Fast polyenergetic forward projection for image formation using OpenCL on a heterogeneous parallel computing platform
Abstract
Simulated projection images of digital phantoms constructed from CT scans have been widely used for clinical and research applications but their quality and computation speed are not optimal for real‐time comparison with the radiography acquired with an x‐ray source of different energies. In this paper, the authors performed polyenergetic forward projections using open computing language (OpenCL) in a parallel computing ecosystem consisting of CPU and general purpose graphics processing unit (GPGPU) for fast and realistic image formation.
