Which of the following is NOT a function of the independent jaw movement feature?

The independent jaw movement feature is specific to radiation therapy machines, particularly linear accelerators, and plays a crucial role in optimizing treatment delivery. This feature allows the therapist to adjust the collimator jaws independently, providing greater flexibility in shaping the radiation beam.

Field matching refers to aligning two or more radiation fields to deliver a uniform dose across a treatment area. With independent jaw movement, this can be achieved with precision, making it a valuable function of this feature.

Creating dynamic wedge fields is another primary function. By varying the jaw settings during treatment, it is possible to simulate the effect of physical wedges, which help to deliver a more uniform dose distribution across the target area.

Field splitting involves dividing a larger treatment area into smaller segments to ensure a more conformal dose distribution. The independent movement of the jaws facilitates this process by allowing specific sections of the treatment field to be programmed and shaped accurately, enhancing treatment accuracy and effectiveness.

However, increasing radiation intensity is not a function of the independent jaw movement feature. The jaw movement is focused solely on shaping and conforming the treatment fields rather than changing the output or intensity of the radiation itself. The radiation intensity is determined by the machine settings and the prescribed dose, not by how the jaws are positioned.
