Physics-Guided Dual-Domain Plug-and-Play ADMM for Low-Dose CT Reconstruction
Sayantan Dutta, Sudhanya Chatterjee, Ashwini Galande +2
Ultra-low-dose CT (ULDCT) imaging can greatly reduce patient radiation exposure, but the resulting scans suffer from severe structured and random noise that degrades image quality.…
Automated Motion Artifact Check for MRI (AutoMAC-MRI): An Interpretable Framework for Motion Artifact Detection and Severity Assessment
Antony Jerald, Dattesh Shanbhag, Sudhanya Chatterjee
Motion artifacts degrade MRI image quality and increase patient recalls. Existing automated quality assessment methods are largely limited to binary decisions and provide little in…
Test Time Optimized Generalized AI-based Medical Image Registration Method
Sneha Sree C., Dattesh Shanbhag, Sudhanya Chatterjee
Medical image registration is critical for aligning anatomical structures across imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), and ultrasou…
Structure-Aware Adaptive Kernel MPPCA Denoising for Diffusion MRI
Ananya Singhal, Dattesh Dayanand Shanbhag, Sudhanya Chatterjee
Diffusion-weighted MRI (DWI) at high b-values often suffers from low signal-to-noise ratio (SNR), making image quality poor. Marchenko-Pastur PCA (MPPCA) is a popular method to red…
LSST: Learned Single-Shot Trajectory and Reconstruction Network for MR Imaging
Hemant Kumar Aggarwal, Sudhanya Chatterjee, Dattesh Shanbhag +2
Single-shot magnetic resonance (MR) imaging acquires the entire k-space data in a single shot and it has various applications in whole-body imaging. However, the long acquisition t…
