Consideration of Lens of the Eye Protection during Mammography with the Eyelid and the Face Guard

Purpose In 2011, the International Commissionon Radiological Protection (ICRP) recommended reducing threshold dose for lens. Therefore, it is important to reduce lens exposure in medical exposures. a cranio-caudal (CC) view of mammography, patient' s receives scattered radiation. this study, we investigated scatter around during mammography and reviewed simple easy protection methods Methods Optically stimulated luminescence (OSL) dosimeters were placed front device obtain radiation intensity distribution. The human phantom was same way as CC positioning, BR-12 phantoms with thickness 40 mm on FPD. Then, measured using an OSL dosimeter. order confirm change by face guard (FG) eyelid, compared under conditions presence FG adipose tissue about 1 thick assuming eyelid. Results Scatter decreased FG. When installed, reduced 33%, when pasted dosimeter, 29%. Conclusion This study suggested that eye closure effective exposure. future, would like expect further protective effects increasing reviewing materials.
