What is a key characteristic of rotation therapy?

Rotation therapy is characterized by the machine rotating 360° around the patient during treatment. This technique allows for the delivery of radiation from various angles, which is beneficial in achieving optimal dose distribution and minimizing exposure to surrounding healthy tissues. By covering multiple angles, rotation therapy enhances the precision of dosage to the targeted area while reducing the potential for side effects.

In contrast, other options either imply fixed angles of treatment or involve rotating the patient rather than the machine, which does not align with the fundamental principle of rotation therapy. Such fixed-angle delivery can limit the effectiveness of treatment by not exploiting the full potential of varying angles for dose distribution. Therefore, the essence of rotation therapy lies in that full circular motion of the machine around the patient.
