Abstract
The scattered radiation protector for mobile x-ray systems, Creative Valuable
Protector-2, has been recently developed. However, there have been no studies
investigating the effects of this device. We aim to investigate the effects of the
scattered radiation protector on the equivalent doses from scattered radiation
delivered to radiosensitive organs while simulating spine surgery using a
C-arm fluoroscope. Chest and rando phantoms were used to simulate a patient
and a surgeon in this study. The equivalent dose from scattered radiation to
radiosensitive organs was measured in four different situations according to
the use of the scattered radiation protector and the C-arm configuration. To
compare the quality of the images with and without the scattered radiation
protector, an acryl step phantom with five steps was used, and the contrast
resolution of each step was calculated. The equivalent dose from the scattered
radiation to the surgeon’s eye, thyroid, and gonad decreased significantly
