Preventing and Addressing Unwanted Artifacts in Radiographic Imaging: Causes of Increased Density and How to Minimize Them

Increased density on the radiographic image caused by extraneous heat, light, or chemical fumes.

When it comes to radiographic imaging, there are a few factors that can cause increased density on the image, also known as unwanted artifact

When it comes to radiographic imaging, there are a few factors that can cause increased density on the image, also known as unwanted artifact. Three common causes of increased density are extraneous heat, light, and chemical fumes. Let’s examine each one in detail:

1. Extraneous heat: Exposure to excessive heat can result in increased density on the radiographic image. Heat can affect the film emulsion, causing it to exhibit a higher level of sensitivity to X-ray radiation. Consequently, when the film is exposed to X-rays during the imaging process, it absorbs more radiation and appears denser on the final image. This can occur if the films were stored in an area with high temperatures, or if they were exposed to heat during the development process.

2. Extraneous light: Another factor that can lead to increased density on radiographic images is exposure to extraneous light. Radiographic films are highly sensitive to light, and any exposure to light before or after the imaging process can produce unwanted artifacts. When the film is exposed to light, it causes a chemical reaction in the emulsion, resulting in increased density. This commonly happens when the film cassettes are inadvertently opened prior to processing or when the film is improperly handled in a brightly lit area.

3. Chemical fumes: Chemical fumes can also contribute to increased density on radiographic images. During the film development process, various chemicals are used to develop and fix the image on the film. If the chemicals or the processing equipment are contaminated with fumes, it can affect the film’s emulsion and lead to increased density. This can happen if the chemicals are not properly stored, have expired, or if there is poor ventilation in the darkroom where the film processing takes place.

To minimize or prevent these artifacts, it is essential to follow proper handling and storage protocols for radiographic films. Films should be kept in a cool and dry environment, away from excessive heat sources. Additionally, films should not be exposed to light except during the imaging process. Lastly, it is crucial to ensure proper ventilation and adherence to safety guidelines while working with film processing chemicals.

Regular maintenance and quality control checks should also be performed on processing equipment to ensure that chemicals are not contaminated with fumes that can lead to increased density on radiographic images.

By being aware of and addressing these potential causes of increased density, radiographers can obtain clear and accurate images that aid in accurate diagnosis and treatment.
