In this paper, we propose a novel method to generate panoramic X-ray images intra-operatively by using the previously introduced camera augmented mobile C-arm by Navab et al. [1]. This advanced mobile C-arm system acquires registered X-ray and optical images by construction, which facilitates the generation of panoramic X-ray images based on the motion estimation of the X-ray source. Visual mar...

Accurate 3D reconstruction of the surgical scene is important in intra-operative guidance. Existing methods are often based on the assumption that the camera is static or the tissue is deforming with periodic motion. In minimally invasive surgery, these assumptions do not always hold due to free-form tissue deformation induced by instrumenttissue interaction and camera motion required for conti...

We evaluated 30 patients with cervical myelopathy before and after decompressive surgery and compared them with 42 healthy controls. All were asked to grip and release their fingers as rapidly as possible for 15 seconds. Films recorded with a digital camera were divided into three files of five seconds each. Three doctors independently counted the number of grip and release cycles in a blinded ...

PURPOSE To develop an intraoperative multimodal imaging system (IMIS) for surgical guidance, combining gamma ray scintigraphy with a video camera system for simultaneous real-time visible and near infrared fluorescence (NIRf) imaging. METHODS The gamma camera component has been tested in a pilot human study for intraoperative SLN biopsy in melanoma patients. To characterize the optical compon...
