External Beam Radiation Therapy (EBRT):
EBRT is the general or generic term used to describe radiation treatment that is produced outside the body from a machine and is aimed and delivered to a target within body. EBRT compasses a broad spectrum of advanced technologies designed to deliver targeted radiation treatment to cancer cells with unparalleled precision. This method leverages high-energy beams, such as photons (X-rays), electrons or protons, directed at the tumor from outside the body, minimizing damage to surrounding healthy tissues. At the core of EBRT’s effectiveness are its capabilities in accuracy, advanced imaging integration, and versatile dose delivery mechanisms, catering to a wide array of cancer types and individual patient needs.
Various types of machines (linear accelerators) are made for delivering radiation for EBRT including technologies such as Stereotactic Radiosurgery (SRS), Stereotactic Body Radiotherapy (SBRT), Volumetric Modulated Arc Therapy (VMAT) and Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT) and Respiratory Gating.
