Image Processing for Orthopedic Surgery
Orthopedic surgeons can now benefit from the use of a mature set of computer vision and image processing tools for patient-specific measurement, navigation, surgical simulation, surface reconstruction, and implant design. These techniques are a breakthrough in the field of orthopedics, enabling to improve treatment, recovery times, surgery outcomes and the quality of life of patients.
Bones and Skeleton Segmentation
RSIP Vision suggests an automatic segmentation procedure based on iterative binarization of bone tissues density, as observed in Computed Tomography (CT), the most common 3D process used for bone imaging. This method is particularly fast, regardless of whether contrast was used in the CT scans. In fact, images taken with contrast generally display blood with an intensity which is similar to bone; our technique is able to overcome this challenge and to deliver a fast and satisfying bones segmentation and skeleton segmentation solution to our client.

Point and Surface Registration
Point and surface registration enable computer vision and image processing to improve surgical orthopedy practices and affect surgery outcome recovery. Bringing point and surface registration in the field of orthopedics, computer vision and image processing hold the potential to improve surgical practices and affect surgery outcome to favor the benefit of patients and fast recovery. Measurement accuracy (within less than 1 mm) is a strict constraint to computer-vision-based algorithms. Read more...
Anatomical Reconstruction with Sparse Set of Points
Advance navigation techniques in orthopedic surgery allow to construct 3D models of patients’ anatomical parts by matching a surface to an acquired set of data points. As an alternative to costly imaging procedures, ultrasound or fluoroscopic scan can be performed with much reduced costs and hazards. A set of surface points marked by the technician or physician forms then an initial sparse set for anatomical surface reconstruction. Here we show how RSIP Vision's engineers overcome the challenge of using a sparse set of points to accurately reconstruct a complex 3d surface. Read More
Robots in Medicine and Surgery
Machine Vision and Robotic algorithms are extensively used in solutions enabling surgical procedures and other medical applications. The robot's hand being more precise than the surgeon, more and more surgeries are performed by properly equipped surgical robots. Besides the details of medical robotics applications, this article discusses also other medical systems, in particular Virtual Reality in medicine, by which it is possible to develop a simulator for complex and risky surgeries like brain surgeries.
