I am a fourth-year undergraduate student studying computer science and technology at Hangzhou Dianzi University where I am advised by Prof. Ruiquan Ge and Prof. Changmiao Wang. And I plan to pursue my master’s degree at the Laboratory of Image Science and Technology, School of Computer Science and Engineering, Southeast University, Nanjing, and also with the Key Laboratory of New Generation Artificial Intelligence Technology and Its Interdisciplinary Applications (Southeast University), Ministry of Education, China, advised by Prof. Yikun Zhang specialized in Diffusion Model-Based CT Metal Artifact Reduction (MAR).

I have a broad interest in deep learning models, with a primary focus on medical image analysis. I am also an enthusiastic self-learner and interested in various fields of computer science. Currently, I am interning at Hikvision Research Institute, focusing on Deep Learning-Based 3D Depth From Focus for Extended Depth-of-Field Microscopy.

BS-LDM: Effective Bone Suppression in High-Resolution Chest X-Ray Images with Conditional Latent Diffusion Models

We propose an end-to-end framework BS-LDM for suppressing bones in high-resolution CXR images, improving soft tissue clarity with advanced diffusion models and hybrid loss strategies. Its clinical value is validated using the SZCH-X-Rays and processed JSRT datasets.

BS-Diff: Effective Bone Suppression Using Conditional Diffusion Models from Chest X-Ray Images

We propose a new bone suppression framework called BS-Diff, which utilizes a conditional diffusion model and a U-Net architecture to generate high-quality soft tissue images with high bone suppression rates.

UWAFA-GAN: Ultra-Wide-Angle Fluorescein Angiography Transformation via Multi-scale Generation and Registration Enhancement

This paper is an enhanced version of our previous method UWAT-GAN. It can be used to turning UWF scanning laser ophthalmoscopy(UWF-SLO) to the UWF fluorescein angiography(UWF-FA) and display the tiny vascular lesion areas. And it could be trained on a little misalignment paired UWF-SLO and UWF-FA.
