Where should the image receptor be placed for an AP projection of the fifth digit of the foot?

• A. Under the foot on the tabletop
• B. Above the table
• C. On the patient’s shoe
• D. Beside the foot

Answer: (A)

For an AP view of the little toe, the image receptor must be placed directly under the part being imaged to minimize distortion and keep the digit sharp. Position the patient with the plantar surface resting on a table and lay the image receptor flat on the tabletop under the foot so the fifth toe sits directly on it. This arrangement lets the x-ray beam pass through the toe perpendicularly and captures the distal phalanx through the metatarsophalangeal joint with accurate size and detail. Placing the receptor above the table, on the patient’s shoe, or beside the foot would create gaps, shadows, or obstructions that blur or distort the image and fail to visualize the toe properly.
