Laser speckle imaging (LSI) techniques have emerged as a promising method for
visualizing functional blood vessels and tissue perfusion by analyzing the speckle patterns …

Background: Handheld laser speckle contrast imaging (LSCI) is crucial in clinical settings,
but motion artifacts (MA) can compromise perfusion image reliability. Current prevention and …

Background Skin microvasculature changes are crucial in psoriasis development and
correlate with perfusion. The noninvasive Handheld Perfusion Imager (HAPI) examines …

Significance In handheld laser speckle contrast imaging (LSCI), motion artifacts (MA) are
inevitable. Suppression of MA leads to a valid and objective assessment of tissue perfusion …

Significance The arterial input function (AIF) plays a crucial role in correcting the time-
dependent concentration of the contrast agent within the arterial system, accounting for …

Laser speckle contrast imaging (LSCI) is highly sensitive to motion artifacts. The blood flow
perfusion obtained by LSCI during tissue motion is a mixture with the artifacts due to inter …

Laser speckle contrast imaging or laser speckle imaging (LSI) is a noninvasive imaging
technology that can detect areas of dynamic perfusion or vascular flow. Thus, LSI has shown …

The existing statistical analysis-based laser speckle contrast imaging (LSCI) methods have
disadvantages in contrast, signal-to-noise ratio (SNR), and sensitive identification of small …

Speckle is a significant challenge for laser imaging systems, as it degrades the image
quality. In this study, an improved theoretical model is established to describe the speckle …

The evaluation of laser speckle statistics at different illumination angles is highly significant
in industry, eg, non-destructive surface inspection or motion analysis and measurement …
