Multimodal imaging monitoring of key physiological changes of peripheral arterial disease
… To define these landmarks, we use a multimodal imaging approach starting with Laser Speckle Contrast Imaging (LSCI) and Power Doppler ultrasound for perfusion (superficial and deep tissue, respectively); followed by fluorescent imaging of hypoxia and imaging both angiogenesis and metabolism …

Magnetically Actuated Microrobots for Tissue Elasticity Mapping in Colorectal Cancer Diagnosis
… methods such as colonoscopy and traditional imaging primarily rely on visual inspection, limiting their effectiveness in detecting early- stage lesions. Recent research highlights increased tumour stiffness due to cellular proliferation and extracellular matrix changes as a promising …

Optical Imaging Of Tissue Physiology With Exogenous Contrast Agents
… one can learn from optically emitting exogenous contrast agents in living tissue. The first set of experiments concurrently measured cerebral blood flow and bothintravascular- and extravascular-tissue oxygen concentration in a rat brain during functional activation; the new instrumentation needed …

Three dimensional simulation of functional neuro-vascular imaging
Functional optical imaging has become a powerful tool for measuring physiological parameters in the brain without disrupting normal physiology. Fluorescence lifetime imaging (FLIM) has been shown to allow near real time mapping of oxygen tension in plasma (pO2), and Laser Speckle Contrast Imaging …

Speckle applications for volumetric imaging of biological dynamics
Speckle is a high contrast granular pattern formed by coherent light interactions with rough surfaces or biological tissue. The speckle intensity fluctuates in space (or time) in a "random" manner and this randomness is often treated as noise in optical imaging. In another perspective, the speckle …
