李建初

Li Jianchu's publicly available information is limited, and a complete account of his identity and career is not available. The four works collected here nonetheless make his professional focus on ultrasound medicine clear. He took part in writing or compiling Ultrasound Difficult Case Analysis at Peking Union Medical College Hospital, Handbook for Critical Value Management in Ultrasound, Quality Control Management Standards for Ultrasound Medicine, and Practice and Exploration of the Ultrasound Medicine Teaching Base at Peking Union Medical College Hospital. These works address difficult case analysis, critical value management, quality control standards, and the development of a teaching base, covering key aspects of ultrasound clinical practice, safety management, and professional training. Drawing largely on clinical and teaching practice at Peking Union Medical College Hospital, they reflect a practical, standards-oriented approach that emphasizes operating procedures and institutional development. They are suited to ultrasound physicians, technologists, and related administrators, and are of practical value in promoting standardization and teaching system development in ultrasound medicine.
