S-Values - Digital Radiology
What does an S-value represent and how is it monitored?
S-values or “sensitivity” values represent the numeric value of exposure received by the receptors in the digital system. This represents a key value in monitoring that a quality radiograph is obtained with the least amount of dose to the patient.
The S-value is automatically recorded by the software for every exposure taken on a particular digital system.
The illustration on the right shows that an optimal CXR in this office has an S-value of 200.
Your X-ray service company versed in digital technology can ensure that YOUR exposures fall within acceptable ranges.
