“…The optical bandwidth of the MDBBS is 564nm (504-1068nm) and the mean wavelength resolution is 4nm. The MDBBS is an upgrade of an early design of a Lens Imaging Spectrograph (or LImS) developed earlier [ 2 ].…”

For resolving absolute concentration of tissue chromophores in the human adult brain with near-infrared spectroscopy it is necessary to calculate the light scattering and absorption, at multiple wavelengths with some depth resolution. To achieve this we propose an instrumentation configuration that combines multi-distance frequency and broadband spectrometers to quantify chromophores in turbid media by using a hybrid spatially resolved algorithm. Preliminary results in solid phantoms as well as liquid dynamic homogeneous and inhomogeneous phantoms and in-vivo muscle measurements showed encouraging results.

“…In addition the geometry of the fibre bundles on the distal end was changed from round to approximate oval in order to decrease the area blocked by the slit. The MDBBS is an upgrade of an early design of a Lens Imaging Spectrograph (or LImS) [4]. The phantom contained 2850ml of deionised water mixed with 150ml of an aqueous scattering suspension (Intralipid-20%); to that mix an absorbing compound, a green dye (Indocyanine green or ICG) was added in four steps of 0.5ml from 25mg of ICG diluted at 200ml of deionised water.…”

For resolving absolute concentration of tissue chromophores in the human adult brain with near-infrared spectroscopy it is necessary to calculate the light scattering and absorption, at multiple wavelengths with some depth resolution. We report a novel methodology that combines multi-distance frequency and broadband spectrometers to quantify chromophores in turbid media by using a spatially resolved algorithm. Preliminary results in a dynamic phantom showed good agreement between measured and theoretical calculated absolute concentrations of known dyes.
