The function of Automatic Exposure Control (AEC) in radiography is:
to automatically adjust the amount of radiation exposure for optimal image quality
to increase the size of the X-ray image
to reduce the cost of radiographic equipment
to enhance the color of the radiographic image
The imaging modality most useful for demonstrating GI perforations is:
Ultrasound
CT scan
MRI
Barium swallow
A common chest pathology seen in pediatric radiography is:
Pneumonia
Emphysema
Pulmonary fibrosis

The purpose of using a grid in scatter control is:
to limit the amount of scatter radiation reaching the image receptor
to increase patient exposure to radiation
to blur the image intentionally
to reduce the sharpness of the image
