Artificial intelligence, or the use of machine learning algorithms and deep learning programs to mimic human cognition or rationality, has become the backbone of many of our daily activities. Now, artificial intelligence (AI) is increasingly being applied to health care data analysis, particularly in the fields of precision medicine, diagnosis, and patient monitoring. These technologies have the potential to revolutionize patient care and disrupt the operations of healthcare organizations. But what can we expect when these technologies are applied in the fields of healthcare and medicine, which are rooted in the human touch?

In this discussion, Dr. Austin Chiang, chief medical officer of Medtronic Gastroenterology, the first company to launch an artificial intelligence program for colonoscopy, and Columbia University professor Andrew Lin, who studies mathematical analysis for computer-aided diagnosis, explore the state of the field. , ethical considerations/pitfalls, and impact on patient care.

Time will be allocated for questions and answers.

Andrew F Lin He is the director of the Hefner Biomedical Imaging Laboratory in Columbia, where he focuses on mathematical analysis and quantification of medical images, signal and image processing, computer-aided diagnosis, and biomedical/imaging informatics. His work is based on the analysis of pictorial structures at the molecular, cellular, tissue and organ levels. The goal is to develop biomedical technology to meet unmet clinical needs and turn this technology into commercial products that improve healthcare and save lives.

Lin was the first to use multiband wavelet representation to enhance fine detail in mammograms. Today, the algorithm he developed in 1992 is used in almost all commercial digital mammography systems. Currently, Lane applies multi-solution wavelet techniques to classify pulmonary emphysema. He is also collaborating on a project in the field of medical informatics to enable clinicians to better diagnose a patient using text and annotated results from medical images. Laine’s work is based on techniques such as time-frequency decomposition/representation, blot tracking, texture analysis, machine and deep learning, variable segmentation, parametric distortion models, and image reconstruction.

Lin received a Bachelor’s degree in Biological Sciences from Cornell University in 1977, a Master’s degree in Chemistry from the University of Connecticut in 1980, and a Ph.D. in Computer Science from Washington University, St. Louis, in 1989. He is a Fellow of the Institute of Electrical and Electronics Engineers and the International Federation of Medical and Biological Engineering. He is also a member of the Data Science Institute of Columbia.

Austin Xiang Triple board certified, he is a specialist in gastroenterology and advanced endoscopy. In October 2021, he became the first medical officer for the gastro-intestinal business of Medtronic, the world’s leading manufacturer of medical devices responsible for products including Barrx radiofrequency ablation devices and Pillcam capsule endoscopic products, EndoFLIP, Bravo, Sharkcore and GI Genius first-to-market AI-assisted polyp detection device to help endoscopy specialists better prevent colon cancer. Dr. Chiang’s interests include new endoscopic weight loss therapies as well as complex endoscopic procedures including diagnosis and treatment of various gastrointestinal diseases and their complications. It includes a variety of cancers that affect the digestive system such as pancreas, bile duct, esophagus, stomach, colon and liver cancer.

Dr. Chiang is currently an Assistant Professor of Medicine at Jefferson Health (Thomas Jefferson University Hospitals) in Philadelphia, Pennsylvania, and serves as the Director of the Endoscopic Weight Loss Program and Director of Medical Social Media for the Health System. It is fully licensed and approved in Pennsylvania and Massachusetts. Having trained in the only dedicated bariatric endoscopy program, he became one of the few doctors with triple certifications in the field of advanced endoscopy in the world. His triple board certifications include Internal Medicine and Gastroenterology from the American Board of Internal Medicine, and in Obesity Medicine from the American Board of Obesity Medicine.
