The Aquilion ONE scanner – A major advance in dynamic volume imaging
The Aquilion ONE from Toshiba Medical Systems is a true revolution in medical imaging. The world's first scanner to offer 16 cm coverage in a single rotation, it enables dynamic volume acquisition of entire organs with unrivalled temporal homogeneity. With this technology, the Aquilion ONE is redefining the standards of computed tomography (CT) diagnostics, particularly in neurology, cardiology, oncology and paediatric imaging.
In neurology, it enables complete cerebral perfusion to be performed in a single acquisition, which is essential in the rapid treatment of strokes. 4D DSA (dynamic CT angiography) technology provides detailed visualisation of intracranial circulation, effectively replacing invasive DSA examinations. In less than 60 seconds, it is possible to identify areas of ischaemia or impaired perfusion, while reducing radiation exposure to approximately 6 mSv with only 50 mL of contrast agent.
In cardiology, the Aquilion ONE stands out for its ability to capture the entire heart in a single beat, with a rotation time of 0.35 seconds. This enables high-resolution imaging without motion artefacts, even in cases of arrhythmia. Coronary examinations benefit from SURESubtraction™ technology, which removes calcium and stents from images, providing clear visualisation of the lumen without overdosing the patient. The scanner is also capable of performing ECG-gated acquisitions without additional dose thanks to the wide-volume technique.
Dynamic imaging is not limited to the heart or brain. The Aquilion ONE offers innovative applications in oncology, such as liver or lung perfusion, which are useful for assessing tumour vascularisation or response to treatment. The detection and characterisation of lung nodules is greatly improved thanks to dynamic perfusion analysis, which effectively differentiates between benign and malignant tumours.
Another strong point is its use in paediatrics. Thanks to ultra-fast acquisitions (up to 350 ms), the scanner avoids the need for anaesthesia in most cases. Its volume sensor captures high-resolution images in a single rotation, limiting artifacts related to respiratory movement or agitation. In ENT, cardiac and thoracic imaging, it offers exceptional performance with very low doses, adapted to the morphology of children.
Finally, the system incorporates the latest advances in dose reduction with AIDR 3D (Adaptive Iterative Dose Reduction), which automatically adapts the exposure parameters to each patient. The integrated planning software and post-processing tools ensure a smooth workflow, suitable for demanding hospital environments.
The Aquilion ONE is more than just a CT scanner: it is a next-generation dynamic imaging platform designed to improve patient care, speed up diagnosis and optimise patient safety. Whether for emergency, follow-up or clinical research examinations, the Aquilion ONE represents a strategic investment for healthcare facilities seeking performance, precision and innovation.
