What does a series of images acquired using different mA levels exemplify?

A series of images acquired using different milliampere (mA) levels exemplifies exposure latitude. Exposure latitude refers to the range of exposure levels that will produce usable images at a given quality. By varying the mA, which affects the quantity of radiation used during the imaging process, you can observe how the resulting images maintain quality across different exposure levels. This is particularly important in radiography, as it allows for some flexibility in determining the proper exposure needed to achieve diagnostic images without compromising quality.

The practice of varying mA levels helps to demonstrate the limits of exposure that can be tolerated by the imaging system while still generating clinically relevant images. Observing changes in image contrast and density across these exposures can provide insights into the system's response to different radiation levels, illustrating the concept of exposure latitude in the imaging process.
