Title: X-RAY SCALING DEVICES, SYSTEMS, AND METHODS
Abstract:
Various systems, devices, and methods for facilitating efficient anatomical registration in surgical navigation are disclosed. Such systems and devices can have a data collection unit and a scaling device. The scaling device has a main body having an anatomical registration feature defined therein and at least one scaling marker pathway that is selectively oriented with respect to the anatomical registration feature to facilitate repeatable gross placement of a scaling marker relative to a selected anatomical feature. The scaling marker is selectively displaceable along a scaling marker pathway about and between a first end and a second end thereof to fine-tune scaling marker placement prior to image capture.
