See clearly and navigate efficiently when treating cerebral aneurysms


Visualizing new, less opaque devices presents new challenges during treatment planning and device placement, which can lengthen your procedure time. That makes superb 2D and 3D imaging more important than ever to guide treatment decisions and device placement, and to efficiently manage radiation dose.

Azurion 7 B20/15

Azurion 7 B20/15 Image-guided therapy biplane system

High-quality neuro-specific 39 cm (15 in) lateral detector that can be positioned close to the patient’s head while providing full brain coverage

Secure and fast parking of the lateral gantry allows for a seamless switch between 2D and 3D image acquisition

Image beam rotation assures patient-oriented images from every angulation and rotation, eliminating the need to pivot the table or reposition the patient

Positioning the frontal arc at 135 degrees enables optimal head-end access to the patient and accommodates ideal working positions

AneurysmFlow blood flow patterns visualization

Asses the impact of flow diverters immediately in the angio suite

Being able to immediately assess the impact of flow diverters on blood flow is crucial during treatment. AneurysmFlow converts information from a SmartCT Angio acquisition and 2D DSA flow sequences into quantitative flow values. These values are used to visualize and quantify blood flow patterns before and after flow diverter deployment in cerebral aneurysms.

SmartCT Angio

High-resolution 3D visualization from a single rotational angiography run

SmartCT Angio is an X-ray acquisition technique that generates a complete high-resolution 3D visualization of cerebral vasculature from a single rotational angiography run – all controlled via the touchscreen at the table. This can improve visibility of tortuous or complex anatomy that may not be seen on a 2D or DSA image.

    Clinical solutions for treating cerebral aneurysms

    Infographic image

    Visualize lesion boundaries and corresponding vascularization

    MR-CT roadmap

    MR-CT Roadmap allows you to overlay a previously acquired SmartCT Angio or MR angio scan with live fluoroscopy to visualize lesion boundaries and corresponding vascularization for risk assessment. Re-using pre-acquired data helps you manage X-ray dose and contrast medium.

    Clearly view brain perforators and challenging devices

    SmartCT Vaso IA

    Enhance visualization of endovascular stents, flow diverters and other devices, as well as vessel morphology down to the perforator level with SmartCT Vaso. This acquisition technique is based on a cone beam CT (CBCT) scan and an intra-arterial contrast injection. It is increasingly used for follow-up of aneurysms treated with flow-diverter stents to check device positioning.

    Navigate precisely using dynamic 3D image guidance

    SmartCT roadmap enhanced visualization

    SmartCT Roadmap enhances visualization of overlapping vessels to support precise navigation of guidewire and catheter through complex vasculature. Offers high-level precision with real-time compensation for gantry, table and small patient movements.

    Visualization of blood flow patterns helps to support accuracy

    MR-CT roadmap

    AneurysmFlow helps to visualize and quantify blood flow patterns in the parent vessel and aneurysm sac to obtain key information that can assist deployment of flow diverters and other embolization devices.

    Improve visibility of cerebral vasculature

    Roadmap pro

    Roadmap Pro is an advanced double-contrast roadmap that helps improve visibility of overlapping vessels while balancing radiation exposure. It can be customized to show advancement during coil placement.

    Visualize tortuous pathologies in high-fidelity 3D

    SmartCT Angio

    SmartCT Angio provides a volumetric view in a few seconds1 to assist assessment of location, size, neck and severity of aneurysm for treatment planning. 3D volumes are visualized with high spatial resolution and automatic patient movement compensation.

    Check for bleeds peri-procedure

    CBCT (CT-like)

    Use SmartCT Soft Tissue imaging in the Neurovascular suite to check treatment success and identify bleeds.

    Calculate blood flow post-treatment

    Aneurysm flow post treatment

    AneurysmFlow evaluates changes in blood flow in the aneurysm, by calculating the change in Mean Aneurysm Flow Amplitude (MAFA ratio) before and after flow diverter placement.

    Workflow innovations to treat cerebral aneurysms efficiently


    Azurion offers a number of workflow innovations designed to help staff work efficiently and easily, while maintaining a single-minded focus on the patient and managing radiation dose.

    Azurion Biplane B20/12

    Sharp, motion-free vessels at low dose

    ClarityIQ wheel

    ClarityIQ technology reduces patient dose by 75% in neuro DSA,2 while maintaining equivalent image quality, compared to a system without ClarityIQ. Its automatic motion compensation removes skull and motion artifacts, which is key when placing small devices at the base of the skull.

    Unlimited imaging flexibility

    Image beam rotation

    Image beam rotation assures patient-oriented images from every angulation and rotation, eliminating the need to pivot the table or reposition the patient.

    Full tableside control

    FlexVision Pro

    Gives you direct access and full control of pre-operative diagnostic scans, patient information and planning tools at tableside to save time and unnecessary walking in and out of the sterile area.

    Reduce in-lab prep time, supported by ProcedureCards

    ProcedureCards image

    ProcedureCards3 streamline and standardize system set-up and help reduce preparation errors. Select the Aneurysm ProcedureCard and the system is set up the way you want.

    Use neuro headrest to help reduce motion artifacts

    Neuro headrest

    Can be used to restrain restless patients under conscious sedation to help reduce motion artifacts during the procedure.

    Patient-oriented images from every angulation 

    Fast parking SmartCT

    Secure and fast parking of the lateral gantry allows for a seamless switch between 2D and 3D image acquisition without workflow interruption.
