Dynamic light scattering imaging

DD Postnov, J Tang, SE Erdener, K Kılıç, DA Boas - Science advances, 2020 - science.org
We introduce dynamic light scattering imaging (DLSI) to enable the wide-field measurement
of the speckle temporal intensity autocorrelation function. DLSI uses the full temporal …

The nephron-arterial network and its interactions

DJ Marsh, DD Postnov… - American Journal …, 2019 - journals.physiology.org
Tubuloglomerular feedback and the myogenic mechanism form an ensemble in renal
afferent arterioles that regulate single-nephron blood flow and glomerular filtration. Each …

Choosing a model for laser speckle contrast imaging

…, SE Erdener, DA Boas, DD Postnov - Biomedical Optics …, 2021 - opg.optica.org
Laser speckle contrast imaging (LSCI) is a real-time full-field non-invasive technique, which
is broadly applied to visualize blood flow in biomedical applications. In its foundation is the …

[HTML][HTML] Choosing a laser for laser speckle contrast imaging

DD Postnov, X Cheng, SE Erdener, DA Boas - Scientific reports, 2019 - nature.com
The use of laser speckle contrast imaging (LSCI) has expanded rapidly for characterizing the
motion of scattering particles. Speckle contrast is related to the dynamics of the scattering …

[HTML][HTML] Chronic cranial windows for long term multimodal neurovascular imaging in mice

…, S Sunil, ŞE Erdener, DD Postnov… - Frontiers in …, 2021 - frontiersin.org
Chronic cranial windows allow for longitudinal brain imaging experiments in awake,
behaving mice. Different imaging technologies have their unique advantages and combining …

Estimation of vessel diameter and blood flow dynamics from laser speckle images

DD Postnov, VV Tuchin, O Sosnovtseva - Biomedical optics express, 2016 - opg.optica.org
Laser speckle imaging is a rapidly developing method to study changes of blood velocity in
the vascular networks. However, to assess blood flow and vascular responses it is crucial to …

Multi-scale laser speckle contrast imaging of microcirculatory vasoreactivity

…, CM Sørensen, DD Postnov - Biomedical Optics …, 2022 - opg.optica.org
… High-zoom BFI map averaged over time was used to segment individual blood vessels on
the renal surface as described by Postnov [20]. Briefly, an adaptive intensity threshold was …

[HTML][HTML] Adaptation to shift work: Physiologically based modeling of the effects of lighting and shifts' start time

S Postnova, PA Robinson, DD Postnov - PloS one, 2013 - journals.plos.org
Shift work has become an integral part of our life with almost 20% of the population being
involved in different shift schedules in developed countries. However, the atypical work times, …

[HTML][HTML] Optimizing the precision of laser speckle contrast imaging

…, S Zilpelwar, S Sunil, DA Boas, DD Postnov - Scientific Reports, 2023 - nature.com
Laser speckle contrast imaging (LSCI) is a rapidly developing technology broadly applied
for the full-field characterization of tissue perfusion. Over the recent years, significant …

Does Src kinase mediated vasoconstriction impair penumbral reperfusion?

HO Guldbrandsen, C Staehr, NK Iversen, DD Postnov… - Stroke, 2021 - Am Heart Assoc
Despite successful recanalization, a significant number of patients with ischemic stroke
experience impaired local brain tissue reperfusion with adverse clinical outcome. The cause and …
