Computer-Assisted Joint Replacement (hip and knee)
Pathologies in the joint regions are common especially among elderly patients; they are caused, in many cases, by shocks applied on the cartilage layer cushioning between bones. The consequences of this deterioration can be serious and affect the proper function of the joint. Cases where hip and ...

Robots in Medical Applications
In the recent years, robotic modules with their associated algorithmic software emerged in the surgery rooms. Here, some of their applications will be reviewed. They are used for orthopedic, brain and cardiac surgeries. Remotely operated robot in the surgery room are surgeon-controlled robots who...

Registration of CT and X-ray
Registration is a phase of orthopedic surgeries in which a visualization system is called to support the surgeon. This system provides real time view of the surgery environment and the information from the CT imaging. Two different steps of registration are executed here: tracking system registra...

CT Segmentation in orthopedic surgery
CT image segmentation is a typical phase of orthopedic surgeries in which a visualization system is called to visually support the surgeon’s task. This system provides a real time view of the surgery environment, as well as information coming from the pre-op planning and from the CT. It enables h...

Bone segmentation in orthopedic surgery
Orthopedic surgeries are one of the most common surgeries in clinical practice. According to recent surveys, more than 300,000 hip replacement and 700,000 knee replacements are performed annually, with frequent treatment of other joints, e.g. shoulder and ankles. With figures on the rise, the bur...

Detection and quantification of bone cancer
Primary malignant tumor of the bone (osteosarcoma) is the most common bone tumor, representing 88% of all bone tumors with nearly 3,000 annual diagnosed cases in the United States. Despite the relative low occurrence of primary osteosarcoma (less than 1% of all tumors), secondary (metastatic) bon...

Point and surface registration in orthopedics
Orthopedic surgery is a branch of surgery concerned with treating the musculoskeletal system’s injuries and reconstruction. About half the population above the age of 50 suffer from some degree of osteoarthritis. According to the 2008 report of the American Academy of Orthopedic Surgery, the most...

Bones and Skeleton segmentation
Computed tomography (CT) is the most common 3D process used for bone imaging. This is due to the fact that simple thresholding is usually sufficient to identify the bone tissue, based on its higher attenuation of X-rays as compared to soft tissues. The representation of a tridimensional model out...
