To develop an automated CT quality control (QC) query system that retrieves, analyzes, and trends QC data and enables image artifact review across iPhone, iPad, and Computer platforms for 71 GE and Siemens CT scanners spanning nuclear medicine, interventional...
Routine CT quality assurance (QA) relies on visual inspection, where subtle non-uniformities can be difficult to identify consistently across scanners and readers. We developed an efficient, interpretable artificial intelligence-assisted tool that detects and...
Accurate PET/CT registration is essential for quantitative cardiac PET. Common approaches include manual rigid registration of CT to PET (MRR) and average CT derived from cine CT (ACT). We evaluated whether data-driven gated PET combined with end-expiration C...
Tin (Sn) spectral filtration improves CT dose efficiency and mitigates beam hardening and photon starvation, two major contributors to metal artifacts that also affect PET attenuation correction. This work presents a comprehensive evaluation of Sn-filtered CT...
