Radiation therapy
using external beam radiation therapy (EBRT) is playing an important role for
effective treatment of all kinds of tumors.
Peripheral dose
is the result of leakage and scatter from multileaf collimators devices (MLCs),
counts for 2-10% of the maximum dose given to the patient, depending on the
machine used and type of treatment.
The present
review reveals that despite of the recent advancements in linear accelerators
(LINAC) and MLC design and technology, the remaining small amount of leakage
(peripheral dose) of these devices still has significant side effects on
patient’s life span and quality of life after treatment.
