The Toshiba Aquilion ONE is a premium, high-end Dynamic Volume Computed Tomography (CT) scanner widely recognized for introducing the medical industry to true single-rotation, whole-organ imaging. Originally engineered by Toshiba Medical Systems, this system revolutionized diagnostics by scanning entire anatomical structures—like the heart or brain—in a single pass without needing to "stitch" multiple images together.

Below is a detailed breakdown of its core specifications, key features, clinical applications, and variants.

Key Specifications & Architecture

Detector Coverage: Features a massive 16 cm (160 mm) area detector row coverage in a single gantry rotation.
Slice Capabilities: Utilizes a 320-row detector system that generates up to 640 slices per rotation via advanced reconstruction algorithms (like coneXact).
Rotation Speed: Blazing fast rotation times as low as 0.275 seconds, providing elite temporal resolution.
Gantry Design: Equipped with a spacious 78 cm wide bore and a 30° gantry tilt to maximize patient comfort and simplify trauma access.
Table Capacity: Robust patient couch capable of supporting up to 660 lbs (approx. 300 kg) with optional lateral slide features.

Core Technology & Features

Dynamic Volume CT (DVCT): Enables continuous 4D video acquisition to capture not just anatomy, but real-time organ movement, joint articulation, and physiological blood flow.
Single-Heartbeat Cardiac Capture: Captures the entire coronary architecture in a single beat, effectively eliminating motion artifacts from irregular heart rates.
Advanced Radiation Dose Reduction: Integrates Adaptive Iterative Dose Reduction (AIDR 3D) and Model-Based Iterative Reconstruction (MBIR), which lower radiation exposure by up to 84.6% while maintaining sharp image clarity.
PUREViSION Optics: Built with high-efficiency detectors that improve light output by 40%, optimizing the use of X-ray photons to protect patients.
Dual-Energy Imaging: Enhances tissue characterization, making it easier for clinicians to isolate contrast agents, differentiate material compositions, and evaluate complex tumors.
