Quizplus · Accepted Answer

In order to obtain a properly positioned lateral facial bones projection, the chin must be adjusted so that the infraorbital-meatal line (IOML) is perpendicular to the front edge of the image receptor (IR). This helps to ensure that the facial bones are parallel to the IR and that there is no distortion of the anatomy.
