Can X-ray collimators be adjusted for variable source-to-image distance (SID) scenarios?

Yes, X-ray collimators can typically be adjusted for variable source-to-image distance (SID) scenarios. Collimators are equipped with adjustable blades or apertures that control the size and shape of the X-ray beam. By adjusting these blades, radiographers can modify the beam size to match different SID settings. Some collimators may also have additional features such as light-localizing devices or laser guides to aid in precise alignment.

However, it’s important to note that while collimators can adjust the size of the X-ray beam, they do not directly compensate for changes in image magnification or distortion that may occur with varying SID. Radiographers must still consider factors such as patient positioning and image quality when adjusting SID. Regular calibration and maintenance of collimators are essential to ensure accurate and consistent performance across different SID scenarios, thereby facilitating optimal X-ray imaging quality and radiation dose management. We are a manufacturer of X-ray machines and their accessories.
