Comparing CT Scan Organ and Effective Dose Estimates from Radiation Dose Index Monitoring Systems (RDIMs) across Institutions Using a Reference Set of Patient Datasets
Radiation Dose Index Monitoring Systems (RDIMs) can report and track estimated organ and effective doses from CT scans. However, the methods to estimate these doses are not standardized. The purpose of this initial study was to assess the feasibility of perfo...

Inter-Institutional Quantification of Spectral Results with First-Generation Clinical Photon-Counting CT
Photon-counting CT (PCCT) incorporates detector technology that supports quantitative imaging in routine diagnostic evaluation by reducing scanner- and patient-specific effects, thereby enabling more reliable material quantification and characterization. Prev...

Investigating Physics-Based Standardization of Radiomics from Normal and Fibrotic Lung Regions across CT Reconstruction Kernels and Radiation Doses
To investigate whether physics-based radiomics standardization can increase agreement in radiomics extracted from radiologist-annotated regions of diffuse lung disease (DLD) phenotypes across CT reconstruction kernels and radiation doses.

Jacobian-Based Biomechanical Texture Radiomics from Inspiratory–Expiratory CT for Predicting Target-Lobe Volume Reduction and Treatment Response In Endobronchial Valve Therapy
Endobronchial Valves (EBV) are one of the few treatment options for patients with moderate to severe emphysema. Eligibility is typically assessed from CT image data analysis including Emphysema Score (RA950) and Fissure Integrity Score (FIS). However not all...

Pre-Implantation Peri-Valve Jacobian Texture Radiomics As a Biomarker of Endobronchial Valve Treatment Success
Endobronchial Valves (EBV) are one of the few treatment options for patients with moderate to severe emphysema. Eligibility is typically assessed from CT image data analysis including Emphysema Score (Relative Area, RA950) and Fissure Integrity Score (FIS). H...
