Identifying The Causes of Film Artifacts

Hariette A.W.

TWO CLASSIFICATIONS OF ARTIFACTS Sensitized artifacts: • Artifacts result from any type of exposure that sensitizes the emulsion/ • Static electricity, pressure, extraneous radiation. Non-sensitized artifacts: • Artifacts result from physical damage to the film. • Dirt deposits, scratches. GENERAL RADIOGRAPHIC TIME PERIOD IN WHICH ARTIFACTS OCCUR 1. During radiographic exposure. 2. During processing of the film. 3. When the film is being handled and stores either before or after processing. EXPOSURE ARTIFACTS • Associated with the manner in which the radiographer conducts the examination. • Incorrect screen-film match. • Poor screen-film contact. • Warped cassette. • Improper positioning of Click Here To Read More

Radiographic Cassette: A Must-Read

Hariette A.W.

Radiographic Cassette: A thin light- tight container, slightly larger that the film it is intended to hold. 2 Major Parts of the Cassette The front Cover – usually made of Carbon Fiber and other plastic materials. This must be rigid and durable but radiolucent. This is made of materials with low atomic number so that it will not attenuate radiation. Back Part of the Cassette – made of steel or of light- weight material such as magnesium or lead. Others – consist of hinges and latches Carbon Fiber material used to front cover of the cassette due to its strength Click Here To Read More

Notes On Handling and Storage of Radiographic Film

Hariette A.W.

1.) In handling radiographic film be careful not to bend, crease, or otherwise subject it to rough handling. 2.) Clean hands are a must, and hand lotion and cream should be avoided. Artifacts – the marks or spurious images that sometimes appear on the processed radiograph. • Heat and Humidity Heat – reduces contrast and increases fog of a radiograph. 20 C (68 F) – temperature of a place where radiographic film is stored. 10 C (50 F) – if the film is stored for a year or longer. • Light – radiographic film must be stored in the dark.
