External radiation is usually done during outpatient visits to a hospital or treatment center.

External radiation therapy device. External beam radiotherapy ebrt is the most common form of radiotherapy radiation therapythe patient sits or lies on a couch and an external source of ionizing radiation is pointed at a particular part of the body. Radiation oncologists use linear accelerators or cobalt machines to deliver external beam therapy. Your radiation oncologist will determine the equipment most suited to your treatment.

Linear accelerator see linear accelerator page. Modern machines better focus the radiation and do less damage to normal tissues so doctors can use higher doses of radiation. The linear accelerator is the most commonly used device for external beam therapy.

Place special devices called wedges in the path of the beam to bend the dose of radiation away from normal tissues under the breast. A machine directs a beam of radiation through the skin to a specific part of the body usually a tumour. The oncologist evaluates the patient identifies the treatment and determines the appropriate therapy and radiation dose.

The radiation oncologist is a highly trained doctor who specializes in treating cancer with radiotherapy. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. External radiation therapy is also called external beam radiation therapy.

Radiation therapy or radiotherapy often abbreviated rt rtx or xrt is therapy using ionizing radiation generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. In some cases a surgeon will assist by placing treatment devices in the patient. You cant see or feel external radiation therapy.

In contrast to brachytherapy sealed source radiotherapy and unsealed source radiotherapy in which the radiation source is inside the body external beam radiotherapy directs. With the purpose of reducing stray radiation dose srd in outoffield region ofr during radiotherapy with 6 mv intensitymodulated radiation therapy imrt a bodyshielding device bsd was prepared according to the measurements obtained in experimental testing. During the final week or so of the radiation regimen you will also receive a supplemental dose of radiation targeted directly to the area around your surgery where the cancer was.

External beam radiation therapy comes from a machine that aims radiation at your cancerit is a local treatment which means it treats a specific part of your bodyfor example if you have cancer in your lung you will have radiation only to your chest not to your whole body.
