External beam radiation therapy commonly uses x-ray beams to treat tumors, with linear accelerators being the primary equipment used in this method.
Bolus materials are used in radiation therapy to bring the radiation dose closer to the skin surface, compensating for tissue loss and improving dose distribution for superficial tumors.
he dose prescription specifies the total amount of radiation, fractionation schedule, and the area of treatment, ensuring that the tumor receives the prescribed dose while minimizing damage to surrounding healthy tissues.
IMRT uses multiple beam angles and dynamic movement of multi-leaf collimators to modulate the intensity of the radiation beam, allowing for highly conformal dose distributions that better target tumors while sparing healthy tissue.
The linear accelerator is a device used in external beam radiation therapy to generate high-energy x-rays or electrons, which are then directed at the tumor to treat cancer.
