Doctors are reporting a proliferation of dangerous blood clots in the lungs and other major organs of COVID-19 patients, raising the risk of stroke and other life-threatening complications. While anticoagulant medications can reduce that risk, patients need careful monitoring to ensure their blood is neither too thick nor too thin. To that end, Los Angeles-based startup Neural Analytics Inc. is deploying its robotically assisted transcranial doppler (TCD) system for real-time identification of blood clots and disruptions in blood flow to the brain.
