متن کاملRetinotopic mapping of adult human visual cortex with high-density diffuse optical tomography.
Functional neuroimaging is a vital element of neuroscience and cognitive research and, increasingly, is an important clinical tool. Diffuse optical imaging is an emerging, noninvasive technique with unique portability and hemodynamic contrast capabilities for mapping brain function in young subjects and subjects in enriched or clinical environments. We have developed a high-performance, high-de...
متن کاملHigh-density diffuse optical tomography of term infant visual cortex in the nursery.
Advancements in antenatal and neonatal medicine over the last few decades have led to significant improvement in the survival rates of sick newborn infants. However, this improvement in survival has not been matched by a reduction in neurodevelopmental morbidities with increasing recognition of the diverse cognitive and behavioral challenges that preterm infants face in childhood. Conventional ...
متن کاملRecycling Subspace Information for Diffuse Optical Tomography
We discuss the efficient solution of a long sequence of slowly varying linear systems arising in computations for diffuse optical tomographic imaging. The reconstruction of three-dimensional absorption and scattering information by matching computed solutions from a parameterized model to measured data leads to a nonlinear least squares problem that we solve using the Gauss–Newton method with a...
متن کاملInformation theoretic regularization in diffuse optical tomography.
Diffuse optical tomography (DOT) retrieves the spatially distributed optical characteristics of a medium from external measurements. Recovering the parameters of interest involves solving a nonlinear and highly ill-posed inverse problem. This paper examines the possibility of regularizing DOT via the introduction of a priori information from alternative high-resolution anatomical modalities, us...
