Laser Speckle Imaging of Sensitized Acupoints. [PDF]
Evid Based Complement Alternat Med, 2018 Acupoints microcirculatory dynamics vary depending on the body's health status. However, the functional changes observed during acupoint sensitization, that is, the disease-induced change from a “silenced” to an “activated” status, remain elusive.

Combined laser speckle imaging and fluorescent intravital microscopy for monitoring acute vascular permeability reaction. [PDF]
J Biomed Opt, 2019 . Optical clearing agents (OCAs) and many chemicals are widely used in functional diagnosis of skin tissues. Numerous studies are associated with the transcutaneous diffusion of OCA in epidermal, dermal, and hypodermal tissues, which results in changing ...

Quantitative modeling of laser speckle imaging [PDF]
Optics Letters, 2006 We have analyzed the image formation and dynamic properties in laser speckle imaging (LSI) both experimentally and with Monte-Carlo simulation. We show for the case of a liquid inclusion that the spatial resolution and the signal itself are both ...

Simultaneous infrared thermal imaging and laser speckle imaging of brain temperature and cerebral blood flow in rats. [PDF]
J Biomed Opt, 2018 . Infrared thermal imaging of brain temperature changes is useful for evaluating cortical activity and disease states, such as stroke. However, the changes depend on a balance between changes in heat generation from metabolism and in heat convection ...

Rat retinal vasomotion assessed by laser speckle imaging. [PDF]
PLoS One, 2017 Vasomotion is spontaneous or induced rhythmic changes in vascular tone or vessel diameter that lead to rhythmic changes in flow. While the vascular research community debates the physiological and pathophysiological consequence of vasomotion, there is a ...
