External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators [ 1 ] .
Radiation can increase the risk of heart disease and death as observed in previous breast cancer RT regimens. [33] Therapeutic radiation increases the risk of a subsequent cardiovascular event (i.e., heart attack or stroke) by 1.5 to 4 times a person's normal rate, aggravating factors included. [ 34 ]
Tomotherapy is a type of radiation therapy treatment machine. [1] [2] [3] In tomotherapy a thin radiation beam is modulated as it rotates around the patient, while they are moved through the bore of the machine. The name comes from the use of a strip-shaped beam, so that only one “slice” (Greek prefix “tomo-”) of the target is exposed ...
To assure quality of patient care the procedure involves a multidisciplinary team consisting of a radiation oncologist, medical physicist, and radiation therapist. [9] [10] Dedicated, commercially available stereotactic radiosurgery programs are provided by the irrespective Gamma Knife, [11] CyberKnife, [12] and Novalis Radiosurgery [13 ...
A Gamma Knife typically contains 201 cobalt-60 sources of approximately 30 curies each (1.1 TBq), placed in a hemispheric array in a heavily shielded assembly. The device aims gamma radiation through a target point in the patient's brain. The patient wears a specialized helmet that is surgically fixed to the skull, so that the brain tumor ...
The 2015 update of guidelines of the Association of Gynecological Oncology (AGO), an autonomous community of the German Society of Gynecology and Obstetrics (DGGG) and the German Cancer Society includes TARGIT IORT during lumpectomy as a recommended option for women with a T1, Grade 1 or 2, ER positive breast cancer.
Macinley Butson's SMART Armour aims to limit the side effects of radiation therapy for cancer patients. This teenager's invention could revolutionize radiation therapy for breast cancer patients ...
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
