Kirkpatrick S, Wang R, Duncan D
Opt Express
. 2009 Jun;
14(24):11585-97.
PMID: 19529578
We present two approaches to speckle tracking for optical coherence tomography (OCT)-based elastography, one appropriate for small speckle motions and the other for large, rapid speckle motions. Both approaches have...

Kirkpatrick S, Wang R, Duncan D, Kulesz-Martin M, Lee K
Opt Express
. 2009 Jun;
14(21):9770-9.
PMID: 19529368
Optical elastography is an imaging modality that relies on variations in the local mechanical properties of biological tissues as the contrast mechanism for image formation. Skin lesions, such as melanomas...

Kirkpatrick S, Duncan D, Wells-Gray E
Opt Lett
. 2008 Dec;
33(24):2886-8.
PMID: 19079481
Through a series of simulations and experiments, we demonstrate that the frequently cited criterion of matching speckle size to detector element (pixel) size in laser speckle contrast imaging (LSCI) has...

J Biomed Mater Res A
. 2008 Nov;
91(2):528-39.
PMID: 18985765
Endothelial cells (ECs) produce and maintain the local extracellular matrix (ECM), a critical function that contributes to EC and blood vessel health. This function is also crucial to vascular tissue...

J Opt Soc Am A Opt Image Sci Vis
. 2008 Aug;
25(8):2088-94.
PMID: 18677371
The ultimate objective of laser speckle flowmetry (and a host of specific implementations such as laser speckle contrast analysis, LASCA or LSCA; laser speckle spatial contrast analysis, LSSCA; laser speckle...

Endothelial cell cytoskeletal alignment independent of fluid shear stress on micropatterned surfaces
Vartanian K, Kirkpatrick S, Hanson S, Hinds M
Biochem Biophys Res Commun
. 2008 May;
371(4):787-92.
PMID: 18471992
Endothelial cells (ECs) in athero-protective regions are elongated with actin and microtubule fibers aligned parallel to the direction of blood flow. Fluid shear stress (FSS) affects EC shape and functions,...

Duncan D, Kirkpatrick S
J Opt Soc Am A Opt Image Sci Vis
. 2007 Dec;
25(1):231-7.
PMID: 18157231
Use of a copula for generating a sequence of correlated speckle patterns is introduced. The chief characteristic of this algorithm is that it generates a continuous speckle sequence with a...

J Opt Soc Am A Opt Image Sci Vis
. 2007 Dec;
25(1):9-15.
PMID: 18157206
In describing the first-order properties of laser speckle under polarized illumination conditions, it is almost an article of faith that the contrast is unity. In many processing schemes, however, the...

J Opt Soc Am A Opt Image Sci Vis
. 2007 Dec;
24(12):3728-34.
PMID: 18059925
We demonstrate through a series of simulations that by parameterizing the temporal speckle contrast statistic from a sequence of translating speckle images on a number of experimental constants, the local...

PMID: 16453334
Elastin, a principal structural component of native arteries, has distinct biological and mechanical advantages when used as a biomaterial; however, its low ultimate tensile strength has limited its use as...
