The universal wedge in radiation therapy is characterized by its ability to be utilized with a treatment head that can slide into an open field. This design allows for flexible treatment planning and the ability to achieve desired dose distributions across varying patient anatomies. Unlike fixed wedges or those limited to specific field sizes, the universal wedge can adapt to a range of treatment scenarios, thereby providing significant versatility in achieving optimal dose delivery.

This adaptability is essential for dosimetrists who need to account for patient-specific considerations, such as tumor shapes and surrounding tissues. An effective wedge can help to modify the radiation beam's intensity and distribution, improving the irradiation pattern to deliver therapeutic doses to tumors while sparing adjacent healthy tissues. This feature is key in modern radiation therapy practices, highlighting the importance of personalized treatment approaches.
