A method and system for determination and mapping the quantity of chromophores having a distinct spectrum attached to moving objects in an spectrally rich environment that may include multiple chromophores attached to stationary objects. Au area of interest is imaged at different times and different wavelengths, and the spectral properties of the chromophores attached to the moving objects are separated from the stationary spectral properties of the background, followed by spectral analysis of the moving objects to determine their quantity. Application to the retinal vasculature is illustrated, showing the imaging, analyzing and quantifying of the oxygen saturation of retinal blood, resolved for the different vascular compartments, including capillaries, arterioles, venules, arteries, and veins.

The invention discloses an endogenous optical imaging method for automatically separating arteries and veins and aims at providing an effective endogenous optical imaging method for effectively and automatically separating arteries and veins of organisms. In the technical scheme, the endogenous optical imaging method comprises the following steps of: carrying out spectrum analysis to a collected image sequence by adopting narrow-band quasi monochromatic light for illumination, and then realizing the identification and automatic separation of the arteries and veins by utilizing the amplitude distribution features of low-frequency oscillating signals of the image sequence through the operations of frequency spectrum transformation, enhancement of a local self-adaption contrast, automatic threshold segmentation and the like. The endogenous optical imaging method can be used for automatically separating the arteries and the veins and highlighting and separating the vessel structures of many arterioles and veinlets, thereby avoiding the design complexity of the imaging device using light with various central wavelengths for illumination.

Automated quantitative analysis of microcirculation, such as density of blood vessels and red blood cell velocity, is implemented using image processing and machine learning techniques. Detection and quantification of the microvasculature is determined from images obtained through intravital microscopy. The results of quantitatively monitoring and assessing the changes that occur in microcirculation during resuscitation period assist physicians in making diagnostically and therapeutically important decisions such as determination of the degree of illness as well as the effectiveness of the resuscitation process. Advanced digital image processing methods are applied to provide quantitative assessment of video signals for detection and characterization of the microvasculature (capillaries, venules, and arterioles). The microvasculature is segmented, the presence and velocity of Red Blood Cells (RBCs) is estimated, and the distribution of blood flow in capillaries is identified for a variety of normal and abnormal cases.

The present invention relates to a therapy system for the treatment of the skin and subdermis with light. The system comprises a NIR light source which produces light with a wavelength adapted to an absorption maximum for exciting molecular oxygen in aqueous solution; an image recognition unit for detecting papillary end arterioles and their x-y-z coordinates, wherein a respective depth underneath the skin surface is determined as the z-coordinate by an autofocus function; an optical system for the optical coupling of the light of the NIR light source and the pattern recognition unit to the skin, with a focussing unit to controllably position the light with at least one focus point in the skin; and a control unit to control the NIR light source, the image recognition unit, and the optical system.

The present invention belongs to the technical field of traditional Chinese medicine, in particular to a traditional Chinese medicine composition for adjuvantly treating the hemorrhagic stroke. The traditional Chinese medicine composition is prepared from the following raw medicine materials in parts by weight: 3-10 parts of pseudo-ginseng, 3-10 parts of cattail pollen, 3-10 parts of rhizoma bletillae, 3-6 parts ofcarbonized hair, 2-5 parts of scorpion, 3-10 parts of rhizoma gastrodiae, 10-15 parts of uncaria rhynchophylla, 15-20 parts of sea-ear shell, 10-15 parts of chrysanthemum, 1-3 parts of antelope horn,1.5-6 parts of arisaema cum bile and 10-15 parts of plantain seed. The composition has the double regulating effects of stopping bleeding and dissolving stasis, not only can stop bleeding without stasis, but also can dissolve the stasis without bleeding, thereby effectively making up for the defect that western medicine is easy to cause thrombus during stopping bleeding. The composition is used for the auxiliary treatment of the hemorrhagic stroke caused by cerebral arteriole bleeding because of high blood pressure, cerebral arteriosclerosis, cerebral arteritis, cerebral bottom aneurysm or cerebral artery and vein deformity, and the like and has unexpected good effect.

The invention discloses an application of analgesic anti-inflammatory ointment in preparing medicine for treating carotid artery arteriosclerosis cerebral infarction. The analgesic anti-inflammatory ointment is externally paved on the carotid artery area taking carotid bifuracation as centre so as to promote endothelium growth of blood vessel effectively, accelerate recovery and healing of endangium, stabilize or shorten atheromatous plaque, accelerate recovery, relieve symptom and reduce recurring risk; and the invention is convenient to operate, is economic and suitable and has no toxic or side effects.
