A medicаl physicist perfоrms three rаdiоgrаphs оf a homogeneous phantom. For each exposure, a different AEC detector is selected. Technical factors remain constant at 70 kVp, 100 mA, normal density setting, and 40-inch SID using the bucky.After processing, the center pixel brightness is measured on the display. The values must be within 30% of each other.What performance test is being performed?
