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...

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...

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.

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...

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...

To propose a Graph Neural Network (GNN) framework that explicitly models liver vessel topology to detect anatomical landmarks and reconstruct anatomically consistent segments.
