Which is a typical cause of image distortion in fluoroscopy?

Image distortion in fluoroscopy can be primarily linked to various factors, but one typical cause is indeed magnetic interference. This phenomenon occurs when external magnetic fields disrupt the functioning of the imaging system, leading to artifacts or distortions in the displayed images. Fluoroscopy systems are sensitive to magnetic fields, and even minor disturbances can affect the alignment and operation of the x-ray tube, image intensifier, or digital processing components. As a result, the quality and accuracy of the images can be compromised, making it critical for users to be aware of their operating environment to mitigate such interference.

While other factors like patient movement, incorrect radiation dosage, and low battery conditions can contribute to various forms of image quality issues, they do not typically fall under the category of image distortion as it relates specifically to the manipulation of magnetic fields. Understanding the impact of magnetic interference allows those using fluoroscopic equipment to maintain better image quality and ensure accurate diagnostic outcomes.
