影像引导手术所需的配准技术的验证是一个重要的问题，在文献中很少受到关注。在这篇文章中，我们解决了一个具有挑战性的问题，即建立一个可靠的金标准来评估外科2D/3D注册的准确性。我们设计了一个带有基准标记的身体腰椎模型，并在3D CT和MR图像与18个2D X光图像之间建立了高度精确的对应关系。对于CT到X射线的配准，预期的目标配准误差在0.2 mm量级，对于MR到X射线的配准，预期的靶配准误差在0.3 mm量级。因此，根据作者的要求提供的金标准图像对于测试图像引导外科手术中的2D/3D配准方法是有用的。
Validation of registration techniques needed for image-guided surgery is an important problem, which received little attention in the literature. In this paper we address the challenging problem of generation of a reliable gold standard for evaluating the accuracy of surgical 2D/3D registrations. We have devised a cadaveric lumbar spine phantom with fiducial markers and established highly accurate correspondence between 3D CT and MR images and 18 2D X-ray images. The expected target registration errors are in the order of 0.2 mm for CT to X-ray registration and in the order of 0.3 mm for MR to X-ray registration. As such, the gold standard images, which are available on request from the authors, are useful for testing 2D/3D registration methods in image guided surgery.
