UT Health San Antonio pathologists and Southwest Research Institute engineers placed first in an international challenge to develop an automated method to detect breast cancer tumor cells.
They trained a computer algorithm previously used for automotive, robotics and defense applications to identify cancer cells for the BreastPathQ: Cancer Cellularity Challenge. The American Association of Physicists in Medicine, the National Cancer Institute and SPIE, the international society for optics and photonics conducted the competition..
“Adapting an autonomous robotics algorithm to solve a health diagnostics problem shows that we really have state-of-the-art techniques,” said Hakima Ibaroudene, SwRI engineer and challenge leader. “Our method has the potential to improve medical imaging, ultimately bolstering health care for cancer patients.”
The process of developing the cancer-detecting algorithm began with UT Health San Antonio pathologists teaching the SwRI engineers to recognize breast cancer tumor cells. The engineers then trained the computer algorithm to analyze cell images, looking for defining characteristics that distinguish the cancerous cells from normal ones. Once trained, the SwRI algorithm sorted through images provided for the challenge and matched the findings of human pathologists at the highest rate, making it the top-performing algorithm out of 100 competing submissions.
“Artificial intelligence and machine learning approaches to medical image analysis will provide pathologists with a powerful tool to more rapidly identify and quantify important image features,” said Bradley Brimhall, M.D., M.P.H., UT Health San Antonio pathologist and challenge participant. “In doing so, additional diagnostic and prognostic information will be available for providers to guide cancer treatment.”
The challenge team also includes Donald Poole, SwRI engineer, and Edward Medina, M.D., Ph.D., UT Health San Antonio pathologist. Team members will present their winning algorithm at the 2019 SPIE Medical Imaging Conference on Feb. 20 in San Diego.
