Bowyer et at. presents a review of active constrains in a generalized active constraint implementation framework; by defining, evaluating and enforcing these constraints. Geometry based definitions can simple as single point, and more complex e.g. a parametric 3D surface. The evaluation is made by computing metrics to and from the active constraint, to the constrained…

Zheng, Jian-Qing, Xiao-Yun Zhou, Celia Riga, and Guang-Zhong Yang  International Conference on Robotics and Automation (ICRA), pp. 8747-8753. IEEE, 2019. DOI: https://doi.org/10.1109/ICRA.2019.8793918 The current standard of intra-operative navigation during Fenestrated Endovascular Aortic Repair (FEVAR) calls for the need of 3D alignments between inserted devices and aortic branches. The navigation commonly via 2D fluoroscopic images, lacks…
