Optical tomography in the presence of void regions.

Journal of the Optical Society of America. A, Optics, image science, and vision

Dehghani H, Arridge SR, Schweiger M, Delpy DT.
PMID: 10975376
J Opt Soc Am A Opt Image Sci Vis. 2000 Sep;17(9):1659-70. doi: 10.1364/josaa.17.001659.

There is a growing interest in the use of near-infrared spectroscopy for the noninvasive determination of the oxygenation level within biological tissue. Stemming from this application, there has been further research in the use of this technique for obtaining...

Enhanced time-resolved imaging with a diffusion model of photon transport.

Optics letters

Hebden JC, Delpy DT.
PMID: 19829626
Opt Lett. 1994 Mar 01;19(5):311-3. doi: 10.1364/ol.19.000311.

Imaging through highly scattering media with transmitted photons with the shortest flight times is limited ultimately by the available number of photons with sufficiently short paths. A method is described that enhances the performance of the time-resolved imaging technique....

Time-resolved optical imaging of a solid tissue-equivalent phantom.

Applied optics

Hebden JC, Hall DJ, Firbank M, Delpy DT.
PMID: 21068902
Appl Opt. 1995 Dec 01;34(34):8038-47. doi: 10.1364/AO.34.008038.

A solid plastic phantom has been developed with optical properties that closely match those of human breast tissue at near-IR wavelengths. The phantom is a 54-mm-thick slab containing four small cylinders of contrasting scatter and absorption. A detailed description...

Simultaneous reconstruction of absorption and scattering images by multichannel measurement of purely temporal data.

Optics letters

Hebden JC, Schmidt FE, Fry ME, Schweiger M, Hillman EM, Delpy DT, Arridge SR.
PMID: 18071563
Opt Lett. 1999 Apr 15;24(8):534-6. doi: 10.1364/ol.24.000534.

We present what is believed to be the first simultaneous reconstruction of the internal scattering and absorbing properties of a highly scattering medium by use of purely temporal data. These results are also the first acquired with the multichannel...

Data from 790 older school-age (Mage = 10.2 years, SD = 1.2 years) girls (N = 427) and boys from Barranquilla, Colombia (N = 449) and Montréal, Canada (N = 331) were used to replicate findings reported by Valdivia...

Three-dimensional time-resolved optical tomography of a conical breast phantom.

Applied optics

Hebden JC, Veenstra H, Dehghani H, Hillman EM, Schweiger M, Arridge SR, Delpy DT.
PMID: 11958270
Appl Opt. 2001 Jul 01;40(19):3278-87. doi: 10.1364/ao.40.003278.

A 32-channel time-resolved imaging device for medical optical tomography has been employed to evaluate a scheme for imaging the human female breast. The fully automated instrument and the reconstruction procedure have been tested on a conical phantom with tissue-equivalent...

Peer Influence on Academic Performance: A Social Network Analysis of Social-Emotional Intervention Effects.

Prevention science : the official journal of the Society for Prevention Research

DeLay D, Zhang L, Hanish LD, Miller CF, Fabes RA, Martin CL, Kochel KP, Updegraff KA.
PMID: 27436291
Prev Sci. 2016 Nov;17(8):903-913. doi: 10.1007/s11121-016-0678-8.

Longitudinal social network analysis (SNA) was used to examine how a social-emotional learning (SEL) intervention may be associated with peer socialization on academic performance. Fifth graders (N = 631; 48 % girls; 9 to 12 years) were recruited from...

Spectral dependence of temporal point spread functions in human tissues.

Applied optics

Essenpreis M, Elwell CE, Cope M, van der Zee P, Arridge SR, Delpy DT.
PMID: 20802707
Appl Opt. 1993 Feb 01;32(4):418-25. doi: 10.1364/AO.32.000418.

We have determined the spectral dependence of the temporal point spread functions of human tissues experimentally between 740 and 840 nm in transmittance measurements on the adult head, forearm, and calf (in vivo) and the infant head (post mortem)...
