The concept of a compensator being considered demagnified in treatment is related to its positioning in the treatment setup. When a compensator is kept closer to the radiation source, it effectively alters the distribution of dose in the treatment area. This positioning minimizes the distance between the compensator and the radiation beam, resulting in less scattering and a more precise delivery of the intended dose to the target area.

Keeping the compensator closer to the source means that the effect it has on the radiation beam is more pronounced, allowing for a more controlled modulation of the dose. This helps in compensating for patient contour or irregularities, ensuring that dose distributions are adjusted adequately for the areas being treated.

Understanding the role of a compensator in radiation therapy is crucial, as it plays a significant part in achieving optimal dose conformity and sparing healthy tissue surrounding the tumor.
