40. What device may help provide an even brightness on a radiograph of an AP axial projection of the foot? A. O Lead shield B. O Wedge compensating filter C. O Wedge positioning sponge D. O Sandbag 41. Where does the CR enter the patient for the AP projection of the first toe? A. O Base of the third metatarsal B. O Proximal IP joint C. O Metatarsophalangeal joint D. O Distal IP joint 42. When the leg is extended in the supine position, the foot is maximally dorsiflexed, and the central ray is directed 40 degrees cephalad through the plantar surface of the foot, the resulting image demonstrates A. O an axial projection of the calcaneus. B. O a medial oblique position of the tarsals and metatarsals. C. O the ankle mortise, especially the talofibular articulation. D. O the cuboid and the third cuneiform. 43. What is the proper CR angle and direction for the axial projection of the calcaneus when the ankle is dorsiflexed so that the plantar surface of the foot is perpendicular to the IR? A. O 10 degrees cephalad B. O 40 degrees cephalad on to C. O 10 degrees caudadem D. O 40 degrees caudad 44. When the leg is extended, the ankle is dorsiflexed to form an angle of 90 degrees between foot and leg, the leg is rotated medially approximately 15 degrees, and the CR is perpendicular to the IR through the midpoint between the malleoli, the resulting image demonstrates A. O an axial projection of the calcaneus. B. O an AP projection of the tarsals and metatarsals. C. O the ankle mortise, especially the talofibular articulation.
