The difference between two adjacent densities is

A radiograph is acquired using a source-to-image distance (SID) of 40 inches. If the radiograph is repeated using the same exposure factors, but the SID increases to 60 inches, the receptor exposure will:

A patient presents to the radiology department for a foot radiograph and upon assessment of the patient, the technologist sees that the patient has stepped on a nail and the nail is still sticking out of the plantar surface of the foot approximately two inches. This nail will create object-to-image distance (OID) that cannot be avoided on an anteroposterior (AP) foot radiograph. What steps should the radiographer take to prevent the size distortion that would be created by the long OID?

Which two of the following situations will result in grid cut-off? (Select two)

Linear grids are the most commonly used because:

Distortion can be reduced by ____________________________.

A radiographer has the choice of multiple radiographic systems, each using a different actual focal spot size. Which system should be used if maximum heat dissipation is required?

Which of the following statements describes the relationship between source-to-image distance (SID) and receptor exposure?

A radiograph acquired at 60 kilovoltage peak (kVp) results in an underexposed image. What new kVp setting will double the receptor exposure?

The magnification factor for a radiographic procedure is calculated at 1.25. It may be assumed that there is a ____ magnification of the object size.
