How do X-ray variable-aperture collimators differ from fixed-aperture collimators in terms of functionality?

X-ray variable-aperture collimators and fixed-aperture collimators both serve to limit the X-ray beam to the area of interest during medical imaging. However, they differ in terms of functionality.

Fixed-aperture collimators have a set, unchangeable field size, requiring manual adjustment or replacement for different imaging scenarios. They are simpler and less flexible, often requiring the radiographer to physically adjust the collimator to achieve the desired field size.

On the other hand, variable-aperture collimators offer greater flexibility by allowing the radiographer to electronically adjust the field size without changing collimator accessories. This dynamic adjustment capability enhances precision and efficiency, adapting to varying patient sizes and anatomical regions. Variable-aperture collimators contribute to dose optimization and workflow efficiency in modern radiography, enabling more adaptable and patient-specific imaging settings. Whatsapp:+86 18953679166.
