  journal={arXiv: Medical Physics},
In the calculation of Positron Emission Tomography (PET) image reconstruction, System Response Matrix (SRM) characterizes the numerical relationship between measurement space and image space. Due to a significant amount of calculation and low efficiency of the current SRM algorithm, the application of iterative reconstruction in the medical and industrial fields is limited. The time and space of computing SRM are the most important factors that researchers are concerned about. In this paper…

System response matrix denoising in measurement space in positron emission tomography

This work investigates the impact of a denoising filter applied to the SRM elements of a short-time simulated SRM on the image quality and quantitative information accuracy and shows that a 1D mean filter applied longitudinally to profiles extracted from every volume of response produces better noise performance than the unfiltered SRM.

Spatial resolution recovery utilizing multi-ray tracing and graphic processing unit in PET image reconstruction

This work implemented an analytical method to model system matrix for resolution recovery, which was then incorporated in PET image reconstruction on a graphical processing unit platform, due to its parallel processing capacity.

High throughput CUDA implementation of accurate geometric modelling for iterative reconstruction of PET data

An approach to high throughput and high accuracy modelling of the geometric component of PET acquisition for the Siemens Biograph mMR PET/MR scanner is presented, allowing the use of ray and voxel-driven methods optimal for forward and back-projection, respectively.

A new exact algorithm is presented that considers the CT data as consisting of the intersection volumes of three orthogonal sets of equally spaced, parallel planes, for a three-dimensional CT array of N3 voxels.

Fast projection algorithm for voxel arrays with object dependent boundaries

One-pass list-mode EM (OPL-EM), previously named ROPLE, is a new list-mode iterative reconstruction algorithm for high resolution, high count-rate and large field of view (FOV) PET scanners. The

MRI-guided brain PET image filtering and partial volume correction

Positron emission tomography (PET) image quantification is a challenging problem due to limited spatial resolution of acquired data and the resulting partial volume effects (PVE), which depend on the

A projection access order for speedy convergence of ART (algebraic reconstruction technique): a multilevel scheme for computed tomography.

The authors report here a scheme that yields the most efficient reconstruction without orthogonalization: projections are organized and accessed in a nominally multilevel fashion, and is better in image quality than the Fourier back-projection algorithm, at least for a smaller number of projections.

3D Forward and Back-Projection for X-Ray CT Using Separable Footprints

Simulations and experiments showed that both new separable footprint (SF) projector methods are more accurate than the distance-driven (DD) projector, which is a current state-of-the-art method in the field.
