- lower the dose the patient gets
- lower the effect of scattered radiation
increasing its frequency

A ray is a narrow beam of light.
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.

a narrow projection of light energy radiating from a sourse into a beam
Because the beam can damage other parts of the body and tissue.A narrow beam allows focus on the treatment area with minimal additional damage.
