What is commonly used to reduce the effect of electronic noise in fluoroscopy?

Digital filtering techniques are employed in fluoroscopy primarily to enhance image quality by minimizing electronic noise. Electronic noise can obscure the clarity of the images captured during the fluoroscopic procedure, making it difficult to diagnose or assess conditions accurately. By applying digital filtering techniques, operators can process the acquired images to highlight relevant features while suppressing unwanted noise. This results in clearer, more precise images, allowing healthcare professionals to make better-informed decisions.

The other options do not effectively address electronic noise in the same way. Increasing brightness may enhance visibility but does not directly reduce noise levels. Changing tube angles and reducing the patient’s size may influence image quality or radiation dose but are not targeted methods for managing electronic noise. Thus, digital filtering techniques stand out as the most effective means for this purpose in fluoroscopy.
