Real-time microcirculation imaging PeriCam PSI System YOUR PARTNER IN MICROCIRCULATION

INTRODUCTION The PeriCam PSI System is a blood perfusion imager based on Laser Speckle Contrast Analysis (LASCA) technology. LASCA provides new means to study the microcirculation in ways that were not possible in the past. It allows visualization of tissue blood perfusion in real-time and combines dynamic response with spatial resolution. There is no influence on the perfusion, as no direct contact to the tissue is needed, nor dyes or tracer elements. Examples ANIMALS Middle Cerebral Artery Occlusion Model – Stroke Examples Human Middle Cerebral Artery Occlusion (MCAO) is a commonly used...

What is Laser Speckle Contrast Analysis (LASCA)? When an object is illuminated by laser light, the backscattered light will form a random interference pattern consisting of light and dark areas. This pattern is called a speckle pattern. If the illuminated object is static, the speckle pattern is stationary. When there is movement in the object, such as red blood cells in a tissue, the speckle pattern will change over time. Depending on the degree of movement, the level of blurring will differ. The more movement, the more blurred the speckle pattern will appear. The level of blurring is...
