REAL TIME 3-DIMENSIONAL BRACHYTHERAPY GUIDANCE SYSTEM

提出了一种用于开发实时的、3-3位的视频监控系统的技术。 基于三维超声的导引可视化系统 治疗前列腺癌的放射性植入物。系统 包括实时三维成像阵列并支持2D， 3D和虚拟现实可视化界面。目前的技术 经直肠超声引导下近距离放射治疗 不可接受的并发症比率。提议的技术的目的是 降低并发症发生率，提高局部控制率 通过优化种子植入过程中的可视化来提高成功率 超声引导下的近距离放射治疗。 拟议的商业应用：这项研究的结果可能 对前列腺癌的治疗有立竿见影的效果 更高剂量的辐射，定位更准确，更少 毒性/发病率较低。它将提供“看到”的能力 通过3D前列腺体积植入植入物一大群 患有局部疾病或手术风险较低的患者或 那些不想要开放手术的人是候选人。

A technique is proposed for the development of a real-time, 3- dimensional ultrasound-based visualization system for guidance of radioactive implants for treating prostate cancer. The system includes a real-time 3 dimensional imaging array and supporting 2D, 3D, and virtual reality visualization interfaces. Present techniques using transrectal ultrasound guidance for brachytherapy result in unacceptable rates of complication. The aim of the proposed technique is to reduce the complication rates and improve the local control rates by optimizing the visualization of seed implantation during ultrasound-guided brachytherapy. PROPOSED COMMERCIAL APPLICATION: The outcome of this research could be of immediate benefit in the treatment of prostate cancer using higher dose radiation with more accurate localization and fewer toxicities/less morbidity. It would provide the ability to "see through" the 3D prostate volume while placing implants A large group of patients with localized disease or who are poor surgical risks or who do not desire open surgery are candidates.
