The operation or maintenance of any X-ray, fluoroscopic, or other equipment or apparatus employing roentgen rays, in the fitting of shoes or other footwear or in the viewing of bones in the feet is prohibited. This prohibition does not apply to any licensed physician, surgeon, *podiatrist, or any person practicing a licensed healing art, or any technician working under the direct and immediate supervision of such persons.

*Reviser's note: The term "podiatrist" was changed to "podiatric physician and surgeon" by 1990 c 147.
