Abstract
Intra-cardiac 3D ultrasound imaging has enabled new minimally invasive procedures. Its narrow field of view, however, limits its efficacy in guiding beating heart procedures where geometrically complex and spatially extended moving anatomic structures are often involved. In this paper, we present a system that performs electrocardiograph gated 4D mosaicing and visualization of 3DUS volumes. Real-time operation is enabled by GPU implementation. The method is validated on phantom and porcine heart data.
摘要
心内三维超声成像推动了新型微创程序的发展。然而，其狭窄的视野限制了它在指导心脏跳动手术中的功效，因为这类手术常常涉及几何形状复杂且空间范围扩展的移动解剖结构。在本文中，我们展示了一种执行心电图门控的三维超声容积的四维拼接和可视化的系统。通过图形处理器（GPU）实现实现了实时操作。该方法在体模和猪心脏数据上得到了验证。
