A low-cost needle-based single-fiber reflectance spectroscopy method to probe scattering changes associated with mineralization in intervertebral discs in chondrodystrophoid canine species - A pilot study
(De Gruyter, 2012-05-01)Background and objectives: Intervertebral disc herniation is a common disease in chondrodystrophic dogs, and a similar neurologic condition also occurs in humans. Percutaneous laser disc ablation (PLDA) is a minimally ... -
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 ... -
On the stress-induced photon emission from organism: I, will the scattering-limited delay affect the temporal course?
(Springer Nature, 2020-08-27)Much remains to be identified for the temporal course of stress-induced photon emission (PE) from organism following stress of various types including but not limited to light. Induced PE concerns surface light emission ... -
Portable near-infrared diffusive light imager for breast cancer detection
(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 ... -
Self calibration iso-pathlength point in cylindrical tissue geometry: Solution of steady-state photon diffusion based on the extrapolated zero-boundary
(Optica Publishing Group, 2018-12-21)Near-infrared optical techniques permit tissue diagnosis by surface measurement. However, the geometrical shape of this interface profiles the intensity of the surface measurement, which is found to have an iso-pathlength ... -
Towards non-contact glucose sensing in aqueous turbid medium at ∼1.1 meters distance
(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
(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 ...
