Order type dataset analysis for fiducial markers
Data in Brief, 2018 Order Type (OT) describes a point set avoiding the use of metric information. We show that OT is a descriptor which is invariant to Euclidean geometric transformations, change of scale and perspective projection. In this paper we provide the data related to the application of Order Type with sets of 5, 6, 7, and 8 points to build fiducial markers.

Tumor track seeding: A new complication of fiducial marker insertion
Radiology Case Reports, 2014 In the United States, lung cancer is the leading cause of cancer-related death. Candidates for tumor ablation using CyberKnife® require fiducial placement in or near the target tumor to achieve precision.
