Vascular Imaging

Vascular imaging is a test that enables to access and evaluate the body’s circulatory system and help identify blockages in veins and arteries and detect blood clots. Non-optical methods that are widely used for vascular images includes X-ray/CT, MRI, ultrasound and positron emission tomography. These techniques are most popularly used for macrovascular imaging but due to poor spatial contrast these are not effective for microvascular imaging. Optical methods recommended for microvascular imaging are single-photon fluorescence microscopy (1PFM), two-photon fluorescence microscopy, orthogonal polarization spectral imaging (OCSI), laser speckle contrast imaging (LSCI), diffusive imaging, diffuse optical tomography etc.,
