2 ArtifactsAnything that decreases the quality of the radiograph resulting in difficult evaluation and interpretation.Problems with artifacts:Increases unnecessary re-takesMay cause misdiagnosis
3 Consistent ArtifactsIf artifact is appearing consistently, cassette should be identified and thoroughly cleaned inside and out.If fault is persistent should be labeled as faulty and put out of use.
4 Common Artifacts and Causes Film too DarkToo much kVpToo much developer timeOver-measurementMachine not calibratedSID not correct for grid use
5 Artifacts continued Film too light Underexposure, need to increase kVp or mAs.UnderdevelopedX-ray tube failureIncorrect screen-film combinationOut of calibration
6 Artifacts Continued Film gray/Lack of Contrast Too much kVp Radiation fog due to exposure filmLight leak in darkroomFilm Storage issuesExhausted chemical issuesOut of date filmLack of grid with use of high kVp’sDouble exposureToo high of wattage in safelight
7 Artifacts continued Lack of Detail Increased object-film distance Blurring due to poor screen-film contactBlurring due to patient motionBlurring due to x-ray tube motionDistorted image due to central x-ray not directed at center of filmDouble exposure
8 Artifacts Continued Heavy Lines on Radiograph Grid lines due to inappropriate use of gridRoller marks from processor issuesInconsistent film densityCollimation of primary beamBucky tray not positioned correctlyLight leak into cassetteTarget damage
9 Artifacts continued Black marks Crimping or folding of film Two films sticking together during developmentStatic ElectricityDeveloper on film before processing
10 Artifacts continued Clear areas on film Hair in cassette Scratch in film emulsionLine de to scratch on screen surfaceAir bubble in filmContrast medium on cassette or tableFilm touching side of tank during manual processing.
11 Artifacts continued Yellow Radiograph Fixer splashes on film before developingPremature age due to improper fixationFilm sticking together during fixing processIncomplete washing.
