Aquilion ONE (TSX-306A/3) V10.12 with Spectral Imaging System, Vitrea Software Package, VSTP-001A

The Aquilion ONE (TSX-306A/3) V10.12 system enhances computed tomography by employing advanced methodologies like Deep Learning Reconstruction (PIQE), AI-driven noise reduction (AiCE), and expanded spectral imaging (including dual-energy brain scans) to improve diagnostic image quality, spatial resolution, and reduce radiation dose based on the science of X-ray attenuation and sophisticated image processing. The complementary Vitrea Software Package (VSTP-001A) V8.10 serves the purpose of advanced post-processing, utilizing updated spectral analysis tools to leverage the scanner's enhanced data for detailed material differentiation and sophisticated visualization, facilitating comprehensive clinical assessment.

The Canon Aquilion ONE (TSX-306A/3) V10.12 is a whole-body multi-slice helical CT scanner designed to acquire comprehensive cross-sectional volume datasets, enabling rapid imaging of entire organs like the brain, heart, and pancreas, often in a single rotation. Its methodology centers on advanced image acquisition and reconstruction technologies: PIQE, a Deep Learning Reconstruction algorithm, enhances spatial resolution and reduces noise for cardiac applications; AiCE, a Deep Convolutional Neural Network (DCNN) method, improves overall image quality and reduces noise across various anatomical regions including the abdomen, pelvis, lung, cardiac, brain, inner ear, and extremities. The system also introduces FIRST, an iterative reconstruction algorithm aimed at reducing radiation dose while improving high-contrast spatial resolution. A key scientific advancement is its enhanced spectral imaging system, featuring rapid kV switching for general spectral scans and a new dual-energy scan mode specifically for brain imaging, both designed to differentiate material compositions based on X-ray attenuation differences at distinct energies. Hardware modifications include a new SilverBeam Filter for dose reduction in applications like lung cancer screening, an increased maximum couch-top speed for faster scanning, and a redesigned, more intuitive user console. The Vitrea Software Package (VSTP-001A) V8.10, an application suite for the Vitrea medical image processing platform, provides sophisticated post-processing capabilities for images acquired from various modalities, including CT data from the Aquilion ONE. This software update specifically enhances its Spectral Analysis application to process data from the Aquilion ONE's new dual-energy brain scans (including AiCE-reconstructed images) and integrate segmentation data from Vitrea's CT Myocardial Perfusion and Coronary Artery Analysis tools. The updated Spectral Analysis provides richer visualization options, such as 3D rendering, Chamber View, polar maps, and advanced planar reconstructions (CPR, SPR). Performance testing via phantom studies confirmed the Aquilion ONE's PIQE algorithm provided superior high-contrast spatial resolution (8 lp/cm greater) and noise reduction compared to the previous AIDR 3D algorithm. The SilverBeam Filter was shown to effectively reduce dose while maintaining or improving image quality. Clinical images from the modified Aquilion ONE were confirmed to be of diagnostic quality by a board-certified radiologist. The Vitrea software enhancements were validated through bench testing, confirming they meet specifications and perform as intended for improved image analysis and visualization.
