Multileaf collimator

Multileaf collimator is a device used in radiation therapy to shape the radiation beam to match the shape of the tumor. The device consists of individual "leaves" that can move independently to block the radiation beam in specific areas.

Function

The main function of a multileaf collimator is to shape the radiation beam to match the shape of the tumor. This is done by moving the individual leaves of the collimator to block the radiation beam in specific areas. This allows the radiation to be delivered more precisely, reducing the amount of radiation that is delivered to healthy tissue.

Design

A multileaf collimator is typically made up of a number of individual leaves, usually between 20 and 120, that can move independently. The leaves are typically made of a high-density material, such as tungsten, to effectively block the radiation beam. The design of the collimator allows for a high degree of flexibility in shaping the radiation beam.

Use in Radiation Therapy

In radiation therapy, a multileaf collimator is used to shape the radiation beam to match the shape of the tumor. This allows for a more precise delivery of radiation, reducing the amount of radiation that is delivered to healthy tissue. The use of a multileaf collimator can improve the effectiveness of radiation therapy and reduce side effects.
