A patient stepped on a needle left in the carpet. Because only half the needle has been located and the patient has pain in the foot where the needle penetrated, it is suspected that the other half of the needle is still in the patient's foot. If the average technique for a lateral foot projection is 60 kVp at 75 mAs, what new technique should be used for this situation?

Lowering the kVp to 51 while maintaining the mAs at 75 will increase the contrast, making it easier to visualize the needle fragment in the soft tissue of the foot.
