The present invention provides video and audio assisted surgical techniques and methods. Novel features of the techniques and methods provided by the present invention include presenting a surgeon with a video compilation that displays an endoscopic-camera derived image, a reconstructed view of the surgical field (including fiducial markers indicative of anatomical locations on or in the patient), and / or a real-time video image of the patient. The real-time image can be obtained either with the video camera that is part of the image localized endoscope or with an image localized video camera without an endoscope, or both. In certain other embodiments, the methods of the present invention include the use of anatomical atlases related to pre-operative generated images derived from three-dimensional reconstructed CT, MRI, x-ray, or fluoroscopy. Images can furthermore be obtained from pre-operative imaging and spacial shifting of anatomical structures may be identified by intraoperative imaging and appropriate correction performed.

The invention relates to a method of position detection in X-ray imaging, and to a device for carrying out such a method by means of an X-ray apparatus, a detector device, including at least two detector elements, and an indicator device. The exact association of the X-ray image with the object imaged is very important notably for intraoperative imaging. Exact knowledge of the position and orientation of the components of the X-ray apparatus associated with the imaging system is required for this purpose. However, it is often problematic that the lines of sight of the position measuring system are obscured by attending staff or other apparatus. Therefore, in the device according to the invention the detector device is mounted on the X-ray apparatus and the indicator device is provided so as to be stationary on the object to be examined or stationary relative to the object to be examined. Also described is a method of position detection in X-ray imaging by means of such a device.

Intraoperative image(s) of a patient target site are generated by an intraoperative imaging system (e.g., ultrasound or X-ray). The intraoperative imaging system is tracked with respect to the patient target site and surgical instrument(s) (e.g., a pointer, endoscope or other intraoperative video or optical device). The intraoperative images, surgical instruments, and patient target site are registered into a common coordinate system. Spatial feature(s) of the patient target site are indicated on the images of the patient target site. Indicia relating the position and orientation of the surgical instrument(s) to the spatial feature(s) of the patient target site are projected on the images, with the indicia being used to correlate the position and orientation of the surgical instruments with respect to the target feature.

A method for generating an augmented reality image for supporting the adjustment of the position of a surgical instrument during sinus surgery comprising the steps of: selecting at least one of sinus cells, cavities and orifices of the sinus in a pre-operative image by marking them with at least one geometric primitive or tube shaped object; using real-time intra-operative imaging for displaying the operating field; determining the relative positions at least between the real-time imaging of the patient and the pre-operative image data; computing a virtual image corresponding to a real-time image comprising at least one marked geometric primitive or tube shaped object based on the determined relative positions; combining the virtual image and the real-time intraoperative image for visualization in an augmented reality image.

An imaging system includes a source and a detector that can be quickly and easily moved out of the way after scanning. During scanning, the actual paths that the source and detector travel are tracked, such as by an associated surgical navigation system tracking system. The actual locations of the source and detector during each x-ray image are used in the image reconstruction algorithm. Since the actual locations are used in the algorithm, the locations do not have to be as precisely controlled. In one embodiment, the source and detector are mounted proximate outer ends of first and second c-arm sections. The first and second c-arm sections are extendable to form a complete c-arm and retractable to a collapsed position when not in use. In the disclosed embodiment, the c-arm sections are mounted to a base or carriage under the patient support surface (such as the surgical table).
