DukeSim v1.2

Description

DukeSim v1.2 is a GPU-based CT simulator that generates CT projection and reconstruction images of a given voxelized computational phantom.

Capabilities for DukeSim v1.2:

• Ray-tracing module for primary signal
• Monte Carlo for scatter
• Estimates dose
• Helical and axial acquisitions
• Focal spot wobbling (flying focal spot)
• Beam hardening correction
• Tube current modulation
• Simulates both energy-integrating and photon counting detectors
• Dual-source/dual-energy simulations
• Integrated with MCR Toolkit for filter-back projection (FBP) based reconstruction

NEW FEATURES:

• Integration of a reconstruction tool (MCR toolkit)
• Supports a web-based graphical user interface

Inputs:

• Voxelized computational phantom and corresponding material file
• Acquisition geometry
• X-ray spectrum file (including bowtie filter)
• Detector response file
• A parameter file including the acquisition protocol

Outputs:

• Sinogram images
• Reconstructed images
• Dose estimates
