A modular fluoro-navigation instrument including a base made of a substantially radiotransparent material. The base is intended to be rigidly secured to a patient's bone and a tracker rigidly attachable to the base. The instrument has a registration phantom separate from the tracker which includes a plurality of radiopaque fiducials. The base and the registration phantom includes respective attachment members for reproducibly attaching the registration phantom to the base.

Modular fluoro-navigation instrument

A fluoro-navigation system for navigating a tool relative to a medical image. The system includes a motorized X-ray imaging system for acquiring a plurality of images of a region of interest of a patient, the position of each image being known. Also included is a localization system, a registration phantom with a plurality of radiopaque fiducials, a tracker for being tracked by the localization system, a processor for receiving the plurality of images and for reconstructing a 3D medical image from the images using radiopaque fiducials visible in the plurality of images. Also included is base made of a substantially radiotransparent material, to be rigidly secured to a patient's bone and having a reproducible fixation system for attaching the registration phantom and/or tracker.

Fluoro-navigation system for navigating a tool relative to a medical image

The invention relates to a device for minimally invasive attachment of a tracker () and/or a registration phantom () to a patient's bone, comprising a base () made of a substantially radiotransparent material, characterized in that the base () comprises:

Device for minimally invasive attachment of a tracker and/or a registration phantom to a patient's bone

The invention relates to a method for determining a trajectory of a motorized X-ray imaging system for acquiring images of a patient to whom a phantom comprising radiopaque fiducials having a known spatial arrangement has been attached so as to be visible on at least one 2D image of a body region of interest acquired by the X-ray imaging system by acquiring one first 2D image of the phantom by the X-ray imaging system in a given position; detecting the fiducials of the phantom in the acquired first image; based on the detected fiducials, determining the position of the phantom in a referential of the X-ray imaging system; determining a set of positions of the X-ray imaging system configured to acquire a set of 2D X-ray images of the region of interest such that the set of 2D X-ray images complies with at least one imposed requirement on the position of the phantom relative to a part of the set of images and combining the set of determined positions to determine a trajectory of the X-ray imaging system with respect to the position of the phantom.
