The unsharp,"fuzzy" appearance of margins of anatomic structures within the radiographic image is called:
The distance between the subject or part and the IR is referred to as:
A) object-image receptor distance (OID).
B) part-receptor distance (PRD).
C) source-receptor distance (SRD).
D) source-image receptor distance (SID).
A change from the small focal spot to the large focal spot results in:
A) decreased resolution.
D) increased contrast.
With a large OID,the reduction of excessive magnification is accomplished by:
A) increasing the SID.
B) increasing the kVp.
C) decreasing the SID.
D) decreasing the kVp.
