Abstract
A method, system for registration of a bone, and a trackable element, used to obtain a mark point information which can be obtained from a certain operation performed by a distal end of a trackable element on a surface of the bone; obtain an image data of the bone through scanning the surface of the bone by a scanning device of the trackable element; and to perform a virtual reconstruction of the surface of the bone according to the obtained mark point information and an image data of the bone which is obtained in advance. As a result, a precise registration of the patient's physical space coordinate system and image space coordinate system can be achieved, during which only one operator is enough for completing the registration. Therefore, operations with high accuracy and convenience are ensured, which can significantly improve the registration efficiency, and the operating experience of operators.
