Diffuse optical tomography to monitor the photocoagulation front during interstitial photothermal therapy: Numerical simulations and measurements in tissue-simulating phantoms
(De Gruyter, 2014-08-06)Near-infrared interstitial photothermal therapy (PTT) is currently undergoing clinical trials as an alternative to watchful waiting or radical treatments in patients with low/intermediate-risk focal prostate cancer. ... -
Digital signal processor-based real-time optical Doppler tomography system
(SPIE, the international society for optics and photonics, 2004-05-01)We present a real-time data-processing and display unit, based on a custom-designed digital signal processor (DSP) module for imaging tissue structure and Doppler blood flow. The DSP module is incorporated into a conventional ... -
Hybrid positron detection and optical coherence tomography system: Design, calibration, and experimental validation with rabbit atherosclerotic models
(SPIE, the international society for optics and photonics, 2005-07-01)We evaluate the performance of our novel hybrid optical coherence tomography (OCT) and scintillating probe, demonstrate simultaneous OCT imaging and scintillating detection, and validate the system using an atherosclerotic ... -
In vivo trans-rectal ultrasound-coupled near-infrared optical tomography of intact normal canine prostate
(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
(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 ... -
Toward transduodenal diffuse optical tomography of proximal pancreas
(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
(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
(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 ... -
Transrectal ultrasound-integrated spectral optical tomography of hypoxic progression of a regressing tumor in a canine prostate
(SAGE Publications, 2011-12-01)The objective of this study was to evaluate if transrectal optical tomography implemented at three wavelength bands for spectral detection could monitor changes of the hemoglobin oxygen saturation (SₜO₂) in addition to ...
