Radiographic image analysis chapter 1
and 2 exams questions and answers
The patient demographic requirements for radiographic images include all of the
following except: - ANSWERS:Technologist identification
Which of the following is true about image markers
1. They are radiopaque
2. They should be reversed before being placed on the IR.
3. They should be positioned as close to the median plane as possible.
4. They will be magnified is positioned on the imaging table or patient - ANSWERS:1
and 4 only
What is the marker placement for the projection of lateral vertebrae -
ANSWERS:Anteriorly identifying the side position closer to the IR
What is the market place mat for the PA projection cranium - ANSWERS:Laterally on
the side being identified
What is the marker placement for the projection of PA oblique vertebrae -
ANSWERS:Laterally identifying the side situated closer to the IR
What is the marker placement of the projection of lateral hand - ANSWERS:Anywhere
within the exposure field
Which guideline should be used to position the identification plate - ANSWERS:Position
the ID plate toward the direction in which the central ray was angled
Good collimation practices will do all the following except - ANSWERS:Reduce the
visibility of recorded details
Elongation occurs in all of the following situations except when - ANSWERS:Central ray
and I are are perpendicular and the part is angled
For an open joint base to be obtain the central ray must be aligned ——— to the joint -
ANSWERS:Parallel
When is essential right angle, the structure situated —— is projected the most -
ANSWERS:Farther away from the IR
Three images were obtained on the same structure with the computed radiography
system. Image one was obtain using a 48 inch source image receptor distance (SID)
and a 5 inch object image receptor distance (OID) image to was a chain using a 48 inch
, SID in a 3 inch OD and immature he was obtained with a 48 inch SID the 3 inch OID
and a larger IR. Which image would demonstrate the sharpest recorded detail? -
ANSWERS:Image 2
Three images were obtained on the same structure with the computer the radiography
system. Image one was obtained using a 48 inch source image receptor distance (SID)
and a 5 inch object image receptor distance (OID). Image to was obtain using a 48
inch(SID) and a 3 inch (OID) and image three was obtained with a 40 inch SID and a 3
inch 0ID and a larger IR. Which image would demonstrate the greatest size distortion? -
ANSWERS:Image 1
A small focal spot should be used for each of the following situations except when -
ANSWERS:The Mili amperage setting is above 300
And image demonstrating motion in adequate density was obtained using 100 mA at 0.5
seconds. If the time is changed to 0.25 seconds what mA should be used to maintain
density? - ANSWERS:200 mA
Anatomical relationships are affected by:
1. Varying degrees of patient of liquidy and flexion
2. Off centering
3. Geometrical factors of magnification elongation, and foreshortening
4.Similar structures of shape and size - ANSWERS:None of the above
Good collimating practices result in which of the following?
1. Reduces histogram analysis errors
2. Clearly delineates the VOI
3. Improve the visibility of recorded details by reducing the amount of scatter radiation
that reaches the IR
4. Decreases the radiation dosage by limiting the amount of scatter from the patient -
ANSWERS:1,2, and 3 only
Minimizing size distortion is accomplished by which of the following:
1. Using the longest feasible SID
2. Using the shortest possible OID
3. Decreasing the angle of the CR
4. Placing the part as close to the IR as possible - ANSWERS:1, 2 and 4 only
Collimation guidelines include all of the following except for :
1. Chest and abdomen projections collimate within 1 inch (2.5 cm) of the patient's skin
line
2. Extremity projections Colome within 0.5 inch (1.25 cm) of the skin line of the thickest
VOI
3. Chest and abdomen projections call me within 0.50 inches (1.25 cm) of the IR edge.
4. Collimating structures within the torso bring the collimated borders to within 1 inch
(2.5 cm) of the VOI. - ANSWERS:1 and 3
