A radiograph of the shoulder is produced using 12 milliampere-seconds (mAs) and 75 kilovoltage peak (kVp) at the wall bucky. How could the technique be changed to decrease contrast while maintaining the same receptor exposure?

What is the magnification factor when an source-to-image distance (SID) of 42 inches is used and there is an object-to-image distance (OID) of 10 inches?

An increase in filtration has what effect on IR exposure?

The intensity of scattered radiation from a patient is measured as 0.1 mSv/min at a distance of 2 meters. What is the intensity at a distance of 1 meter?

Calculate the new time required to maintain the same IR exposure produced with the original values.

The SID is demonstrated on the above image by the letter:

Changing from 200 mA at 0.05 sec to 200 mA at 0.10 sec will increase:

The main purpose of added filtration is to reduce ____________.

Size distortion occurs when the:

A reduction in the kilovoltage setting during the operation of an x-ray tube will most likely:1) reduce the speed of the electron beam2) increase the filament temperature3) decrease the space charge
