China3D printingNet, May 21, researchers from Yamaguchi University in Japan asked three lung cancer patients to participate in a study that evaluated a dynamic motion phantom system that can perform patient-specific quality assurance using a tumor tracking system, which can be reproduced The patient’s anatomy and 3D tumor movement. Respiratory gated radiation therapy. They reported on “a novel dynamic robotic motion phantom system that can ensure patient-specific quality in real-time tumor tracking radiotherapy.”
When using stereotactic radiotherapy (SBRT) for cancer treatment, tumor movement in the abdominal or thoracic region during breathing may cause precise dose delivery problems.You need a larger internal margin or IM to cover the geometric changes that occur during free breathing, but this repair method will cause another problem
