TsingPai Forum-Master Lecture｜Professor Ma Zeng of Tsinghua University visited Medical College

Original TsingPAI Guangsheng Qingpai Guangsheng

On January 9, 2024, Ma Zeng, Founder/Chief Scientist of Beijing Qingpu Technology Co., Ltd, Associate Professor/Doctoral Supervisor of the Department of Electronic Engineering of Tsinghua University, was invited to visit the School of Medicine of Overseas Chinese University (OCU), to discuss and exchange ideas with experts and scholars of the School of Medicine of OCU, and to give a lecture titled Optoacoustic Imaging and Its Biomedical Applications. Wang Suliang, Secretary General of Medical-Industrial Platform of Tsinghua Straits Research Institute, Tu Xiaoguang, Deputy Director of Medical-Industrial Collaborative Innovation Center of Tsinghua Straits Research Institute, and Wang Xiaojun, Founder/CEO of Beijing Qingpai Science and Technology Company, visited and participated in the exchange together.

The symposium was hosted by Prof. Diao Yong, Dean of the College of Medicine of Overseas Chinese University (OCU), Mr. Li Zhaofa, Vice Dean of the College of Medicine of OCU, and some of the faculty members and postgraduate students of the College of Medicine participated in the seminar through both offline and online means.

In this lecture, Prof. Ma Zeng introduced the development history of biophotonics, photoacoustic molecular imaging technology and its industrialization, and detailed the application of photoacoustic imaging technology in clinical diagnostic and therapeutic researches, such as the diagnosis of inflammatory diseases (e.g., Crohn's disease, rheumatoid arthritis), and diagnostic and therapeutic treatments of tumors (e.g., colorectal cancer, breast cancer).

In addition, Prof. Ma also introduced the application of photoacoustic imaging in observing organs and tissue structures (e.g., brain, liver, kidney) in experimental animals, as well as its cutting-edge research results in quantitative measurement of physiological indices such as blood oxygenation, lipids, collagen, and so on. These studies continue to drive the innovation of photoacoustic imaging in medical diagnosis and treatment.

Afterwards, Prof. Ma introduced PIIP, the latest achievement of TsingPai in the field of photoacoustic imaging, which is a comprehensive photoacoustic imaging platform equipped with high-performance 360° omnidirectional ring array sensors, a life support system for mouse models, and highly expandable and integrated interfaces, and is designed for scientific research. The PIIP series photoacoustic integrated imaging platforms feature high-performance 360° omnidirectional ring array transducers, life support systems for mouse models, and highly expandable interfaces. The platform can be used for structural and functional imaging of biological tissues, which facilitates the study of the morphological structure, physiological characteristics, and metabolic functions of biological tissues. Experiments can be carried out conveniently through in vivo, real-time, non-invasive optical imaging.

After the lecture, all the experts and scholars present had a lively discussion on photoacoustic imaging technology and application. Professor Xie from the School of Medicine of Overseas Chinese University proposed: "We expect that photoacoustic imaging technology will solve the problem of crosstalk color coverage during multicolor imaging currently encountered in scientific research. And we hope to promote the application of this technology in the field of organic small molecule anti-tumor drug design and fluorescent probe molecular research through follow-up exchanges and cooperation."

Finally, Dean Diao Yong of Overseas Chinese University School of Medicine summarized, "Photoacoustic imaging technology is an emerging imaging modality in recent years with a wide range of application scenarios. It is hoped that the UWM School of Medicine team can work closely with the technical teams of Tsinghua and Qingpu in related fields to accelerate the scientific research and innovation of this technology in the biomedical field."
