Hemorai enables clinicians to extend acute care to the patient’s home via reliable continuous monitoring of clinical parameters including many that traditionally required a laboratory evaluation. We provide solutions that overall reduce the healthcare spend, while expanding access to care.
Patient recovery often necessitates costly overnight stays for monitoring, particularly for hemorrhage risks. This occupies hospital beds and resources, reducing the availability of expensive services.
Hemorai is improving on a technology developed by UCI with the name of Coherent Spatial Imaging (CSI) system that combines the optical property measurements of srDRS with SPG- based blood flow measurements. This CSI technique allows high-speed measurements of speckle contrast and diffuse reflectance.
Tim Phillips, Ph.D. is a mechanical engineer with a passion for design and manufacturing. At Hemorai and as a consultant, he has driven the design process for numerous biomedical devices, including optical imaging systems, tissue harvesting probes, and medical storage monitoring devices. Tim has experience taking these ideas from rough sketches through ideation and prototyping and into early-stage production.
As a researcher, Tim has focused on improving control for manufacturing systems and developing new functional materials for Additive Manufacturing. Dr. Phillips has worked on developing flaw detection methods in Additive Manufacturing systems and designed novel control architectures to improve manufacturing outcomes. He has also created and evaluated unique materials for Additive Manufacturing, such as lithium-ion battery materials, high-temperature ceramics, and high-strength implantable polymers.
Nitesh Katta, Ph.D. worked in the field of applied electrical engineering for more than 12 years. Nitesh has worked in the field of biomedical optics and fundamental laser-surgery research for more than 6 years. As part of his doctoral dissertation, he developed bench-top and catheter systems for image-guided surgery for brain cancer tumor resection in in vivo xenograft murine models. Nitesh is one of the early developers of precision in vivolaser surgery for brain cancer utilizing optical coherence tomography (OCT).
Austin McElroy, M.Sc. has been a research scientist for over 15 years in almost all aspects of Electrical Engineering: circuit design, embedded systems, high speed parallel computing, and machine learning. Mr. McElroy’s master’s work mainly focused on biomedical optics and imaging, Austin has expanded his expertise to other bio-signals such as EEG and EKG data acquisition and wireless transmission. As a lead software architect in two labs, Mr. McElroy often managed and coordinated graduate students’ efforts ensuring projects were completed on time within the scope of the budget. Many of these projects were funded by the NIH and NSF, so he has an appreciation for cost sensitivity and addressing problems as they arise within the scope of the proposed budget.
Hemorai is improving on a technology developed by UCI with the name of coherent spatial imaging (CSI) system that combines the optical property measurements of srDRS with SPG- based blood flow measurements. This CSI technique allows high-speed measurements of speckle contrast and diffuse reflectance, which provide critical information to assess absolute measurements of pulsatile blood flow, blood volume, stO2, and tMRO2. Using miniaturized optoelectronic components allows us to map radially-varying diffuse reflectance of coherent light from tissues, which in turn enables absolute measurement of absorption and scattering contrast. As the supply and utilization of oxygen can become decoupled in abnormal physiological states, CSI has the potential to measure the hemodynamic dysfunction that is expected to occur during early stages of hemorrhage.
