Dosimetric Analysis for a Modern 131 Cs Brachytherapy Seed

Conventional LDR brachytherapy seeds rely on internal radiopaque markers that were incorporated to enhance radiographic visibility. With widespread adoption of modern 3D imaging modalities such as CT, the marker presence degrades seed localization and tissue...

Quantitative Assessment of CT Artifact Severity for Cs-131 Brachytherapy Seed Designs with and without a Radiographic Marker

Current LDR brachytherapy seeds contain internal radiopaque markers to enable visibility with radio-graphic imaging. However, this high-Z material introduces artifacts on CT that degrade image quality and may affect seed localization and dosimetric accuracy....
