Transforming CT
Aquilion ONE / GENESIS Edition goes beyond the evolution of dynamic volume CT. Intensive, clinically focused research and innovative technological developments have culminated in a CT system with 16 cm z-axis coverage at 0.5 mm resolution and reduced radiation dose requirements¹.
Now available on Aquilion ONE / GENESIS Edition, Advanced intelligent Clear-IQ Engine (AiCE) is an innovative approach to CT reconstruction that leverages Deep Learning Neural Networks specifically trained to perform one task—reconstruct images that are sharp, clear, and distinct.
¹When AIDR 3D Enhanced and or FIRST Model-based Iterative Reconstruction are used.
Brain Aneurysm Coiling, SEMAR
Aquilion ONE / GENESIS Edition
53-year-old female underwent head endovascular treatment. A follow-up head CTA was performed. The high attenuation material used for treatment causes extensive streak artifact. SEMAR, Single Energy Metal Artifact Reduction was applied to the scan. 3D Volume Rendered and Multiplanar Reconstruction (MPR) demonstrate minimized artifact caused by the metallic implant. SEMAR provides better visualization of the soft tissue and vasculature surrounding it.

Brain Cerebral Aneurysm, SURESubtraction
Aquilion ONE / GENESIS Edition
41-year-old female presented with headaches and family history of brain aneurysms. A head CT without contrast followed by a CT Angiogram with SURESubtraction was requested to rule out the presence of an aneurysm. 3D Volume Rendered, Multiplanar Reconstruction (MPR) and Maximum Intensity Projection (MIP) demonstrate an aneurysm arising from the right ICA. SURESubtraction shows with clarity the aneurysm free from overlying bone.

Brain Perfusion Extracranial AVM
Aquilion ONE / GENESIS Edition
A dynamic 4D CTA DSA and whole brain perfusion was performed. Dynamic Volumetric 3D Volume Rendered and Maximum Intensity Projection (MIP) demonstrate an extracranial supraorbital arteriovenous malformation (AVM). 3D VR and Multiplanar Reconstruction (MPR) cerebral perfusion maps are also demonstrated.
