In vivo trans-rectal ultrasound-coupled near-infrared optical tomography of intact normal canine prostate
Piao, Daqing; Jiang, Zhen; Bartels, Kenneth E.; Reed Holyoak, G; Ritchey, Jerry W.; Xu, Guan; Bunting, Charles F.; Slobodov, Gennady (World Scientific Publishing, 2009-07-01)This is the first tomography-presentation of the optical properties of a normal canine prostate, in vivo, in its native intact environment in the pelvic canal. The imaging was performed by trans-rectal near-infrared (NIR) ... -
In vivo trans-rectal ultrasound-coupled optical tomography of a transmissible venereal tumor model in the canine pelvic canal
Jiang, Zhen; Holyoak, G. Reed; Bartels, Kenneth E.; Ritchey, Jerry W.; Xu, Guan; Bunting, Charles F.; Slobodov, Gennady; Piao, Daqing (SPIE, the international society for optics and photonics, 2009-05-01)In vivo trans-rectal near-infrared (NIR) optical tomography was performed concurrently with, albeit reconstructed without spatial a prior of, trans-rectal ultrasound (US) on transmissible venereal tumor (TVT) developed as ... -
The utility of direct-current as compared to frequency domain measurements in spectrally-constrained diffuse optical tomography toward cancer imaging
Xu, Guan; Piao, Daqing; Dehghani, Hamid (SAGE Publications, 2011-10-01)This work investigates, by means of analytical and simulation studies, the performance of spectrally-constrained image reconstruction in Continuous-Wave or Direct-Current (DC) and Frequency Domain (FD) near-infrared optical ... -
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 ...
