Abstract: A movement detection device for detecting quantitatively the movement of a patient by capturing images of a deformable surface having an indicator associated therewith, the indicator being responsive to changes in a profile of the deformable surface. The captured images are analysed to derive a patient movement from the changes in the profile of the deformable surface. For example, the movement detection device of the invention can detect the sense (translational and/or rotational) and magnitude of the patient movement. This information may enable real time adjustment of the treatment signal or indeed provide a safety facility whereby should there be detection that the patent has moved or has moved beyond certain parameters, the device that is observing or treating the patent is switched off.

Abstract: The present application relates to a system (10) for anatomical reduction of bone fractures in which first and second manipulators (12, 14), and optionally a third manipulator (16), are attached to fragments of the fracture to be reduced by percutaneous attachment devices such as Schanz pins. An underlying processing system determines, from one or more medical images of the fracture, manipulations such as rotations and translations of the bone fragments required to correctly reposition and align the fragments for optimum healing of the fracture. The processing system provides motion reference signals (position, speed, acceleration and force) for a controller, which in turn causes the first, second and third manipulators (12, 14, 16) to effect the calculated manipulations.
