Photon-counting CT (PCCT) denoising seeks to approximate high-dose image quality from lower-dose acquisitions. A key challenge for patient-specific denoising with precise control of denoising strength is the lack of an available ground-truth “target” image wh...

A Quality Improvement Initiative Employing Size-Based Reference Levels for Monitoring CT Dose Appropriateness
CT reference levels are mandated by Texas state regulations, and Medical Physics is responsible for reviewing CT studies that exceed these levels and determining the cause. The current clinical reference level for body CT, 60mGy, is applied uniformly across a...

BEST IN PHYSICS (IMAGING): A Patient-Specific, Target NPS-Driven Noise Insertion Framework for Photon-Counting CT Denoising
Photon-counting CT (PCCT) denoising requires paired images with different noise levels for supervised training, but acquiring such data is rarely feasible due to increased radiation exposure and registration challenges. As a result, low-dose–like data are gen...
