Abstract
A reference marker system configured for use with a separate medical device can include a main body and a plurality of reference marker sites. The main body can have outer and inner surfaces and an overall geometry that interacts with a distinctive feature on the separate medical device. The main body can removably couple to the separate medical device along its inner surface at a specific orientation based on the distinctive feature. The reference marker sites can be coupled to the outer surface and configured to host reference markers suitable for use with a separate augmented reality system. The reference marker sites can be distributed across the outer surface at fixed positions relative to each other to form an asymmetrical fixed positional arrangement, which can be known for a medical procedure using the separate medical device without requiring any reference marker calibration based on the specific orientation.
