ANSWERS 100% PASS.
Which of the following will produce the largest image?
A. 40" SID, 3" OID
B. 40" SID, 5" OID
C. 72" SID, 3" OID
D. 72" SID, 5" OID - ANS B. 40" SID, 5" OID
The magnification ratio = SID/SOD. A 5" OID will leave a 35" SOD (source-to-object distance)
when using 40". This will produce an image 1.14 x larger. A=1.08; C=1.04; D=1.07
Which of the following techniques will produce the highest contrast?
A. 50 mAs, 80 kVp, 5:1 grid
B. 100 mAs, 70 kVp, 8:1 grid
C. 100 mAs, 80 kVp, 8:1 grid
D. 200 mAs, 70 kVp, 5:1 grid - ANS B. 100 mAs, 70 kVp, 8:1 grid

,The lowest kVp and the highest grid ratio will produce the highest contrast.
Which of the following statements is true?
A. long grayscale has few shades of gray
B. A long grayscale is high contrast
C. A long grayscale has several shades of gray
D. High contrast has several shades of gray - ANS C. A long grayscale has several shades of
gray
Grayscale refers to the number of shades of gray in a digital image. A long grayscale would have
several shades of gray
Spatial resolution is NOT affected by which of the following?
A. SID
B. SOD
C. OID
D. kVp - ANS D. kVp
kVp will affect the visibility of detail by the amount of scatter radiation it produces. The higher
the kVp the more scatter
The quality of an x-ray beam is determined by which of the following?
A. mAs
B. kVp
C. SID
D. Focal spot size - ANS B. kVp

,Quality refers to the energy of the x-ray beam. kVp determines the energy of the x-ray beam.
Which of the following occurs when the image plate or flat-panel detector is grossly
overexposed?
A. Saturation
B. Intensification
C. Dynamic quantum
D. Dynamic inefficiency - ANS A. Saturation
If the imaging plate or detector is grossly overexposed, anatomical information will be lost. This
usually occurs in the low brightness and soft tissue areas of the image. These black areas are
referred to as plate saturation.
Which of the following will keep size distortion to a minimum?
A. Increase kVp
B. Increase grid ratio
C. Increase SID
D. Increase focal spot size - ANS C.
Which of the following types of motion must be considered when setting a radio graphic
technique?
1. Voluntary
2. Involuntary
3. Equipment
A. 1 only
2026 STUDY MATERIAL @COPYRIGHT RESERVED 3
, B. 1 & 2 only
C. 2 & 3 only
D. 1, 2, & 3 - ANS D. 1, 2, & 3
Voluntary motion can be controlled by the patient (breathing), involuntary motion cannot be
controlled by the patient(peristalsis) and motion may occur if the equipment moves.
As contrast lowers, how is the number of brightness in an image affected?
A. Increases
B. Decreases
C. Remains the same
D. Varies from image to image - ANS A. Increases
Lower contrast means a longer scale of contrast. Scale of contrast refers to the number of
different brightnesses seen in the radiograph. A long scale means there are several brightnesses
visible
What is the magnification factor is an object measures 4 cm but the radiographic image is 8 cm?
A. 2X
B. 3X
C. 4X
D. 6X - ANS A. 2X
Divide the image size by the object size to determine how many times larger the image is than
the object
Patient motion can be used to an advantage in which of the following procedures?
