Happy Teachers’ Day! Wishing everyone in our research group success in research and happiness in life!

The manuscript “Self-Cascade Latent Schrödinger Bridge for CT Field-of-View Extension,” authored by Xihao Wu, Jiacheng Liu, Haijun Yu, Andreas Maier, and Yixing Huang, has been accepted by Physics in Medicine & Biology. The study introduces a self-cascade latent Schrödinger bridge (SCL-SB) that combines a two-round shared-weight cascade with a frequency-aware residual mechanism to recover missing peripheral anatomy in truncated CT images while maintaining efficient inference. Congratulations to all the authors!

We are pleased to welcome Tang Jiachen, who has officially joined our group as a master’s student on September 1st, 2026. She completed her bachelor’s degree at School of Computer Science, Beijing Institute of Technology. During her undergraduate studies, she co-authored a paper on explainable medical image analysis as a co-first author, which was accepted to MICCAI 2025, a top-tier conference in medical imaging, and published. The paper also received a conference award. Her current research will focus on the application of quantum computing combined with artificial intelligence in medical imaging, an emerging and interdisciplinary frontier with great potential. We look forward to her innovative contributions and wish her a fruitful and rewarding graduate journey!

Congratulations to Dr. Yu Haijun on the successful approval of the NSFC Young Scientists Fund (Category C) project led by him! The project is titled “Research on Spiral Anode Linear Source Dual-Ring Static CT Imaging.”

Congratulations to Professor Huang Yixing on securing the NSFC General Program grant! The project, titled “Quantum Reconstruction of High-Resolution and High-Precision CT Images in Bit-Constrained Environments,” has been officially approved.

Dr. Huang Yixing was invited to attend the ceremony and delivered a speech as an alumnus representative of the College of Engineering. In his remarks, he reflected on his time as a member of the inaugural undergraduate cohort in Biomedical Engineering, recalling formative experiences such as small-class intensive teaching, an interdisciplinary curriculum, mentorship in undergraduate research, and summer overseas exchange programs. He expressed his gratitude to the School for its meticulous cultivation of students. Drawing on his personal journey, he also shared practical advice with the incoming students on planning their academic paths.

Many thanks to the Beijing Natural Science Foundation Committee and Beijing Langshi Instrument Co., Ltd. for their strong support! I would also like to express my sincere gratitude to our team members Yu Haijun and Liu Yujie for their significant contributions to the project application.

Our graph-guided 3D Gaussian framework, featuring denoised initialization and pixel-graph-aware densification to suppress sparse-view artifacts in cone-beam CT reconstruction, has been successfully published in IEEE Transactions on Computational Imaging.

The graduate course “Advanced Medical Artificial Intelligence,” led by Professor Huang Yixing, has successfully received funding from Peking University’s 2025 Graduate Course Development Initiative! The funding amount for each course is 20,000 RMB. In the fall of 2025, the “Advanced Medical Artificial Intelligence” course attracted 178 students from various departments and affiliated hospitals of Peking University Health Science Center in its first offering, far exceeding expectations. The course quality has been highly praised by both faculty and students. Special thanks to every lecturers for their tremendous support!

Congratulations to Zuodong Zhong on receiving the 2025 Baosteel Outstanding Student Award! Established in 1990 by Baosteel and administered under China’s Ministry of Education, the Baosteel Education Award is one of the most prestigious nationwide education honors in China, covering more than 120 universities across 31 provinces and recognizing roughly 500 outstanding students nationwide each year. At the University of Science and Technology Beijing (USTB), the award is selected university-wide across all majors and grade levels, with only two undergraduate recipients granted annually — making it one of USTB’s most competitive student honors. Zuodong is a senior undergraduate majoring in Automation at USTB’s School of Automation and Electrical Engineering, and will join our group for his graduate studies. The award has been officially featured by USTB’s WeChat public account: https://mp.weixin.qq.com/s/BIi0fDSpUGNLGTRJJCXMlg. We warmly congratulate Zuodong on this remarkable recognition and look forward to welcoming him to the lab.

Congratulations to Hongrun Dong on completing his master’s thesis and starting a new position at United Imaging Healthcare as a Clinical Application Specialist (CAS). His M.Sc. thesis is entitled “Deep Learning for Cone-Beam CT Field-of-View Extension.” The thesis was supervised by Yixing Huang, together with Florian Putz and Andreas Maier. This work focuses on projection-domain completion and outpainting for truncated CBCT projections to improve downstream reconstruction quality. Best wishes to Hongrun for a great start and continued success in his new role.

We are delighted to welcome Dr. Meng Li to join our research group as a postdoctoral researcher on April 1st, 2025. Dr. Li focus on establishing multimodal MRI-based methodologies to assess brain diseases and identify potential biomarkers associated with neuropsychiatric disorders, and her research will further promote our exploration in the field of medical image analysis.
