Characterization of light transport in scattering media at sub-diffusion length scales with Low-coherence Enhanced Backscattering.

IEEE journal of selected topics in quantum electronics : a publication of the IEEE Lasers and Electro-optics Society

Turzhitsky V, Rogers JD, Mutyal NN, Roy HK, Backman V.
PMID: 21037980
IEEE J Sel Top Quantum Electron. 2010;16(3):619-626. doi: 10.1109/JSTQE.2009.2032666.

Low-coherence enhanced backscattering (LEBS) is a technique that has recently shown promise for tissue characterization and the detection of early pre-cancer. Although several Monte Carlo models of LEBS have been described, these models have not been accurate enough to...

Comparison of various wavelet texture features to predict beef palatability.

Meat science

Jackman P, Sun DW, Allen P.
PMID: 20416619
Meat Sci. 2009 Sep;83(1):82-7. doi: 10.1016/j.meatsci.2009.04.003. Epub 2009 Apr 09.

The wavelet transform can be used to characterise the surface texture of beef images in a more efficient manner than classical algorithms such as co-occurrence and run lengths. Features extracted from wavelet decompositions have been used to develop predictive...

Optical analysis of nanoparticles via enhanced backscattering facilitated by 3-D photonic nanojets.

Li X, Chen Z, Taflove A, Backman V.
PMID: 19488381
Opt Express. 2005 Jan 24;13(2):526-33. doi: 10.1364/opex.13.000526.

We report the phenomenon of ultra-enhanced backscattering of visible light by nanoparticles facilitated by the 3-D photonic nanojet - a sub-diffraction light beam appearing at the shadow side of a plane-waveilluminated dielectric microsphere. Our rigorous numerical simulations show that...

Fungal Parasites of the Potato Cyst Nematode Globodera rostochiensis: Isolation and Reinfection.

Journal of nematology

Dackman C.
PMID: 19287764
J Nematol. 1990 Oct;22(4):594-7.

Fungal parasitism of eggs of the potato cyst nematode Globodera rostochiensis was < 1, 3, and 17% at three sites in Sweden. The fungi isolated most frequently from infected eggs were a Septocylindrium-like fungus ( 19 %), Exophiala spp....

Computerized tomography: a method to study cross-sectional muscle area in nutritional evaluation.

Clinical nutrition (Edinburgh, Scotland)

Backman L, Nordenvall B, Tydén A.
PMID: 16829446
Clin Nutr. 1984 Jul;3(2):121-4. doi: 10.1016/s0261-5614(84)80011-4.

We have compared two ways of determining cross-sectional muscle area in patients undergoing total parenteral nutrition, namely, computerised tomography and anthropometric measurements. There was a poor correlation between the two methods of determining cross-sectional limb area. The cross-sectional area...

Depth-resolved measurement of mucosal microvascular blood content using 
low-coherence enhanced backscattering spectroscopy.

Radosevich AJ, Turzhitsky VM, Mutyal NN, Rogers JD, Stoyneva V, Tiwari AK, De La Cruz M, Kunte DP, Wali RK, Roy HK, Backman V.
PMID: 21258541
Biomed Opt Express. 2010 Oct 20;1(4):1196-1208. doi: 10.1364/BOE.1.001196.

Low-coherence enhanced backscattering (LEBS) spectroscopy is a light scattering technique which uses partial spatial coherence broadband illumination to interrogate the optical properties at sub-diffusion length scales. In this work, we present a post-processing technique which isolates the hemoglobin concentration...

Evidence-based Guidelines for Precision Risk Stratification-Based Screening (PRSBS) for Colorectal Cancer: Lessons learned from the US Armed Forces: Consensus and Future Directions.

Journal of Cancer

Avital I, Langan RC, Summers TA, Steele SR, Waldman SA, Backman V, Yee J, Nissan A, Young P, Womeldorph C, Mancusco P, Mueller R, Noto K, Grundfest W, Bilchik AJ, Protic M, Daumer M, Eberhardt J, Man YG, Brücher BL, Stojadinovic A.

J Cancer. 2013;4(3):172-92. doi: 10.7150/jca.5834. Epub 2013 Mar 01.

Colorectal cancer (CRC) is the third most common cause of cancer-related death in the United States (U.S.), with estimates of 143,460 new cases and 51,690 deaths for the year 2012. Numerous organizations have published guidelines for CRC screening; however,...

Polarized Enhanced Backscattering Spectroscopy for Characterization of Biological Tissues at Subdiffusion Length-scales.

IEEE journal of selected topics in quantum electronics : a publication of the IEEE Lasers and Electro-optics Society

Radosevich AJ, Rogers JD, Turzhitsky V, Mutyal NN, Yi J, Roy HK, Backman V.
PMID: 24163574
IEEE J Sel Top Quantum Electron. 2012 Jul;18(4):1313-1325. doi: 10.1109/JSTQE.2011.2173659.

Since the early 1980's, the enhanced backscattering (EBS) phenomenon has been well-studied in a large variety of non-biological materials. Yet, until recently the use of conventional EBS for the characterization of biological tissue has been fairly limited. In this...

Sixty thousand woman-years of experience on the levonorgestrel intrauterine system: an epidemiological survey in Finland.
