Brief Summary

To test the feasibility and to evaluate the accuracy of upper and lower extremity abnormality evaluation using the Multitom Rax x-ray system with 3D cone-beam imaging technology

Primary Objective: To assess the merit, usefulness, strength, and limitations of 3D cone-beam imaging for early assessment of upper and lower extremity abnormalities observed in patients referred for radiographic imaging at The University Hospital.

Secondary Objective:  To accumulate raw projection data of upper and lower extremity, in cases without abnormalities as well as in cases with presence of abnormalities, to enable the development of advanced 3D image reconstruction algorithms that may further improve the image quality without added radiation exposure and increase the range of applications of 3D cone-beam imaging with the Multitom Rax.

Tertiary Objective: To obtain data for thorough assessment of effective radiation dose



Inclusion Criteria

For both groups:

1. Subjects are 18 years of age and older

Additional inclusion criteria for patient group:

2. X-ray/radiographic study ordered for upper or lower extremity, including foot, ankle, leg, knee, elbow, forearm, wrist, or hand, based on clinical suspicion of abnormality



Exclusion Criteria

1. Unable to provide informed consent

2. Pregnant subjects

3. Any staff members who report directly to the PI or who report to someone who reports directly to the PI. 

Additional exclusion criteria for patient group:

4. Patients with isolated clinical abnormality of the proximal femur, proximal humerus, scapula, rib, or clavicle
