Image Lag X Ray. Dark current sensitivity and image lag comparison of mercuric iodide and lead iodide x ray imagers proceedings paper. The residual signal fractions following a pulsed x ray irradiation are referred to as image lag.
Ghosting refers to the change of detector pixel sensitivity to x rays recause of previous exposures of the detector. A residual image of the lead markers indicating laterality and the performing technologist s initials from the previously acquired image is visible. 1 1 graduate school of nursing and rehabilitation sciences showa university 2 graduate school of medical health sciences komazawa university.
Lag is the carryover of image charge generated by previous x ray exposures into subsequent image frames.
Ghosting is the change of x ray sensitivity of the x ray image detector as a result of previous exposure to radiation. Image lag and ghosting in the x ray detector used. Ghosting refers to the change of detector pixel sensitivity to x rays recause of previous exposures of the detector. C and d composited image shows.
