Aligning the central ray perpendicular to the Infraorbitomeatal Line (IOML) is the correct adjustment when a patient cannot hyperextend the neck for an SMV projection. This alignment ensures that the central ray is parallel to the IOML, compensating for the lack of neck extension and allowing for an optimal projection.
