1.	Concerning linear tomography: a. The thickness of the plane in focus may be in the order of several mm b. The level of the imaged plane within the patient is altered by raising or lowering the pivot position c. Blurring increases with decreasing distance from the focal plane d. The tomographic angle is usually in the order of 40 e. Contrast is improved by imaging thin slices
Answer» a. True. b. True. c. False. It is those structures closest to the focal plane that are most sharply imaged. d. True. e. False. Contrast is reduced.
