Fig. 2. Depending on the location of the X-ray generator, the parts of the body exposed to scattered X-rays vary. When an image is taken with the X-ray generator (red circle) positioned below (A), more scattered radiation is generated in the lower extremities of the physician and medical staff [
9]. When a lateral view is taken (B), more scattered radiation is generated on the side where the X-ray generator is located [
14]. If the flat panel detector is positioned downwards to obtain an image (C), a large amount of scattered radiation is generated to the upper body, neck, and head. The red circle is X-ray generator.
