A novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...
متن کاملA Method to Improve Electron Density Measurement of Cone-Beam CT Using Dual Energy Technique
PURPOSE To develop a dual energy imaging method to improve the accuracy of electron density measurement with a cone-beam CT (CBCT) device. MATERIALS AND METHODS The imaging system is the XVI CBCT system on Elekta Synergy linac. Projection data were acquired with the high and low energy X-ray, respectively, to set up a basis material decomposition model. Virtual phantom simulation and phantoms...
متن کاملIterative reconstruction optimisations for high angle cone-beam micro-CT
We address several acquisition questions that have arisen for the high cone-angle helical-scanning micro-CT facility developed at the Australian National University. These challenges are generally known in medical and industrial cone-beam scanners but can be neglected in these systems. For our large datasets, with more than 2048 voxels, minimising the number of operations (or iterations) is cru...
متن کاملGeometric Parameters Estimation and Calibration in Cone-Beam Micro-CT
The quality of Computed Tomography (CT) images crucially depends on the precise knowledge of the scanner geometry. Therefore, it is necessary to estimate and calibrate the misalignments before image acquisition. In this paper, a Two-Piece-Ball (TPB) phantom is used to estimate a set of parameters that describe the geometry of a cone-beam CT system. Only multiple projections of the TPB phantom a...
