The brightness of a pixel depends on all of the following, except:
A
Bit depth
B
Pixel pitch
C
The exposure intensity
D
Brightness setting of the monitor - Correct Answers B
Pixel pitch
Explanation
The pixel pitch relates to the distance between the center of one pixel to the center of an adjacent pixel
in an image matrix (B). Bit depth refers to the range of gray (brightness) tones that a pixel can display
(A). The exposure intensity determines the gray (brightness) value displayed by a pixel (C). The
brightness on the monitor display can be adjusted during post-processing according to the evaluator's
preference (D). (Bushong, 10th ed., pp. 310-311)
Which three statements are true regarding the inferosuperior axial projection of the shoulder?
A
The medial portion of the coracoid processes demonstrated
B
The affected arm must be abducted at least 20°
,C
Less CR angulation is required with greater arm abduction
D
The humerus of the affected side is externally rotated
E
The CR is directed medially 15 to 30°
F
The greater tubercle is demonstrated in profile - Correct Answers B
The affected arm must be abducted at least 20°
D
The humerus of the affected side is externally rotated
E
The CR is directed medially 15 to 30°
If a digital radiographic image is produced of a patient's body part and the radiographer did not
collimate as closely as would be preferred prior to the exposure, the radiographer should do which of
the following during post-processing of the image?
A
Use digital masking (shuttering) on the image prior to sending it to the radiologist
B
Leave all exposed areas of the anatomy visible on the final image sent to the radiologist
C
Repeat the projection with optimal collimation, then submit the image to the radiologist
, D
Use the smoothing function to eliminate scatter fog in the image prior to submitting the image to the
radiologist - Correct Answers B
Leave all exposed areas of the anatomy visible on the final image sent to the radiologist
