Abstract
Mobile C-arms are an everyday tool to acquire X-ray images in the operating room during surgery. The Camera Augmented Mobile C-arm (CamC) system augments a regular mobile C-arm by a video camera for X-ray and video image overlay. Thanks to the mirror construction and one time calibration of the device, the acquired X-ray images are co-registered with the video images without any further calibration or registration during the intervention. The CamC system can support a wide range of potential clinical applications, such as needle guidance, interlocking of intramedullary nails, and pedicle screw placement.

| As an extension the camera augmented mobile c-arm system by Navab et al. 1999 we developed a multi-view system which offers 3D navigation during trauma surgery and orthopedic procedures. We use an additional video camera in an orthogonal arrangement to the first video camera and a minimum of two X-ray images. |

| Standard X-ray images have a narrow field of view and can not visualize the entire long bone on a single image. We propose a novel method to generate panoramic X-ray images by using the Camera Augmented Mobile C-arm. This advanced mobile C-arm system can register the X-ray image with an optical image by construction, which facilitates the generation of panoramic X-ray images based on first stitching the optical images and then embedding the X-ray images. |
