Which parameters can be controlled directly from the x-ray control panel?

The correct choice indicates that both mA (milliamperage) and automatic exposure control (AEC) can be adjusted directly from the x-ray control panel.

Milliamperage is a critical parameter affecting the quantity of x-ray production, determining the intensity of the x-ray beam. Operators have the ability to manipulate mA settings to achieve the desired level of radiation for imaging, which directly influences image quality and patient dose.

Automatic exposure control is a feature that allows the x-ray machine to automatically adjust exposure time to ensure optimal image quality. While the operator can set parameters related to AEC, such as minimum exposure times or detector selections, the system autonomously manages the exposure based on the detected radiation levels, enhancing consistency in image quality.

Together, these parameters provide the operator with direct control over the x-ray exposure, making it possible to attain high-quality images tailored to specific diagnostic needs while also considering patient safety. This flexibility is essential in various clinical scenarios where different imaging techniques and patient characteristics might require adjustments to these settings.
