If the small filament is heated, which size focal spot would be produced?

Which of the following will produce the largest image?

If filter thickness is ________, then x-ray intensity is ________.

A technique of 10 mAs at 78 kVp is used at a 140 cm (56”) SID. What new SID should be used to decrease the exposure to 5 mAs at 78 kVp?

Assume that the usual exposure time for an AP lumbar spine is 3/4 second at 40 inches.  If you needed to use a shorter time of 3/10 second due to the condition of the patient, all other factors constant, the correct SID is:

Extremely low mAs could result in all of the following except:

Utilizing an x-ray tube with a large anode angle compared to a tube with a small angle and the same size actual focal spot results in:

Focal spot blur can be reduced by using __________.

Which of the chest radiographs would probably have the highest contrast?

All other factors equal, when mAs is reduced, the photoelectric/Compton ratio will:
