System to Detect Often-Missed Cancer Tumors"},"content":{"rendered":"

Doctors may soon have help in the fight against cancer thanks to the UCF\u2019s Center for Research in Computer Vision.<\/p>\n

Engineers at the center have taught a computer how to detect tiny specks of lung cancer in CT scans, which radiologists often have a difficult time identifying. The artificial intelligence system<\/a> is about 95 percent accurate, compared to 65 percent when done by human eyes, the team says.<\/p>\n

\u201cWe used the brain as a model to create our system.\u201d \u2013 Rodney LaLonde, a doctoral candidate<\/p><\/blockquote>\n

\u201cWe used the brain as a model to create our system,\u201d says Rodney LaLonde, a doctoral candidate and captain of UCF\u2019s hockey team. \u201cYou know how connections between neurons in the brain strengthen during development and learn? We used that blueprint, if you will, to help our system understand how to look for patterns in the CT scans and teach itself how to find these tiny tumors.\u201d<\/p>\n

The approach is similar to the algorithms that facial-recognition software uses. It scans thousands of faces looking for a particular pattern to find its match.<\/p>\n

Engineering Assistant Professor Ulas Bagci leads the group of researchers in the center that focuses on AI with potential medical applications<\/a>.<\/p>\n

The group fed more than 1,000 CT scans \u2013 provided by the National Institutes of Health through a collaboration with the Mayo Clinic \u2013 into the software they developed to help the computer learn to look for the tumors.<\/p>\n

Graduate students working on the project had to teach the computer different things to help it learn properly. Naji Khosravan, who is pursuing his doctorate degree, created the backbone of the system of learning. His proficiency at novel machine learning and computer vision algorithms led to his summer as an intern at Netflix helping the company with various projects.<\/p>\n

\u201cLung cancer is the number one cancer killer in the United States and if detected in late stages, the survival rate is only 17 percent.” \u2013 Engineering Assistant Professor Ulas Bagci<\/p><\/blockquote>\n

LaLonde taught the computer how to ignore other tissue, nerves and other masses it encountered in the CT scans and analyze lung tissues. Sarfaraz Hussein who earned his doctorate degree this past summer, is fine-tuning the AI\u2019s ability to identify cancerous versus benign tumors, while graduate student Harish Ravi Parkash is taking lessons learned from this project and applying them see if another AI system can be developed to help identify or predict brain disorders.<\/p>\n

\u201cI believe this will have a very big impact,\u201d Bagci says. \u201cLung cancer is the number one cancer killer in the United States and if detected in late stages, the survival rate is only 17 percent. By finding ways to help identify earlier, I think we can help increase survival rates.\u201d<\/p>\n

The team will present its finding in September at the largest premier conference for medical imaging research \u2013 the MICCAI 2018 conference in Spain. The team\u2019s work has been published in advance of the conference.<\/p>\n
