The thickness of absorbing material necessary to reduce the x-ray intensity to half of the original value is called:

Which of the following factors affect beam quantity?

The y-axis for all emission spectra represents the:

Factors that impact the visibility of detail include all of the following EXCEPT

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

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 OID to 8” 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

Calculate the new mAs if 15 mAs was originally used with a 16:1 grid and the repeated radiograph will use a 6:1 grid.

Spatial resolution improves with decreased _________ blur.

Which of the following focused grids will allow for the greatest amount of centering and distance lattitude:

The y-axis for all emission spectra represents the:
