组织变形、成像探头和手术器械的跟踪是术中手术引导的一个组成部分。虽然最近引入的形状实例化提供了实时跟踪 3D 解剖结构的系统框架，但所需成像位置的偏差可能会影响预测形状的准确性。为了检查指定图像平面对此类误差的敏感性，我们在本文中引入了一种新的可实例性指数，用于在使用此类扫描平面跟踪解剖结构和介入设备时提供内在的鲁棒性水平。索引的优化应用于 3D 解剖重建和术中成像设备的定位。结果显示在实时 3D 形状实例化和成像导管跟踪的详细模型实验中。
The tracking of tissue deformation, imaging probes and surgical instruments is an integral part of intra-operative surgical guidance. While the recent introduction of shape instantiation provides a systematic framework for tracking 3D anatomy in real-time, deviations to the desired imaging location can affect the accuracy of the predicted shape. To examine the sensitivity of the prescribed image planes to such errors, we introduce in this paper a new Instantiability Index for providing the intrinsic level of robustness while using such scan planes for the tracking of anatomy and interventional devices. Optimisation of the Index is applied to 3D anatomical reconstruction and the localisation of an intraoperative imaging device. Results are shown on detailed phantom experiments for both real-time 3D shape instantiation and imaging catheter tracking.
