Radiographic Image Analysis Final
Which of the following demonstrates one end of a structure of interest appearing disproportionately
longer than the opposite end? -
Elongation
(True/False)
The farther away a part is from the IR the more magnification is demonstrated. -
True
The least amount of divergence in the xray beam is found: -
The center of the central ray
Which of the following will help produce better spatial resolution? -
Longer SID
When marking a lateral lumbar spine, it is preferred to place the marker anterior, why? -
The marker may be over-exposed and not seen on the image
Which of the following is true when using an angled CR beam? -
As the angle increases, the degree of anatomical part movement increases
The technologist can compensate for increased OID by: -
Increasing SID
To prevent unacceptable entrance skin dose, the skin to source distance should be no less than: -
12"
(True/False)
When an image is mismarked, the technologist should annotate directly over the marker -
False
(True/False)
The thicker the part being imaged, the smaller the collimator light field appears on the patients skin
surface thus requiring the technologist to decrease collimation -
False
(True/False)
Clipping of required anatomy may occur due to divergence of the xray beam -
True
Gonadal shielding should be used when the primary beam is within ______ inches of the gonads. -
2
Collimation best practices states the xray beam should be narrowed to include the required VOI and
_________. -
