Compton interactions are more likely to occur in soft tissue as compared to bone.

Recorded detail is the term commonly used in digital imaging to describe the accuracy of the structural lines that make up the image.

Shape distortion can be useful in radiographic imaging.

An increase in noise on the radiographic image:

Remnant radiation will be reduced by one half for every additional ________ of part thickness.
