Daniel Rosen using our microscope for pathology education

Microscopes are a key tool in pathology, used for diagnosing dozens of conditions including cancer and infections. Many areas of the Global South have limited access to lab-grade slide scanners, making diagnosis and training more challenging.

As a low-cost automated microscope, the OpenFlexure Microscope can be used in low-resource settings, allowing clinicians to automate the scanning of their samples. The resulting digital images can be used for training, diagnosis or telepathology — getting a second opinion from a remote specialist, without shipping the sample or delaying diagnosis.

Dr Daniel Rosen, Professor of Pathology at the Baylor College of Medicine, has been instrumental in demonstrating this use. As a global health specialist, he has used the OpenFlexure Microscope in Brazil and Rwanda, imaging patient samples to enable the training of medical students on digital images. We’re working towards certification of our design, giving clinicians more confidence.

In January 2024, Daniel was joined by Joe and Dr Kelsey Hummels (MD Anderson Cancer Centre) to install four OpenFlexure Microscopes in the CHUB Hospital in Butare, southern Rwanda. The automated scanning of patient samples was assessed, with publications in progress.

Or to read the publications that have come from this work so far, Daniel has published about using the OFM for esophageal biopsies in Brazil. Cabello et al. have evaluated our microscope for diagnosing Tuberculosis and Rheumatic Heart Disease in Philippine health centres.
