Analysis of causes of X-ray artifact Liu Liang-thick X-ray artifact is a more common phenomenon. Due to the physical and chemical properties of x-ray film and improper use of custody, etc., often appear different artifacts. These artifacts are generally divided into two categories: black artifacts and white artifacts. Black artifact is a high-density image (optical density) in physics. X-ray film partial silver ion exposure after development ...
