Learning objectives
To know how a clinical high-energy photon beam is produced through an X-
ray target and (most often) a flattening filter.
To learn about basic photon beam characteristics, such as beam quality and
lateral distributions.
To understand how the photon beam is shaped and modulated in
collimators and wedges.
2
To understand how the “raw” electron beam is converted into a flat and
clinically useable electron beam through scattering foils.
To learn about electron beam collimation.
To understand the basic characteristics of a clinical electron beam.
