Morishima Y, et al. - This study was set up with the aim to assess a new lead-shielding device and separately attached additional filters (1.0-, 2.0-, and 3.0-mm Al filters and a 0.5-mm Cu filter) during videofluoroscopic swallowing study (VFSS) to reduce the patient’s entrance skin dose (ESD). The physicians demonstrated that the combined VFSS Shielding Box and filters could effectively reduce the physician’s and patient’s radiation doses.
