Dead pixel artifact

Last revised by Dr Ali Alsmair on 16 Mar 2022

Dead pixel artifact is an artifact seen in digital radiography systems where a detector element fails to receive a proper signal and therefore appears as a bright white dot in an x-ray image. 

A defective pixel on the display monitor can also lead to a white dot appearance but it won't be seen on a physical radiograph and will remain in the same position on the screen if the radiograph is moved.
