Researchers at Lehigh University have developed a computer-aided diagnostic technique that combines imaging technology with the latest advances in artificial intelligence to detect in real time the difference between cancerous and benign cells.
“The idea is that one day, if this technique could be used during surgery, it could complement the histopathology, potentially reducing the need for a second breast cancer surgery,” says Lehigh professor Chao Zhou.
He notes a feasibility study found the new technique achieved a classification accuracy of more than 90%.
Zhou says the method uses a new application of an imaging technique called optical coherence microscopy (OCM) as a breast cancer diagnostic. Features extracted from the OCM images are used to train the computer system to automatically identify different tissue types.
After examining multiple types of texture features, the researchers found Local Binary Pattern features worked best for classifying tissues imaged via OCM.
