Elimination of Central Artefacts of L-SPECT with Modular Partial Ring Detectors by Shifting Center of Scanning
Manu Francis, Murat Tahtali, Mark R Pickering
The Lightfield Single Photon Emission Computed Tomography (L-SPECT) system is developed to overcome some of the drawbacks in conventional SPECT by applying the idea of plenoptic im…
Uncertainty Analysis in 3D SPECT Reconstruction based on Probabilistic Programming
Manu Francis, Muhammed Tarek, Mark Pickering +1
Single Photon Emission Computed Tomography (SPECT) is one of the nuclear medicine imaging modalities used for functional analysis of animal and human organs. Gamma rays emitted fro…
Modeling and performance evaluation of stealthy false data injection attacks on smart grid in the presence of corrupted measurements
Adnan Anwar, Abdun Naser Mahmood, Mark Pickering
The false data injection (FDI) attack cannot be detected by the traditional anomaly detection techniques used in the energy system state estimators. In this paper, we demonstrate h…
Adaptive Adjustment of Relaxation Parameters for Algebraic Reconstruction Technique and its Possible Application to Sparsity Prior X-ray CT Reconstruction
Sajib Saha, Murat Tahtali, Andrew Lambert +1
In this paper, we systematically evaluate the performance of adaptive adjustment of the relaxation parameters of various iterative algorithms for X-ray CT reconstruction relying on…
CT Reconstruction from Simultaneous Projections: A Step towards Capturing CT in One Go
Sajib Saha, Murat Tahtali, Andrew Lambert +1
This paper focuses on minimizing the time requirement for CT capture through innovative simultaneous x-ray capture method. The state-of-the-art CT imaging methodology captures a se…
