Because most of the intraluminal tumors have invasive growth and irregular general shapes, the radiation therapy is applied while causing one-time or permanent damage to normal tissues and organs, even at the expense of some important organs. There are some protective devices made of lead plates or stainless steel packaging lead plates in clinical work at present, but lead is toxic and is not safe as a clinical protective material. In addition, these protective devices cannot effectively protect tumors at different positions in the body, and have different shapes, sizes and shapes, so that the tumors cannot be completely irradiated with lethal radiation, and normal tissues beside the tumors are also damaged because the normal tissues cannot be effectively protected.
