Helical and multislice imaging built great milestones in the history of CT. Aquilion ONE offers the next leap forward in CT technology that will revolutionize patient care. Clinicians have long dreamed of being able to acquire isotropic volumes of an entire organ with a single rotation of the gantry. This leap is possible only with Toshiba's Aquilion ONE, the only scanner with a 320-row detector.
The ability to acquire the entire organs with one volume scan opens the door to new diagnostic possibilities. The neuro ONE protocol allow acquisition of multiple low-dose volume scans of the entire brain during contrast infusion to provide whole brain perfusion and whole brain dynamic vascular analysis in one examination. Dynamic volumetric acquisition protocols can also be used to review moving joint structures in 3D, providing new clinical applications for orthopaedic imaging.
For cardiac examinations, the entire heart can be captured in as little as one rotation for coronary analysis, or over a single heartbeat to include complete functional diagnosis. Each reconstructed 3D volume represents exactly the same phase of the coronary arteries with homogenous contrast enhancement
Faster results, lower dose
The wide coverage provided by the 16 cm wide area detector enables scanning of most of the organs within one rotation, eliminating the need for helical scanning which in turns lowering the dose dramatically. An entire organ can be captured at one time, resulting in ultrafast scan times, which allows the contrast medium dose and exposure dose to be reduced. As well Aquilion ONE¸ incorporates Toshiba’s latest technologies to reduce patient exposure dose, while maintaining high image quality.
- AIDR 3D
- SUREExposure™ 3D Adaptive (automatic exposure control)
- Active Collimator
- Dose Management Functions – Dose Check/Dose Report
With the integration of AIDR 3D into SUREExposure controls, radiation exposure is automatically reduced before the scan, ensuring that the lowest possible dose is employed for the specific diagnostic objective irrespective of the size or shape of the patient. AIDR 3D integrated in SUREExposure 3D Adaptive can be applied to all acquisition modes for routine clinical use and is able to remove up to 50% of image noise resulting, which corresponds to a dose reduction of up to 75% by the same Standard Deviation (SD) for noise.
Key features of AIDR 3D:
- Full integration in scan protocols for improved workflow
- Dose reduction in clinical setting by up to 75%
- Full automatic iterative reconstruction process
- Minimal penalty in reconstruction times
- Noise reduction and improved Spatial Resolution
- Superb artifact suppression
Clinical benefits
Apart from this dramatic dose reduction, there is another important aspect:: cardiac arrhythmia or heart rates up to 130 bpm are no longer an issue as opposed to helical an multislice CT. Online assessment of the imaged RR-interval by the software of the new CT unit ensures that image reconstruction can proceed as planned.
Additionally, if the patient experienced an unexpected extrasystole or if there is insufficient data of one image for artefact-free reconstruction, the scanner will automatically image one additional heartbeat in the same fashion and without any noticeable time-delay.
