12. The method of claim 11 , wherein the registration process comprises a registration scan by the imaging system.

13. The method of claim 12 , wherein the field of view of the imaging system for the registration scan captures data indicative of the first body, the second body, and the object.

14. A system for imaging a subject having a first body and a second body, the system comprising:

a scanner configured to capture a kinematic set of scan data of the subject for multiple kinematic positions of the first body, the subject being positioned in the scanner such that the first body is disposed outside of a field of view of the scanner and such that the second body is disposed within the field of view;

an imaging proxy comprising a coupler configured for rigid attachment of the imaging proxy to the first body, and further comprising an extension connected to the coupler and spaced from the first body for disposition within the field of view and detection by the scanner such that the kinematic set of scan data is indicative of a position of the extension within the field of view, the extension being shaped to convey orientation information; and

a processor configured to calculate, based on the kinematic set of scan data and a positional relationship between the first body and the extension, a kinematic relationship of the first body relative to the second body;

wherein the scanner is further configured to capture registration scan data indicative of the positional relationship between the first body and the extension.

15. The system of claim 14 , further comprising a body manipulation apparatus configured to move the first body, the second body, or both the first body and the second body.

16. The system of claim 14 , wherein the imaging proxy comprises an adjustable connector to establish a spacing between the extension and the coupler.

17. The system of claim 14 , wherein the imaging proxy comprises a riser disposed between the coupler and the extension, wherein a height of the riser is adjustable to establish an offset of the coupler and the extension.

18. The system of claim 14 , wherein:

the extension is a first extension of the imaging proxy;

the imaging proxy comprises a second extension; and

the first and second extensions are oriented at respective angles relative to the coupler.

19. The system of claim 18 , wherein the first and second extensions are disposed in a V-shaped arrangement.

20. The system of claim 18 , wherein the imaging proxy comprises a mounting block to which the first and second extensions are attached.

22. The system of claim 14 , wherein the scanner is configured to capture data using an ultrasound technique, a computed tomography (CT) technique, a fluoroscopy technique, an X-ray technique, a magnetic resonance imaging (MRI) technique, an optical technique, an infrared technique, a magnetic tracking technique, or combinations thereof.

23. A method comprising:

disposing an object relative to a body such that the object acts as an imaging proxy for the body;

establishing a positional relationship between the body and the object;

after establishing the positional relationship between the body and the object, positioning the body and the object relative to an imaging system such that an extension of the object is disposed within a field of view of the imaging system and such that the body is disposed outside the field of view, the extension being oriented at an angle relative to the body; and

after positioning the subject in the imaging system such that the body is disposed outside the field of view, capturing, by the imaging system, a kinematic set of data indicative of the extension; and

calculating, by a processor, using the established positional relationship between the body and the object, a kinematic relationship of the body based on the captured kinematic set of data.

24. The method of claim 23 , wherein:
