    • Portable near-infrared diffusive light imager for breast cancer detection 

      Chen, Nan Guang; Huang, Minming; Xia, Hongjun; Piao, Daqing; Cronin, Edward; Zhu, Quing (SPIE, the international society for optics and photonics, 2004-02-03)
      We present a frequency-domain near-infrared optical tomography system designed for breast cancer detection, in conjunction, with conventional ultrasound. It features fast optical switching, threewavelength excitations, and ...

    • 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 ...

    • 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 ...
