Differentiable Forward and Back-Projector for Rigid Motion Estimation in X-ray Imaging
Xiao Jiang, Xin Wang, Ali Uneri +2
Objective: In this work, we propose a framework for differentiable forward and back-projector that enables scalable, accurate, and memory-efficient gradient computation for rigid m…
Stationary CT Imaging of Intracranial Hemorrhage with Diffusion Posterior Sampling Reconstruction
Alejandro Lopez-Montes, Thomas McSkimming, Anthony Skeats +4
Diffusion Posterior Sampling (DPS) can be used in Computed Tomography (CT) reconstruction by leveraging diffusion-based generative models for unconditional image synthesis while ma…
Image Guidance for Robot-Assisted Ankle Fracture Repair
Asef Islam, Anthony Wu, Jay Mandavilli +2
This project concerns developing and validating an image guidance framework for application to a robotic-assisted fibular reduction in ankle fracture surgery. The aim is to produce…
Penalized-Likelihood Reconstruction with High-Fidelity Measurement Models for High-Resolution Cone-Beam Imaging
Steven Tilley, Matthew Jacobson, Qian Cao +4
We present a novel reconstruction algorithm based on a general cone-beam CT forward model which is capable of incorporating the blur and noise correlations that are exhibited in fl…
High-Fidelity Modeling of Shift-Variant Focal-Spot Blur for High-Resolution CT
Steven Tilley, Wojciech Zbijewski, J. Webster Stayman
Dedicated application-specific CT systems are popular solutions to high-resolution clinical needs. Some applications, such as mammography and extremities imaging, require spatial r…
Modeling shift-variant X-ray focal spot blur for high-resolution flat-panel cone-beam CT
Steven Tilley, Wojciech Zbijewski, Jeffrey H. Siewerdsen +1
Flat-panel cone-beam CT (CBCT) has been applied clinically in a number of high-resolution applications. Increasing geometric magnification can potentially improve resolution, but a…
