Abstract: Abstract. Significance: High density diffuse optical tomography (HD-DOT) as applied in functional near-infrared spectroscopy (fNIRS) is largely limited to continuous wave (CW) data. Using a single modulation frequency, frequency domain (FD) HD-DOT has recently demonstrated… read more here.

DOI: 10.1117/1.nph.5.3.035006
Abstract: Abstract. Though optical imaging of human brain function is gaining momentum, widespread adoption is restricted in part by a tradeoff among cap wearability, field of view, and resolution. To increase coverage while maintaining functional magnetic… read more here.

DOI: 10.1364/boe.386567
Abstract: High density diffuse optical tomography has become increasingly important to detect underlying neuronal activities. Conventional methods first estimate the time courses of the changes in the absorption coefficients for all the voxels, and then estimate… read more here.

DOI: 10.1364/boe.467614
Abstract: Frequency domain (FD) high density diffuse optical tomography (HD-DOT) utilising varying or combined modulation frequencies (mFD) has shown to theoretically improve the imaging accuracy as compared to conventional continuous wave (CW) measurements. Using intensity and… read more here.

DOI: 10.1364/boe.469405
Abstract: A spatially weighted filter applied to both the measurement and the Jacobian is proposed for high-density diffuse correlation tomography (DCT) to remove unwanted extracerebral interferences and artefacts along with better depth localization in the reconstructed… read more here.

DOI: 10.1364/brain.2018.btu4c.3
Abstract: Using high density diffuse optical tomography neuroimaging data and a template-matching strategy, we were able to decode detailed information about the position of a checkerboard being viewed by a human subject. read more here.
