结肠息肉的虚拟可视化检查系统

摘要

The virtual colonoscopy, virtual flattening and virtual splitting method are enhanced by the GPGPU model.The novel virtual eversion method is integrated for fast polyp detection.The experimental result showed that the system and various visualization methods can represent the colon inner-surface clearly and exactly, supporting real-time man-machineinteraction.The proposed system is promising in human gastrointestinal cancer and polyp inspection.%根据GPGPU原理,用虚拟内窥镜、虚拟展平和虚拟切开并结合虚拟外翻技术,设计了一种用于快速辅助结肠息肉检查的诊断系统.实验结果表明,该系统的各种虚拟可视化方法能够清晰准确地显示结肠内壁表面,能提供实时的人机交互操作,可以应用于快速高效的人体胃肠道早期癌症和息肉的检查.
