All of the following statements are true regarding mA except:

Which of the following statements is/are true in regards to the line focus principle? The angle used on the anode produces an effective focal spot that is smaller than the actual focal spot. The effective focal spot is the x-ray beam that is directed towards the patient. Due to the line focus principle, the actual focal spot and the effective focal spot will always be the same size.

A characteristic curve expresses the relationship between density and exposure and permits analysis of radiographic film: Construction Speed Contrast Latitude

What is the size of an object radiographed at a 60 inch SID and a 6 inch OID if the image measures 5.5 inches?

A satisfactory radiograph is performed using 75 kVp and 18 mAs. If the kVp is decreased by 15% but the mAs remains constant, what changes will the image demonstrate? Decreased density Increased density Decreased contrast Increased contrast

Which of the following increments in OD indicates a doubling or halving in opacity?

The primary controlling factor of contrast is:

The product of mA and exposure time is equal to ____.

The heavy black densities produced on a radiographic image after processing correspond to what region of the characteristic curve?

A ____ is a device designed to expose the film to a reproducible, uniform light through a series of progressively darker filters or optical step wedges.
