Real-time 3D ultrasound (3DUS) imaging offers improved spatial orientation information relative to 2D ultrasound. However, in order to improve its efficacy in guiding minimally invasive intra-cardiac procedures where real-time visual feedback of an instrument tip location is crucial, 3DUS volume visualization alone is inadequate. This paper presents a set of enhanced visualization functionalities that are able to track the tip of an instrument in slice views at real-time. User study with porcine heart indicates a speedup of over 30% in task completion time.
实时三维超声(3DUS)成像相对于二维超声提供了更好的空间定位信息。然而,为了提高其在引导微创心脏内手术中的功效,在这类手术中器械尖端位置的实时视觉反馈至关重要,仅靠3DUS容积可视化是不够的。本文提出了一组增强的可视化功能,能够在切片视图中实时跟踪器械尖端。对猪心脏进行的用户研究表明,任务完成时间加快了30%以上。
