4D Cine Cinematic Rendering of Cardiac Devices: Feasibility Tied to Metallic Burden

Four-dimensional cine cinematic rendering (CR) of implanted cardiac devices showed feasibility inversely related to metallic burden: low-metal nitinol and catheter devices rendered well, but high-metal LVAD housings were substantially degraded by streak artifact. Observation fro…

• The study is an illustrative technical experience, not a systematic evaluation of diagnostic performance.
• The inverse relationship between metallic burden and rendering quality was observed qualitatively and should be considered preliminary.
• Future directions include photon-counting detector CT, metal artifact reduction, and AI-assisted post-processing.
