ENCORE: Efficient Noise Context-Aware Representation for Low-Dose CT Denoising
Minwoo Yu, N. Robert Bennett, Jongduk Baek +1
While deep learning-based denoising has become widely adopted in low-dose CT, conventional models use generic architectures designed for natural images, failing to account for non-…
Evaluation of Silicon-Based Photon-Counting CT for Coronary Stenosis Quantification with Realistic Coronary Artery Phantoms
Maria Jose Medrano, Jed Pack, Stephen Araujo +5
Objective: To quantify the impact of high-resolution deep silicon photon-counting CT (dSi-PCCT) on coronary stenosis quantification in anatomically realistic calcified coronary art…
Characterizing the Radiation Dose to Measurement Accuracy Relationship across Multiple Metrics in Opportunistic Chest CT
Boyuan Li, Carolyn C. Chang, Jake J. Kim +5
Objectives: This study aims to characterize the dose-performance relationship for opportunistic CT and disentangle the contributions of segmentation failure and dose-dependent HU b…
End-to-End Differentiable Photon Counting CT
Sen Wang, Yirong Yang, Jooho Lee +2
Quantitative imaging is an important feature of spectral X-ray and CT systems, especially photon-counting CT (PCCT) imaging systems, which is achieved through material decompositio…
Scout-Dose-TCM: Direct and Prospective Scout-Based Estimation of Personalized Organ Doses from Tube Current Modulated CT Exams
Maria Jose Medrano, Sen Wang, Liyan Sun +5
This study proposes Scout-Dose-TCM for direct, prospective estimation of organ-level doses under tube current modulation (TCM) and compares its performance to two established metho…
OpenDosimeter: Open Hardware Personal X-ray Dosimeter
Norah Ger, Alice Ku, Jasmyn Lopez +8
We present OpenDosimeter (www.opendosimeter.org), an open hardware solution for real-time personal X-ray dose monitoring based on a scintillation counter. Using an X-ray sensor ass…
