Abstract: Professor Wang Zhenchang is the first academician of the Information and Electronic Engineering Division of the Chinese Academy of Engineering in the health field. As a leading figure in the field of image perception and analysis of auditory and visual systems, He has long been engaged in scientific research of physiological and pathological information detection, perception technology, and instruments. His major academic achievements include: ①Breaking through the limitations of traditional imaging relying on single-structure information diagnosis, he established a new paradigm for a multi-modal and multi-dimensional coordinated diagnostic system for complex human system images and a physiological-pathological multi-element information correlation diagnosis system. Further, he created a multi-element coordinated perception method for auditory conduction pathways to clarify the mechanism and causes of pulsatile tinnitus, which led international frontier research in this direction. ②Overcoming the difficulty of accurately identifying tiny human structures, he was in charge of the development of the world's first bone-specific computed tomography (CT) instrument with a resolution of 50 μm, promoting information acquisition capability from sub-millimeter to tens of micrometers. This successfully explored a new high-performance development path for specialized and refined domestic CT instruments. ③ Based on the integration of information technology and medicine, he significantly improved the detection efficiency of small lesions in the auditory and visual systems and advanced the reconstruction of medical imaging. Many of his research results have been included in international consensus, textbooks, and national unified teaching materials, and it has also been widely applied in the clinical practice, beneficial to hundreds of millions of patients.
