This machine generates high energy x-rays or electrons to destroy the tumor with minimal effects to the surrounding tissue. The radiation therapists may give you one or two tiny permanent tattoo marks (dots) that will replace the ink marks on your skin. You may then begin treatment. Most radiation treatments are given five times a week, Monday through Friday.
Daily Treatments
Even if the planning session went smoothly, you will probably still be nervous about your first treatment, so this section will explain what to expect on your first day of treatment and afterwards.
- Some treatments require the removal of clothing; if this is the case you will be instructed on where to change and given a gown to change into.
- A radiation therapist will then assist you into the treatment room where you will be positioned on the table in your treatment position using any custom-made immobilization devices needed.
- Your position will be checked by a series of x-rays, with minor adjustments made if necessary to match the exact treatment coordinates planned.
- The therapist may enter and exit the room before everything is set to treat. After making sure the treatment parameters are correct, the therapist will then turn on the treatment machine to deliver the dose of radiation. The machine will not function until your therapist checks that all the parameters are correct, and are verified by the computer. The machine may move around you during your treatment to deliver the cancer-killing radiation to the tumor from several different angles. You must remain completely still during your treatment, but you can breathe normally. You will not see or feel anything during your treatment, only hear the buzzing of the machine. It takes between thirty seconds and a few minutes to complete your treatment. You will be alone in the room during your treatment, but the therapist is monitoring you on an audio and visual system. The therapist may have to enter and exit the room to change equipment during your treatment.
- Your time at the center is usually between fifteen to thirty minutes daily, although there are days when emergencies happen and treatment times are delayed.
- During your course of therapy you will see the radiation oncology nurse to be weighed and evaluated. The Radiation Oncologist will see you weekly to monitor your progress and address any questions or concerns you might have.
Who gives the treatment?
Radiation therapists administer the daily treatment under the Radiation Oncologist's supervision and prescription. They record and document each treatment and run tests on the treatment machines daily to ensure that they are working properly. Radiation therapists are certified by the American Registry of Radiologic Technologists (ARRT).
Medications
You must provide a list of medications that you are currently taking to your oncology nurse. You may continue routine prescription medications unless advised otherwise by your physician. Please do not take any non-prescription medications without checking first and letting your nurse know of any changes in your medications.
Activity and Diet
Most people undergoing treatment are able to continue with their normal activities. You may need to adjust your level of activity temporarily during treatment if you feel it is necessary. Always check with your doctor before starting any exercise program during this time. Good nutrition during therapy is essential to promote good healing and recovery. You will be weighed regularly during radiation therapy to monitor your nutritional status. Do your best to eat a normal well-balanced diet with three regular meals, or, if you are unable to tolerate large portions, eat small frequent meals and snacks. Check with your doctor about multivitamins. Nutrition information is available through your oncology nurse.
Blood Counts
Blood counts must sometimes be watched carefully, especially if you are receiving chemotherapy. Your physician will order blood work if it is needed. However, many patients do not require blood work at all during their course of therap.
Driving During Therapy
Your radiation therapy should not interfere with your ability to drive. However, if you have been advised not to drive or have no transportation, please inform our staff so we can assist you with arranging transportation. |
