Aquilion ONE (TSX-308A/3) V1.5

The Canon Medical Systems Corporation's Aquilion ONE (TSX-308A/3) V1.5 is a whole-body multi-slice helical CT scanner engineered to acquire and display comprehensive cross-sectional volumes for specialized diagnostic studies. It achieves this through advanced scientific methodologies, including deep learning reconstruction algorithms (FIRST, AiCE, PIQE, CLEAR Motion) for image quality enhancement and dose reduction, alongside a spectral imaging system for material analysis.

The Canon Medical Systems Corporation's Aquilion ONE (TSX-308A/3) V1.5 is a whole-body multi-slice helical computed tomography (CT) scanner, deemed substantially equivalent to existing predicate devices, designed to acquire and display detailed cross-sectional volumes across the entire body, including whole organs. Its primary purpose is to enable trained physicians to conduct specialized diagnostic studies effectively. This system integrates several advanced features and algorithms, including FIRST for optimizing dose and spatial resolution, AiCE for effective noise reduction, and a spectral imaging system for detailed material composition analysis. Furthermore, it incorporates Deep Learning Reconstruction methods, PIQE and CLEAR Motion, specifically engineered to further enhance spatial resolution and mitigate motion artifacts. The device's robust safety and effectiveness were rigorously established through adherence to quality system regulations, conformance to applicable performance standards, and extensive testing, encompassing both bench evaluations and expert clinical image reviews by certified radiologists, all confirming its high diagnostic quality.
