What is IMRT (Intensity Modulated Radiation Therapy)?
Patient Information - Frequently Asked Questions:Radiation O...IMRT involves varying (or modulating) the intensity of the radiation (in this case, X-rays), being used as therapy for cancer. It is a new form of radiation therapy that uses computer-generated images to plan and then deliver more tightly focused radiation beams to cancerous tumors than is possible with conventional radiotherapy.
Related QuestionsWhat is Intensity-Modulated Radation Therapy (IMRT)?
Cancer Care Of North Texas :: Frequently Asked QuestionsIntensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that utilizes computer-controlled x-ray accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor.
Related QuestionsWhat is radiation therapy?
Community Cancer Care: FAQRadiation is a special kind of energy carried by waves or a stream of particles. It can come from special machines or from radioactive substances. When radiation is used at high doses (many times those used for x-ray exams), it can treat cancer and other illnesses. Special equipment is used to aim the radiation at tumors or areas of the body where there is disease. The use of high-energy rays or particles to treat disease is called radiation therapy.
Related QuestionsHow is Varian’s SmartBeam IMRT different from other forms of radiation therapy?
Patient Information - Frequently Asked Questions:Radiation O...The system achieves a very high resolution and therefore maximizes tissue sparing. With SmartBeam IMRT, a computerized tool called a multileaf collimator (MLC) shapes the beam in accordance with the optimized treatment plan. Varian offers the highest resolution MLC on the market today, one that can deliver unique doses to very small areas. In addition, Varian’s SmartBeam IMRT is fast. The patient is only positioned once per session, rather than multiple times.
Related QuestionsWhat kind of radiation is used in IMRT?
Patient Information - Frequently Asked Questions:Radiation O...Currently, photons (X-rays) are used to deliver IMRT. The radiation is generated by a machine called a medical linear accelerator. This machine stands approximately nine feet tall, and nearly 15 feet long and can be rotated around the patient with great precision. Operationally, microwave energy, similar to that used in satellite television transmission, is used to accelerate electron to nearly the speed of light.
Related QuestionsContact PageRadiation therapy uses an invisible beam of high-energy particles, such as electrons, or waves, such as x-rays, or gamma rays to destroy or damage cancer cells. Other names for radiation therapy include radiotherapy, x-ray therapy, electron beam irradiation, and some older forms of radiation therapy using radioactive Cobalt. The first patient with cancer to receive radiation treatment for her tumor was treated in 1896, just one year after the “discovery” of X-rays.Related Questions
Frequently Asked Radiation Therapy QuestionsRadiation therapy is a highly effective, pain-free treatment option used to cure or control the spread of cancer, bring relief to symptoms including pain, and to improve the quality of life of a patient with cancer. Radiation therapy is used on up to 80% of all cancers including breast cancer, lung cancer, prostate cancer, skin cancer, brain tumors and more. Radiation therapy involves the use of various kinds of radiation treatment techniques.Related Questions
Radiation Treatment Center - Frequently Asked Questions - M....Radiation therapy, sometimes called radiotherapy, effectively treats cancer by using high-energy beams to pinpoint and destroy cancerous cells. Although radiation therapy is similar to an X-ray, the dose of radiation in cancer treatment is much stronger and is given over a longer period of time. Many forms of radiation are available. Your oncologist will choose the best therapy based on the type, stage and location of your cancer.Related Questions
Why do some people need radiation therapy and not others?
Community Cancer Care: FAQAfter a diagnosis of cancer, a doctor will consider several factors in determining the course of treatment that will be most successful for a particular patient. These factors include the type of tumor, site of origin and the stage and grade of disease. These factors affect the likelihood of a particular therapy slowing down or stopping the disease process. In some cases, only one specific therapy may be appropriate.

Patients' Frequently Asked Questions (PFAQ) - CancerRadiation Therapy is the delivery of treatment using radiations from natural or artificial sources to treat disease, most often cancer. Natural sources include Cobalt-60, Iodine-131, Iodine-125, Gold-189, and isotopes or other variants of other elements as well. Radiations are produced or emitted by these elements and are used like x-rays.Related Questions
What is Low Intensity Laser Therapy (LILT)?
Sun Valley Laser Therapy - Frequently Asked QuestionsLILT is the use of monochromatic light emission from a low intensity laser diode (250 milliwatts or less) or an array of high intensity, super luminous diodes (providing total optical power in the 1000-2000 milliwatt range) to treat musculoskeletal injuries, chronic and degenerative conditions and to heal wounds.
Related QuestionsWhat is intensity?
Gamma FAQ - Frequently Asked Questions about GammaRadiant intensity refers to radiant power (flux) in a particular, specified direction. Formally, it is the rate at which radiant energy is transferred, per unit solid angle. Radiant intensity is expressed in watts per steradian (W · sr-1). It is what I call a linear-light measure. Radiant intensity potentially has a large spatial extent, but imaging systems use pixels with small area: It is inappropriate to use intensity as a metric for image data.

BASCOM PALMER EYE INSTITUTE: FREQUENTLY ASKED QUESTONSThe type of radiation used in eye-plaque therapy should not cause hair loss, nausea, brain damage, or affect your other eye. Once the radiation plaque is removed, there will be no radiation left in your body, on your clothing, or on any of your personal belongings. The effects of the radiation delivered to your tumor and eye will continue to be observed for months and years after treatment.
Related QuestionsHow is the radiation therapy given?
Frequently Asked QuestionsRadiation is aimed from machines outside the body (external beam radiation) or is introduced into the body via materials called radioisotopes. This kind of internal radiation is called interstitial radiation or brachytherapy. Radioisotopes are placed in or near the tumor or in the area of the cancer cells. Systemic radiation therapy uses a radioactive substance that circulates throughout the body.
