The goal of this work is to provide useful information about arthritic joints using a combination of light and ultrasound. Both light and sound have the advantages of being noninvasive, nontoxic, and non-ionizing. Light has the advantage of generating a spectroscopic view of a specific volume of soft tissue. The disadvantage of imaging with light in tissue is the poor resolution in scattering media while the disadvantage of imaging with ultrasound is that there is poor contrast imaging contrast in soft tissue. To mitigate these disadvantages the use of an Acoustic Photonic Imaging (API) system is employed. Modeling the microscopic physical changes that are produced from the acoustic sources in the soft joint tissue will provide details on the changes in index of refraction. These changes in index of refraction can then be used as lens to image the surface roughness of the arthritic joint.
