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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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) ...
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 ...
