A radiograph is acquired using a source-to-image distance (SID) of 40 inches. If the radiograph is repeated using the same exposure factors, but the SID increases to 60 inches, the receptor exposure will:

A patient presents to the radiology department for a foot radiograph and upon assessment of the patient, the technologist sees that the patient has stepped on a nail and the nail is still sticking out of the plantar surface of the foot approximately two inches. This nail will create object-to-image distance (OID) that cannot be avoided on an anteroposterior (AP) foot radiograph. What steps should the radiographer take to prevent the size distortion that would be created by the long OID?
