Overview Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy used to treat cancer and noncancerous tumors. IMRT uses advanced technology to manipulate photon and proton beams of radiation to conform to the shape of a tumor. IMRT uses multiple small photon or proton beams of varying intensities to precisely irradiate a tumor. The radiation intensity of each beam is controlled, and the beam shape changes throughout each treatment. The goal of IMRT is to conform the radiation dose to the target and to avoid or reduce exposure of healthy tissue to limit the side effects of treatment.

Medical imaging Nuclear medicine radiologists, also called nuclear radiologists, are physicians who use radioactive materials, called radiopharmaceuticals, to diagnose and treat disease. They employ such techniques as scintigraphy, which uses radiopharmaceuticals to produce images of the body's organs or to visualize certain diseases.uclear medicine physicists have a master's or doctorate degree in one of the following fields: 1  Physics. 2  Medical Physics. 3  Radiologic Physics. 4  Engineering. 5  Applied Mathematics. 6  Other physical sciences.

Radiation Therapy Radiation therapists help one patient at a time fight cancer. The Associate in Science in Radiation Therapy degree immerses students in the field of cancer care. Radiation therapists treat cancer in patients by administering radiation treatments using machines called linear accelerators.

Radiation Therapy Some people with Stage 0 (DCIS) and most people with Stage 1 invasive cancer and higher, who have had a lumpectomy, can expect radiation therapy to be a part of their treatment regimen. Most radiation therapy is administered by a radiation oncologist at a radiation center and usually begins three to four weeks after surgery. The radiation is used to destroy undetectable cancer cells and reduce the risk of cancer recurring in the affected breast. There are two main kinds of radiation therapy that may be considered, and some people have both. External Bearm Breast Cancer Radiation (Traditional cancer-killing rays delivered by a large machine)

Radiation therapy Radiation oncology is the medical specialty concerned with prescribing radiation, and is distinct from radiology, the use of radiation in medical imaging and diagnosis. Radiation may be prescribed by a radiation oncologist with intent to cure (curative) or for adjuvant therapy.adiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth.

- An experienced therapist can rise to take on additional responsibility in a managerial role. With additional education and certification, you could even become a dosimetrist, who calculates the amount of radiation required for treatment.. Attend a college with an accredited radiation therapy program. In addition to learning about radiation therapy procedures, these programs will generally require coursework in human anatomy and physiology, physics, algebra, computer science, and research methodology.

- When the exact dose of radiation to the prostate is determined, the patient returns for a treatment simulation. The simulation process transposes or maps the computer-generated plan to the patient. The doctor will review the treatment course and side effects with the patient.

What does a Radiation Therapist do? A radiation therapist uses the process of ionizing radiation to treat cancer patients. Radiation therapists are also known as therapeutic radiographers or radiotherapists. They sometimes are incorrectly called radiation technicians or radiation therapy technicians.

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. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer).

Radiation The type of radiation therapy prescribed by a radiation oncologist depends on many factors, including: The type of cancer. The size of the cancer. The cancer’s location in the body. How close the cancer is to normal tissues that are sensitive to radiation.

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. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.he precise treatment intent (curative, adjuvant, neoadjuvant, therapeutic, or palliative) will depend on the tumor type, location, and stage, as well as the general health of the patient. Total body irradiation (TBI) is a radiation therapy technique used to prepare the body to receive a bone marrow transplant.

radiation therapy Definition of Radiotherapy. Radiotherapy: The treatment of disease with ionizing radiation. Also called radiation therapy. In radiotherapy, high-energy rays are often used to damage cancer cells and stop them from growing and dividing. A specialist in the radiation treatment of cancer is called a radiation oncologist. Like surgery, radiation therapy is a local treatment; it affects cancer cells only in the treated area.

- What does a Radiation Therapist do? Radiation therapists use ionizing radiation to treat cancer patients. A radiation oncologist must go over the risks and benefits of each treatment before a plan can be put into place. Radiation treatment to the head and neck may damage salivary glands, causing a decrease in saliva production and dry mouth.

What is Medical Oncology? Oncology is a specialty within the field of medicine that focuses on the study and treatment of all malignant tumors or cancer. There are several sub-specialties that fall under the category of oncology. Medical oncology is such a category in which drugs, chemotherapy, and other related therapies — like biological response modifiers and hormone therapies — are used to treat cancer. A doctor who practices oncology is called an oncologist.
