DukeSim v1.1

Description

DukeSim v1.1 is a GPU-based CT simulator that generates CT projection images of a given voxelized computational phantom.

Capabilities for DukeSim v1.1:

• 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

NEW FEATURES:

• Dual-source/dual-energy simulations
• Photon-counting simulations

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
• Dose estimates
