Linear accelerator

A linear accelerator (also called a LINAC) is a piece of equipment most commonly used for external beam radiation treatments for patients with cancer. The linear accelerator can also be used in Stereotactic Radiosurgery comparable to that attained using the gamma knife on targets within the brain. The linear accelerator is used to treat all parts, organs of the body. A LINAC uses electricity to form a stream of fast-moving subatomic particles.

Conclusion

Implants

Internal radiation therapy (brachytherapy) is radiation delivered from radiation source. The radioactive metal is called a source and placed inside or on the body for a period of time, depending on the type of cancer the source is removed after a few minutes or a few days. Within that time the patient needs to avoid close contact with people.
