Single-fiber reflectance spectroscopy of isotropic-scattering medium: An analytic perspective to the ratio-of-remission in steady-state measurements
(MDPI, 2014-12-16)
Recent focused Monte Carlo and experimental studies on steady-state single-fiber reflectance spectroscopy (SfRS) from a biologically relevant scattering medium have revealed that, as the dimensionless reduced scattering ...
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. ...
In vivo percutaneous reflectance spectroscopy of fatty liver development in rats suggests that the elevation of the scattering power is an early indicator of hepatic steatosis
(World Scientific Publishing, 2018-05-11)
This study assessed whether there was a scattering spectral marker quantifiable by reflectance measurements that could indicate early development of hepatic steatosis in rats for potential applications to pre-procurement ...
The utility of direct-current as compared to frequency domain measurements in spectrally-constrained diffuse optical tomography toward cancer imaging
(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 ...
Which kind of and how much disruption to the symmetry of double-slit is necessary to produce the fringe pattern changes as conjectured to have seemingly manifested psychophysical faculty?
(Society for Scientific Exploration, 2022-12-30)
Whether and how consciousness could affect a physical system is a fundamental question. Radin et al (Radin et al 2012, 2013) reported that consciousness could perturb the fringe pattern of the classical experiment of ...
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 ...
On the geometry dependence of differential pathlength factor for near-infrared spectroscopy. I. Steady-state with homogeneous medium
(SPIE, the international society for optics and photonics, 2015-10-14)
This work analytically examines some dependences of the differential pathlength factor (DPF) for steady-state photon diffusion in a homogeneous medium on the shape, dimension, and absorption and reduced scattering coefficients ...
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 ...
On the stress-induced photon emission from organism: II, how will the stress-transfer kinetics affect the photo-genesis?
(Springer Nature, 2020-08-25)
Much remains to be identified for the temporal course of stress-induced photon emission (PE) following stress of various types including but not limited to light. Induced PE often decays hyperbolically; yet, it is not ...
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 ...
