When there are brightly painted walls or reflective objects in the environment around the scanner, the scanner may have trouble seeing the top of the turntable. Which looks like this:

When the scanner cannot see the turntable, it can lose the person on the turntable which can cause a subject loss error to be displayed. Especially when the person is turned sideways toward the scanning tower. There are a few different work arounds to prevent this issue.
