What is exposure latitude defined as?

Exposure latitude is defined as the range of exposure that produces quality images at an appropriate patient dose. This concept is crucial in digital radiography because it indicates the flexibility in adjusting exposure settings without compromising image quality. A wider exposure latitude means that the radiographic system can accommodate a broader range of techniques while still ensuring that the resulting images are of diagnostic quality and do not subject the patient to unnecessary radiation.

This characteristic is particularly important in clinical practice, as it allows radiologic technologists to manage varying patient conditions, positioning, or anatomical variations and still achieve adequate imaging results. The correct understanding of exposure latitude aids in optimizing image acquisition, thereby enhancing both patient safety and diagnostic efficacy.
