Abstract: A surgical system includes a surgical tool associated with a virtual haptic interaction point such that movement of the virtual haptic interaction point corresponds to movement of the surgical tool. The surgical system further includes a processing circuit to establish a virtual entry boundary and activate a haptic object, which constrains the surgical tool after the haptic interaction point crosses the virtual entry boundary.

Abstract: An imaging system includes a radiation source, a detector fixed to the radiation source such that the radiation source and detector form a hand-held imaging device configured to acquire image data, and a navigation system configured to track a pose of the hand-held imaging device.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for inertially tracked objects with a kinematic coupling. A tracked pose of a first inertial measurement unit (IMU) is determined, wherein the first IMU is mounted to a first object. The tracked pose of the first IMU is reset while the first object is in a first reproducible reference pose with a second object.

Abstract: A fiber optic tracking system for tracking substantially rigid object(s) is described. The fiber optic tracking system includes a light source, an optical fiber having a sensing component configured to modify optical signals from the light source, the optical fiber being configured to attach to the substantially rigid object, a detection unit arranged to receive the modified optical signals from the sensing component, and a calculation unit configured to determine a pose of the substantially rigid object in six degrees of freedom based on the modified optical signals.
