Abstract

DESCRIPTION provided by applicant There is a strong unmet need for a low cost and convenient technology that can assist researchers and healthcare personnel in gathering vascular data Such vascular imaging technology could assist in the short term clinica research on the diagnostics disease progression and effect of treatment prevention strategies In the long term the same technology could integrate into the healthcare system
for diagnosis monitoring and management of disease in primary care environments especially relevant for the aging population that may have restricted mobility Diseases that are thought to show vascular symptoms or manifestations in the retina include diabetic hypertensive retinopathies stroke cardiovascular disease and Alzheimerandapos s disease Skin vasculature could be monitored for identification of melanomas classification of wounds burns assessment of healing and titration of therapy through evaluation of skin vasculature Our team has developed an optical imaging platform based on laser speckle contrast imaging LSCI technology that can for the first time probe individual microvesses for their diameters local density and blood flow over a large field of view without the need for any contrast agents Vasoptic Medical Inc is seeking to develop further and commercialize this technology originally created at Johns Hopkins University in an effrt to make vascular imaging low cost and available to clinicians healthcare workers and researchers at large Specifically in this Phase I we will develop and make available to researchers a a powerful LSCI based software suite that can image blood vessel diameters density and flow and enable comparison in longitudinal experiments b a low cost and portable implementation of the LSCI platform ezLSCI by designing a novel complementary metal oxide semiconductor CMOS imager chip that will match the sensitivity noise and resolution characteristics of current CCD cameras while offering considerable improvements in power consumption size speed and system integration An FPGA based system operational module will control the device operation including illumination image processing and image storage transmission The performance of the ezLSCI system and software will be characterized in preclinical models of retinal imaging and skin imagin The ability of the ezLSCI system to discriminate healthy retinal blood flow from decreased retinal blood flow common in disease conditions will be demonstrated through the systemic administration of a vasoconstrictive agent Further the ability of the
ezLSCI system to monitor the effects of therapeutic interventions will be demonstrated in a skin wound healing model with topical administration of an anti angiogenic agent Upon successful completion of Phase I milestones our Phase II effort will comprise a more
rigorous validation of the ezLSCI for skin imaging in a porcine model and a proof of concept clinical study with due regulatory approvals We will seek private investment to support a clinical study that investigates the use of ezLSCI for early detection of retinopathy PUBLIC HEALTH RELEVANCE This project if successful will enable a novel low cost optical imaging instrument that can be used for vascular imaging at primary care for both clinical research and clinical practice Taking a diagnostic test or a research tool to a patient or at ris individual is critical to manage and also research health conditions in which the patint has restricted mobility due to age disease or injury Imaging the retinal vasculatur has potential to detect diabetic hypertensive retinopathies and stroke while imaging the ski vasculature has the potential to detect melanomas and assess wounds and burns
