Fiducials detection for movement estimation and guidance

Abstract

An X-ray imaging system includes an X-ray radiation source, an X-ray detector, and a C-arm having the X-ray radiation source disposed on a first end and the X-ray detector disposed on a second end opposite the first end. The X-ray imaging system is configured to translate the C-arm in multiple different directions and to rotate the C-arm about multiple different axes. The X-ray imaging system includes an optical camera configured to capture image data of a position of the C-arm relative to a location. The X-ray imaging system includes a controller configured to receive the image data from the optical camera and to utilize machine vision both to determine an initial position of the C-arm relative to the location and to navigate a return of the C-arm to the initial position when the C-arm has been moved from the initial position based on the image data.
