Flat-panel-based X-ray cone-beam computed tomography (CBCT) can provide images of high utility in medical applications such as image-guided surgery and radiotherapy by offering location and contrast information concerning the target and surrounding region. A potential issue in these applications of CBCT is the imaging dose involved because repeated scans are necessary in the image-guided procedures...
Mobile C-arm is an essential tool in everyday trauma and orthopedics surgery. Minimally invasive solutions, based on X-ray imaging and coregistered external navigation created a lot of interest within the surgical community and started to replace the traditional open surgery for many procedures. These solutions usually increase the accuracy and reduce the trauma. In general, they introduce new hardware...
Real-time visualization plays an important role in medical imaging applications such as image-guided surgery, surgical simulation and medical education. For the real-time visualization and the simultaneous overlay of 3D triangulated objects onto live recordings of patient data gathered with fast imaging devices (e.g. from the beating heart) it is essential that the number of triangles used for displaying...
We presented a set of methods for registration of preoperative CT data set to intra-operative X-ray images in minimally invasive image-guided spinal surgery. The registration procedure is composed of two steps. Firstly, a rough registration using a variant form of Iterative Closest Point algorithm is adopted to get an overlapped area. Secondly, the fine registration is performed based on gradient...
