How should the foot be positioned for tangential imaging of the sesamoid bones?
plantarflexed with the heel of the foot perpendicular to the image receptor
plantarflexed with the ball of the foot perpendicular to the image receptor
dorsiflexed with the heel of the foot perpendicular to the image receptor
dorsiflexed with the ball of the foot perpendicular to the image receptor
dorsiflexed with the ball of the foot perpendicular to the image receptor
Rationale: Dorsiflexion of the foot is necessary and the ball of the foot should be positioned perpendicular to the image receptor to allow the tangential beam to skim the part.
