38. What is the primary advantage of x-ray beam filtration? Increases the heat capacity of the x-ray tube Improves image quality Lowers patient dose Provides a more even density along the length of a part 39. A steeper target angle provides more heat capacity. lower patient dose. less anode heel effect. smaller effective focal spot. 40. Filtration _______________ the average wavelength of the x-ray beam. increases decreases does not affect has no relation to 41. The precise area on the target where the x-rays strike is called the focal track. focal spot. actual focal spot. effective focal spot. 42. How is the electromagnetic induction motor used in the x-ray machine? To rotate the anode To move the tabletop To move the grid To send electrons to the filament 43. The difference in x-ray intensity (or volume of x-rays) between the anode and the cathode side of the x-ray beam is 45%. 60%. 75%. 80%.
