Clinical application of surface guided radiotherapy / 中华放射肿瘤学杂志

ABSTRACT

By using optical surface guided radiotherapy technology, the principle of three-dimensional body surface imaging is employed to obtain body surface images in a real-time manner. By comparing with reference images, it can verify the position before treatment, and realize real-time monitoring and gated treatment during treatment. It is a non-invasive and non-radiation technology, which is mainly applied in the treatment of intracranial, head and neck, chest and abdomen, breast, extremities and pediatric tumors. The research progresses consist of four aspects including less body surface markers, less restraint fixation, safer collision prediction and more accurate real-time tracking.
