光学体表引导放疗技术的临床应用

Clinical application of surface guided radiotherapy

光学体表引导放疗技术采用三维体表成像原理实时获取体表图像,通过与参考图像比较,可完成治疗前位置验证、治疗中实时监控和门控治疗等功能。它是一种无创无辐射的技术,其临床应用主要包括颅内、头颈、胸腹部、乳腺、四肢以及儿童肿瘤的治疗,应用研究进展包括更少体表标记、更少束缚固定、更安全碰撞预测和更准确实时追踪方面。

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.
