摘要：
Disclosed herein are systems and methods for determining alignment angles between a first prosthetic component and a second prosthetic component that are joinable together in a fixed orientation relative to each other, wherein the fixed orientation includes a first angle and optionally also a second angle that are perpendicular to each other, and wherein the first and/or second angles are selectable from a range of angles to provide a desired fixed orientation between the two prosthetic components. The system includes a magnet fixedly coupled to the first prosthetic component and one or more magnetic intensity sensors configured to be coupled to the second prosthetic component in a fixed orientation relative to the second prosthetic component such that the sensors are operable to sense a magnetic field of the magnet and produce an output signal in response to the strength of the sensed magnetic field. The system can include a processor operable to receive the output signals from the sensors and determine the first and/or second angles.
