What is a method to prevent detector fog in computed radiography?

Preventing detector fog in computed radiography is crucial for maintaining image quality, and one effective method is to protect the cassette before and after exposure. This involves safeguarding the imaging plate from exposure to ambient light and other sources of radiation that could cause the detector to become fogged.

Computed radiography systems use photostimulable phosphor plates to capture images, and these plates can be sensitive to light exposure. When exposed to unintended light before or after the radiographic procedure, the plates can develop a fogged appearance, which degrades the overall image quality. By ensuring that the cassette is covered and handled properly—particularly in dark conditions or using protective covers when not in use—technologists can significantly reduce the risk of fogging, leading to clearer and more diagnostically useful images.

Feeling secure about the conditions under which the imaging plates are stored and the precise ways in which they are handled will directly impact the fidelity of the resulting radiographic images.
