Abstract

A system and method for displaying kinematic and kinetic information of a subject is provided. The system includes an image input stage for acquiring image data of the subject, a transformation stage for transforming the image data into three dimensional coordinates corresponding to one or more body segments of the subject, and an output data stage for calculating the kinematic and kinetic information of the subject from the three dimensional coordinates. The system can also include a user interface for displaying the calculated kinematic and kinetic information of the subject.

Claims

1. A system for displaying kinematic and kinetic information of a subject, comprising:

an image input stage for acquiring image data of the subject;

a transformation stage for transforming the image data into three dimensional coordinates corresponding to one or more body segments of the subject; and

an output data stage for calculating the kinematic and kinetic information of the subject from the three dimensional coordinates.

2. The system of claim 1, further comprising a user interface for displaying the calculated kinematic and kinetic information of the subject.

3. A method for displaying kinematic and kinetic information of a subject, said method comprising:

acquiring image data of the subject;

transforming the image data into three dimensional coordinates corresponding to one or more body segments of the subject; and

calculating the kinematic and kinetic information of the subject from the three dimensional coordinates.
