Evaluate even heavily calcified vessels with photon-counting CT

Quantum PURE Lumen removes calcifications so you can perform coronary CTA exams even in patients with a high Calcium score.

What if you could redefine the clinical pathway for a patient with severe coronary calcifications – potentially keeping them out of the diagnostic cath lab and producing coronary CTA images at high spatial resolution with full spectral information?

With Quantum PURE Lumen on the NAEOTOM Alpha®, it may be possible. Watch the video to learn how.

    Quantum PURE Lumen

    The artifacts resulting from calcifications in arteries can make the evaluation of the true lumen of a vessel impossible. Quantum PURE Lumen removes these calcifications based on the spectral information contained in every voxel of the image.

    What photon-counting means for the future of your department

    The NAEOTOM Alpha with Quantum Technology will redefine CT imaging. Based on the revolutionary direct signal-conversion of its QuantaMax detector, NAEOTOM Alpha offers high-resolution images at minimal dose, improved contrast at lower noise, and breakthrough consistency you’ve never seen before.

    Scan previously excluded patients

    The NAEOTOM Alpha may redefine which patient populations can be addressed with CT. It unlocks patient groups, like those with heavy calcifications, stents, pacemakers, or artificial valves, by offering intrinsic spectral imaging independent of scan speed, and of temporal or spatial resolution.

    Impact treatment outcomes

    Benefit from confident clinical decision-making in cardiology, oncology, and pulmonology, with answers that are meaningful, precise, and reproducible.

    PURE Lumen (Vascular Calcium Removal (VCR)) can be used to measure vessel (e.g., coronary) stenoses by removing the contributions of calcium from images, based on a phantom evaluation (Allmendinger T. et al., 2022, Investigative Radiology).
