Plantar surface of foot resting firmly on radiographic table. A greater rotation can be helpful in demonstrating joint spaces of the foot. Purpose and Structures Shown To show interspaces between the following: cuboid and calcaneus cuboid and fourth and fifth metatarsals cuboid and lateral cuneiform and talus and navicular bone. For second exposure, anterior angulation of 25 degrees with CR at posterior surface of ankle so that CR emerges on plantar surface at level of lateral malleolus. Have patient place opposite foot one step backward for exposure of forefoot and one step forward for exposure of calcaneus to prevent superimposition of leg shadow.Ĭentral ray For first exposure, tube 15 degrees caudal, CR at base of third metatarsal. Position of part Affected foot on top of IR. Patient should attempt carefully maintain position of affected foot, they may need something to lean on. Position of patient Standing upright position.
#XRAY OF FOOT FULL#
Purpose and Structures Shown Full outline of foot, free of the leg. CR pointing between feet and at level of base of third metatarsals. Minimum of 15 degrees necessary to have enough room to position tube and allow patient to stand. Patient’s weight is distributed equally on each foot.Ĭentral ray 10 degrees toward heel is optimal. Place right and left markers and upright marker on IR. Position of part IR on floor, patient standing on IR with feet centered on each side. Purpose and Structures Shown To get an accurate evaluation and comparison of tarsals and metatarsals. Ensure that no foot rotation occurs.Ĭentral ray CR at base of third metatarsal and either 10 degrees toward heel to base of third metatarsal or Perpendicular to IR.įoot AP Axial (Weight-bearing method – Standing)
Entire plantar surface rests on IR take precautions against IR slipping. Position of part IR under patient’s foot flat centered on IR. Knee of affected side flexed, enough to rest sole of foot firmly on IR. Determining location of fragments in fractures of metatarsals and anterior tarsals. Purpose and Structures Shown Localizing foreign bodies. This article discusses radiographic positioning to show the tarsals and distal feet for the Radiologic Technologist (X-Ray Tech).
