What describes a dynamic wedge?

A dynamic wedge refers to a technique used in radiation therapy where a moving jaw or collimator modifies the beam's shape to create a wedge effect. This wedge effect is critical for allowing a more conformal dose distribution to the tumor while sparing surrounding healthy tissue. Unlike a physical wedge, which is a static device placed directly in the beam path, the dynamic wedge is designed to adapt during the treatment process, providing improved flexibility and optimization for larger treatment areas.

The ability of the moving jaw to create varying degrees of wedging allows dosimetrists and radiation oncologists to tailor the treatment plan according to the specific needs of the patient, particularly when dealing with larger treatment volumes or complex tumor geometries. This adaptability enhances the overall treatment quality by ensuring that the radiation dose is delivered accurately and effectively, thus maximizing the therapeutic benefit while minimizing damage to adjacent healthy tissues.

In summary, the definition of a dynamic wedge emphasizes its functionality and adaptability in radiation therapy, setting it apart from static devices. The versatility of the moving jaw mechanism directly contributes to improved treatment outcomes.
