Which combination of variables will result in a radiograph with the lowest receptor exposure??

If an initial exposure is made using 800 mA, 0.02 sec, 16 mAs, 70 kVp, 58” SID, 4” OID, 5:1 grid ratio, 0.2 mm focal spot and 3.0 mm of filtration, with a 14 x 17 in field size, and the technologist changes the filtration to 2.5 mm Al for a second exposure without changing any other factors, what differences would you expect to see in the second exposure?1) Increased IR exposure2) Decreased IR exposure3) Increased contrast4) Decreased contrast5) Increased spatial resolution6) Decreased spatial resolution7) Increased distortion8) Decreased distortion

Which grid error results in grid cut-off and loss of exposure on the outside edges of the image receptor (IR)?

Shape distortion includes which specific types of distortion?

Which one of these types of filters is sometimes shaped like a wedge?

Penumbra (blur) decreases as

A grid with lead strips that run parallel to each other is a:

The distance between the anatomy being imaged and the focal spot is called:

The inverse square law defines the relationship between distance and:
