this factor? - Answer-Maximum
For the quality area of distortion, which of the following terms best describes the requirement for this
factor in radiography in most exams? - Answer-Minimum
The greatest detrimental factor to recorded detail is the presence of ___________ unsharpness. -
Answer-Blur/Motion
Of the primary factors in the control of exposure/density, which one is not a common means of
purposely regulating the image density? - Answer-SID
Which one of the following four quality areas in radiography is the most important factor to visualizing
the image and establishing the other three? - Answer-Density
Which one of the following four quality areas in radiography is the misrepresentation of the size or
shape of the part? - Answer-Distortion
The two types of motion unsharpness are classified as ________________ and ________________ -
Answer-Vuluntary and Involuntary
, The blurred zone at the edges of the image as a result of the geometric factors is called
___________________ - Answer-Penumbra
For the following areas of recorded detail, provide the appropriate term that would give the best image
sharpness on the radiograph (longest vs. shortest, largest vs. smallest).
SID
OID
FSS - Answer-Longest SID
Shortest OID
Smallest FSS
The effective FSS is always (SMALLER or LARGER) than the actual FSS. - Answer-Smaller
Density of a radiograph is primarily dependent upon the amount of radiation (EMERGING FROM THE X-
RAY TUBE or REACHING THE IMAGING SYSTEM). - Answer-Reaching the imaging system.
Quantum mottle is an important consideration in the area of (MATERIAL UNSHARPNESS or GEOMETRIC
UNSHARPNESS) for the recorded detail of the image. - Answer-Material unsharpness
Technique adjustments for the normal patient will often be (MORE or LESS) dramatic for the
large/overdeveloped person as compared to the changes necessary for the small/underdeveloped
person. - Answer-More
T/F
Since darker films can sometimes be bright lighted and passed as an acceptable image, the technologists
should routinely take darker images to prevent repeating radiographs. - Answer-False
