Universal Topology Refinement for Medical Image Segmentation with Polynomial Feature Synthesis

no code implementations15 Sep 2024 Liu Li, Hanchun Wang, Matthew Baugh, Qiang Ma, Weitong Zhang, Cheng Ouyang, Daniel Rueckert, Bernhard Kainz

Directly training a post-processing model to mitigate topological errors often fails as such models tend to be biased towards the topological errors of a target segmentation network.

Stability and Generalizability in SDE Diffusion Models with Measure-Preserving Dynamics

no code implementations19 Jun 2024 Weitong Zhang, Chengqi Zang, Liu Li, Sarah Cechnicka, Cheng Ouyang, Bernhard Kainz

We uncover several strategies that inherently enhance the stability and generalizability of diffusion models for inverse problems and introduce a novel score-based diffusion framework, the \textbf{D}ynamics-aware S\textbf{D}E \textbf{D}iffusion \textbf{G}enerative \textbf{M}odel (D$^3$GM).

Weakly Supervised Learning of Cortical Surface Reconstruction from Segmentations

Conditional Temporal Attention Networks for Neonatal Cortical Surface Reconstruction

1 code implementation21 Jul 2023 Qiang Ma, Liu Li, Vanessa Kyriakopoulou, Joseph Hajnal, Emma C. Robinson, Bernhard Kainz, Daniel Rueckert

The importance of each SVF, which is estimated by learned attention maps, is conditioned on the age of the neonates and varies with the time step of integration.

Recovering medical images from CT film photos

no code implementations10 Mar 2022 Quan Quan, Qiyuan Wang, Yuanqi Du, Liu Li, S. Kevin Zhou

While medical images such as computed tomography (CT) are stored in DICOM format in hospital PACS, it is still quite routine in many countries to print a film as a transferable medium for the purposes of self-storage and secondary consultation.
