Electron beam therapy is used in the treatment of superficial tumors like cancer of skin regions, or total skin (e.g. mycosis fungoides), diseases of the limbs (e.g. melanoma and lymphoma), nodal irradiation, and it may also be used to boost the radiation dose to the surgical bed after mastectomy or lumpectomy.
The electron beam current required to produce the X-rays is about 100 times greater than that used for electron therapy. [6] Turntable rotation. The patient is placed on a fixed stretcher. Above them is a turntable to which the components that modify the electron beam are fixed.
The beam exiting the spoiler is a combination of the spoiler-attenuated photons and the spoiler-generated electrons. The electron component alters the depth dose in the buildup region in a way that depends on the photon beam energy, the field size, and the distance of the spoiler from the treatment surface.
Intraoperative electron radiation therapy is the application of electron radiation directly to the residual tumor or tumor bed during cancer surgery. [1] [2] Electron beams are useful for intraoperative radiation treatment because, depending on the electron energy, the dose falls off rapidly behind the target site, therefore sparing underlying healthy tissue.
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 ] .

The latest recall in the beauty world just happens to involve one of the biggest at-home trends for skincare junkies and one of the leading brands in the industry.
Intraoperative radiation therapy (IORT) is radiation therapy that is administered during surgery directly in the operating room (hence intraoperative). Usually therapeutic levels of radiation are delivered to the tumor bed while the area is exposed during surgery .
