Yoshinobu Sato received his B.S., M.S. and Ph.D. degrees in Information and Computer Sciences from Osaka University, Japan in 1982, 1984, and 1988, respectively. From 1988 to 1992, he worked at the NTT Human Interface Laboratories. In 1992, he joined Osaka University Medical School. From 1996 to 1997, he was a Visiting Research Fellow at the Surgical Planning Laboratory, Harvard Medical School and Brigham and Women's Hospital. In 1999, he became an Associate Professor at Osaka University Graduate School of Medicine. From 2014 to 2025, he was a Professor at the Nara Institute of Science and Technology (NAIST). Currently, he is a Professor Emeritus of NAIST and an Invited Professor at Nara Medical University.

 

His research interests include medical image analysis, computer-assisted surgery, and computational anatomy. Dr. Sato is a recipient of the CAOS-International Maurice E. Müller Award for Excellence in Computer Assisted Surgery.

Speech Title: "Next-Generation Computer-Assisted Orthopedic Surgery: AI-Driven Musculoskeletal Image Analysis and Surgical Planning"

 

Abstract: Recent advancements in deep learning and image analysis technologies have enabled high-precision, automated recognition of musculoskeletal structures from medical images. In CT imaging, this allows for the automated, quantitative analysis of individual muscle shape, volume, and density alongside traditional bone metrics. By automatically processing large-scale clinical CT datasets, surgical information, and patient records, this approach provides objective, quantitative support for orthopedic surgical decision-making and planning—domains that have traditionally relied on empirical evaluation.

 

Based on these automated recognition results, we have developed large-scale training datasets to analyze age-related anatomical variations, track disease progression, and automate surgical planning. Furthermore, we are developing AI models to estimate quantitative musculoskeletal parameters directly from plain X-ray images. This framework facilitates complementary preoperative planning and surgical indication assessment using both CT and X-ray imaging, while also enabling low-dose postoperative evaluation and long-term preventive monitoring. In this keynote lecture, we present our musculoskeletal AI analysis infrastructure and discuss its practical applications for next-generation orthopedic surgery support.
