Outline

Text

In the scope of this lecture an introduction will be given to the management of target motion in particle beam therapy with an emphasis on beam scanning. Implications of target motion on the whole therapy chain from imaging to treatment validation will be presented. Especially with respect to dose delivery the implications of scanned vs. a scattered beam delivery will be explained while details will be covered in the Image-Guided Particle Therapy session on October 2nd.

The learning objectives are:

  • Ability to define the different types of target motion
  • Understand the implications the radiological path-length has on the definition of the planning target volume
  • Name detriments and advantages of scanned beam delivery and scattered beam delivery for the irradiation of a moving organ
  • Explain the principles of gating, rescanning, and beam tracking
