The quality (meaning the type, energy, and penetration) of the beam produced by any particular radiotherapy machine should be understood so that the machine will be used properly on patients. The penetration characteristics of any beam should be evaluated by experimental measurements.

Theoretical Framework and Hypotheses,anifestation of these waves. After presenting the classical description based on wave theory that applies to their macroscopic behavior, we briefly introduce the quantum-mechanical concepts that operate on atomic and microscopic scales, as needed for the purposes of this book.

Electrons play a key role in radiation energy absorption processes that are exploited in routine radiotherapy. In this chapter, we focus attention mainly on moving electrons.

He called the radiation ”X-rays,“ using the letter ”X“ to designate something unknown. Nowadays, these rays are also called Roentgen rays. Roentgen’s radiographing of his own and his wife’s hands marked the beginning of the use of X-rays in the healing arts.
