What is a motorized wedge integrated into the head of a linear accelerator?

A motorized wedge integrated into the head of a linear accelerator functions to manipulate the beam distribution without the need for physical wedges. Its design allows for remote control, meaning that radiation oncology professionals can adjust the wedge's position and resultant beam characteristics during treatment planning or delivery.

The primary advantage of a motorized wedge is its ability to provide greater flexibility and adaptability for beam shaping while minimizing the time and effort involved in treatment processes. This solution can adjust for varying treatment needs dynamically, allowing for precise targeting of tumor volumes and protection of surrounding healthy tissues. It streamlines operations, enabling faster adjustments compared to manual methods, thereby improving workflow and treatment efficiency.

In contrast, manual adjustments of beam intensity do not leverage the same level of precision or ease as a motorized wedge. Additionally, while other options may touch upon aspects of the accelerator's functions or operational requirements, they do not accurately reflect the capabilities and characteristics of motorized wedges as integrated tools for optimizing radiation therapy delivery.
