Overview

The LSCI technology advantages are its non-contact,  no contrast agent required, high frame-rate,  high spatial resolution.  They can be used to observe and record blood perfusion of any exposed tissues or organs for microcirculation study or pre-clinical researches like ischemic stroke,  lower limbs, mesentery,  etc.  Multi-Output includes blood perfusion images and videos (500+ million pixels),  quantified data for perfusion unit and vessel diameter.

Since 2019,  our imaging system has been adopted by more than 200 colleges,  universities,  and research institutes worldwide such as Stanford University School of Medicine,  Yale University, University of Manchester, Duke university, University College London, University of Tasmania, Universitaet Gesamthochschule Essen, Korea University. What’s more,  it has contributed to publishing more than 200 reputed research papers in magazines like Nature Neuroscience、Gut、Brain、Blood、Circulation Research、Nano Today、Nature Communications、 Advanced Functional Materials and Diabetes.

Applications:

  • Cerebral blood perfusion monitoring

  • MCAO model assessment

  • Cortical spreading depression observation

  • Hind-limb ischemia research

Clients Say

Clinical & Experimental Epilepsy

“I couldn’t suggest further hardware features as I feel everything the user would need is there. The quality of the images is wonderful, The pixel resolution of the images is very impressive also. The user friendly software allows the user to control all aspects of both the operation of the machine but also the analysis of the results. The features available for data analysis, such as the ROI function and blood perfusion graph, allow for exciting results. .....”
