RAD REVIEW MOCK EXAM PRACTICE TEST. 1. The brightness of a B pixel depends on all Pixel pitch of the following, ex- cept: A Bit depth B Pixel pitch C The exposure inten- sity D Brightness setting of the monitor 2. Which three state- ments are true re- garding the infero- superior axial pro- jection of the shoul- der? A The medial por- tion of the coracoid processes demon- strated B 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) B The attected arm must be abducted at least 20° D The humerus of the attected side is externally rotated E The CR is directed medially 15 to 30° The affected arm must be abducted at least 20° C Less CR angula- tion is required with greater arm abduc- tion D The humerus of the affected side is ex- ternally rotated E The CR is directed medially 15 to 30° F The greater tuber- cle is demonstrated in profile 3. If a digital radi- ographic image is produced of a pa- tient's body part and the radiogra- pher did not col- limate as closely as would be pre- ferred prior to the exposure, the ra- diographer should do which of the B Leave all exposed areas of the anatomy visible on the final image sent to the radiologist following during post-processing of the image? A Use digital mask- ing (shuttering) on the image prior to sending it to the ra- diologist B Leave all exposed areas of the anato- my visible on the fi- nal image sent to the radiologist C Repeat the pro- jection with op- timal collimation, then submit the im- age to the radiolo- gist D Use the smoothing function to elimi- nate scatter fog in the image prior to submitting the im-
