What does the term 'latitude' refer to in radiography?

The term 'latitude' in radiography refers specifically to the film's exposure range. This concept is critical because it defines the range of exposure levels that a given radiographic film can effectively capture and still produce acceptable images. A film with high latitude can accommodate a wider range of exposure, which means it can still yield usable images even if the exposure is not perfectly calibrated. This is particularly advantageous in settings where exposure conditions can vary significantly, as it allows for greater flexibility and reduces the likelihood of producing underexposed or overexposed films.

Understanding latitude is essential for radiographic testing as it influences the quality and reliability of radiographs. A film with inadequate latitude may result in lost detail or poor image quality if the exposure is not optimal. Hence, recognizing the implications of latitude on film performance helps technicians make informed decisions regarding exposure settings during radiographic procedures.
