PET-Adapter: Test-Time Domain Adaptation for Full and Limited-Angle PET Image Reconstruction
Rüveyda Yilmaz, Yuli Wu, Johannes Stegmaier +1
Positron Emission Tomography (PET) image reconstruction is inherently challenged by Poisson noise and physical degradation factors, which are further exacerbated in limited-angle a…
Training-Free Stimulus Encoding for Retinal Implants via Sparse Projected Gradient Descent
Henning Konermann, Yuli Wu, Emil Mededovic +3
Retinal implants aim to restore functional vision despite photoreceptor degeneration, yet are fundamentally constrained by low resolution electrode arrays and patient-specific perc…
Diffusion-based Sinogram Interpolation for Limited Angle PET
Rüveyda Yilmaz, Julian Thull, Johannes Stegmaier +1
Accurate PET imaging increasingly requires methods that support unconstrained detector layouts from walk-through designs to long-axial rings where gaps and open sides lead to sever…
Towards Robust and Generalizable Gerchberg Saxton based Physics Inspired Neural Networks for Computer Generated Holography: A Sensitivity Analysis Framework
Ankit Amrutkar, Björn Kampa, Volkmar Schulz +3
Computer-generated holography (CGH) enables applications in holographic augmented reality (AR), 3D displays, systems neuroscience, and optical trapping. The fundamental challenge i…
