What should sequential increases in mAs produce in exposure measurements?

Sequential increases in milliampere-seconds (mAs) should produce linearity in exposure measurements because the relationship between mAs and exposure is directly proportional. This means that as you increase the mAs, you should see a corresponding increase in exposure that follows a predictable, straight line when graphed.

Linearity is crucial in quality control because it confirms the consistency and reliability of the radiographic equipment's response to changes in exposure settings. When an increase in mAs results in an increase in exposure that is directly linked to the amount of mAs used, it demonstrates that the equipment is functioning properly and produces consistent results.

In a well-calibrated system, each incremental adjustment in mAs leads to a proportional adjustment in exposure. This allows radiographers to make accurate adjustments to achieve the necessary exposure levels, ensuring optimal image quality and patient safety.
