All elastograms were evaluated for the lesion visibility, relativebrightness, and margin regularity and definition by using a four-point scale.
应用四点积分标准评价所有弹性图像的病变可视性、相对明亮度、边缘规则性和有限性。

As relative orientations change, the brightness of reflections may also change, sometimes suddenly.
随着相对方位的变化，反射光亮度也随之变化，有时亮度的变化是突然发生的。

This isn't a liable solution, because when the billboards turn to follow the camera, their Angle relative to the light source will change, and so will their brightness.
