    TLDR The new therapy effectively targets brain tumors while minimizing damage to healthy tissue.
    The study introduced a "three-dimensional moving field radiation therapy" for brain tumors, which involved multi-plane rotation while maintaining the same isocenter to improve spatial dose distribution. This method aimed to deliver high doses to tumors while sparing normal tissues and could be implemented with existing equipment for conventional rotation radiation therapy. It was found to be superior to one-plane rotation radiation therapy in tests using physical and chemical phantoms, as well as a biological model with tumor cells. In the treatment of six brain tumors with total air doses of 50-60 Gy, there were no observed cases of hair loss or radiation necrosis.
