What does angular modulation utilize to modify radiation delivery?

• A. X and Y axis
• B. Tangential frequency
• C. Vertical and horizontal adjustments
• D. Curved geometry

Answer: (A)

Angular modulation employs the use of the X and Y axis to alter the delivery of radiation. This technique allows for precise control over the radiation beam by adjusting its path in a two-dimensional plane, influenced by the angular position of the source concerning the target area. By manipulating the X and Y axis, clinicians can tailor the radiation distribution to match the contours of the target volume, optimizing treatment effectiveness while minimizing exposure to surrounding healthy tissues. This method is particularly beneficial in advanced radiation therapy settings, where accurate delivery is crucial for treatment success.
