Area of Science:

  • Biomedical Optics
  • Medical Imaging
  • Biophysics

Background:

  • Current imaging techniques for bone and joint structures have limitations in providing detailed volumetric information.
  • Diffuse optical imaging offers potential for non-invasive tissue characterization.

Purpose of the Study:

  • To develop and demonstrate a full three-dimensional (3D) volumetric reconstruction method for absorption images of in vitro and in vivo bones and joints.
  • To evaluate the capability of near-infrared tomographic measurements for detailed bone and joint imaging.

Main Methods:

  • Utilized a Clemson multichannel diffuse optical imager for imaging experiments.
  • Conducted experiments on human finger and chicken bones embedded in scattering media.
  • Employed a 3D finite element based reconstruction algorithm to recover volumetric optical images.
