Increasing filtration would have what effect on contrast?

An portable chest x-ray is taken of a patient and compared to their chest x-ray taken when they came to the imaging department as an outpatient. What would the radiographer see?

All are considered types of noise that the radiographer may encounter on an image except:

Intensity of an acceptable image using 20 mAs, 60 kVp at 180 cm and a 10:1 grid is 20 C/kg. What would the radiographer see if the distance changed to 128 inches?

High kVp-low mAs techniques:

Decreasing kVp produces an image with:1. increased contrast2. longer scale contrast3. decreased contrast
