Likewise, a display element can be illuminated in the selected peripheral locators upon selecting the peripheral locators. Compute point indicators also effectively self-synchronize multiple data flows without external control. The method involves introducing a coordinate system into a C-arm image, and applying intensity-based 2D3D registration without segmentation to the coordinate system C-arm image and an image or known model of the coordinate system, wherein the intensity-based 2D3D registration yields the C-arm pose.
