Researchers at the University of Tokyo have developed an AI-powered microscope that can observe blood clot formation in real time.

By capturing thousands of images per second, the tool analyses how platelets behave and clump together, offering a non-invasive way to assess clot risk in patients with coronary artery disease.

Unlike current methods that rely on indirect markers or invasive procedures, the AI tool provides live visual data using a simple blood draw from the arm. The results closely matched samples taken directly from the arteries, making the approach both safer and more accessible.

Japanese doctors could soon use this technology to evaluate how well blood-thinning drugs are working on an individual basis. While still in the research phase, experts believe it may eventually transform point-of-care decision-making for heart patients.
