Laser Speckle Rheology

Laser speckle rheology is a technique of beaming a laser through an organic material, revealing a light scattering pattern (speckle) that presents the mechanical properties of its flow (rheology). If the organic material is a blood sample, LSR can detect the concentration of fibrinogen and deduce clotting time.  With this in mind, engineers at Massachusetts General Hospital have created a Kleenex box-size LSR device that could give emergency room doctors life-saving transfusion information for a hemorrhaging patient in a matter of minutes.   MORE
