    • Toward transduodenal diffuse optical tomography of proximal pancreas 

      Piao, Daqing; Bartels, Kenneth E.; Postier, Russell G.; Holyoak, G. Reed; Ritchey, Jerry W. (Optica Publishing Group, 2013-10-10)
      We demonstrate the feasibility of diffuse optical tomography (DOT) of the proximal pancreas by using optical applicator channels deployed longitudinally along the exterior surface of a duodenoscope. As the duodenum that ...

    • Towards non-contact glucose sensing in aqueous turbid medium at ∼1.1 meters distance 

      Piao, Daqing; O'Hara, John; Bukkapatnam, Satish; Ekin, Sabit (Institute of Electrical and Electronics Engineers (IEEE), 2020-07-30)
      This work demonstrates a non-contact diffuse reflectance approach with a working distance of ∼1.1 meters for the potential of glucose sensing. Non-contact diffuse reflectance over 1.1-1.3 μm was developed according to a ...

    • Trans-rectal ultrasound-coupled near-infrared optical tomography of the prostate. Part I: Simulation 

      Xu, Guan; Piao, Daqing; Musgrove, Cameron H.; Bunting, Charles F.; Dehghani, Hamid (Optica Publishing Group, 2008-10-15)
      We investigate the feasibility of trans-rectal optical tomography of the prostate using an endo-rectal near-infrared (NIR) applicator that is to be integrated with a trans-rectal ultrasound (TRUS) probe. Integration with ...

    • Trans-rectal ultrasound-coupled near-infrared optical tomography of the prostate. Part II: Experimental demonstration 

      Jiang, Zhen; Piao, Daqing; Xu, Guan; Ritchey, Jerry W.; Reed Holyoak, G; Bartels, Kenneth E.; Bunting, Charles F.; Slobodov, Gennady; Krasinki, Jerzy S. (Optica Publishing Group, 2008-10-15)
      We demonstrate trans-rectal optical tomography of the prostate using an endo-rectal near-infrared (NIR) applicator integrated with a transrectal ultrasound (TRUS) probe. The endo-rectal NIR applicator incorporated a design ...
