采用无与伦比的磁场和磁场梯度功率的全3T性能


提别的3T磁场设计 An exceptional 3T magnet design

The foundation of MAGNETOM Vida is an all-new, exceptional 3T magnet that incorporates aspects of Siemens Healthineers’ ultra-highfield
research scanners. MAGNETOM Vida delivers not only a large Field-of-View, but also excellent homogeneity throughout the entire measurement volume. The result: robust andreliable fat saturation throughout the entireimaging volume, especially important in abdominal or off-center applications. Large Field-of-View applications and long-boneimaging will profit from this as well.

Magnetom Vida 的基础是一个全新的,特别的3T磁铁,它结合了西门子医疗的超高速研究MRI扫描仪的各个方面。Magnetom Vida不仅提供了一个大视场,而且在整个测量容积中提供了很好的均匀性。其结果是:整个成像体积中的脂肪饱和度都是强有力和可靠的,尤其是在腹部或中心外的应用中尤为重要。大视场应用和长骨成像也将从中受益。


新磁场梯度水平 A new level of gradient power

MAGNETOM Vida distinguishes itself with a gradient strength of up to 60/200 simultaneously, powered by the strongest gradient amplifiers
with up to 2.7 MW per axis – offering the power previously only available on 3T research scanners, now in a patient-friendly 70 cm scanner.
Clinical as well as research MRI applications such as diffusion-weighted imaging benefit greatly from powerful gradients through the increased SNR – up to 25% more than with conventional gradient systems – as well as increased scan efficiency5.


Magnetom Vida 以高达60/200的梯度强度来区分自己,它由最强大的梯度放大器提供支持,每轴最高可达2.7 MW - 提供以前只能在3T研究扫描仪上使用的电源,现在使用的是一台对病人友好的70厘米孔径扫描仪。在临床和研究中,磁共振成像的应用,如弥散加权成像,由于信噪比的增加而获得了很大的好处 - 比传统的梯度系统提高了25%,扫描效率也提高了【5】。

Frequalizers 确保长期频率稳定性  Ensure long-term frequency stability with Frequalizers

Demanding applications can induce temperature changes, leading to center frequency shifts and decreased image quality. To avoid this, an

array of temperature sensors ensures stability throughout the entire measurement. The benefit: The scanner always stays on resonance. This

ensures higher consistency and reproducibility of results, especially when it comes to follow-up examinations.



苛刻的应用产生温度变化,会导致中心频率偏移和图像质量下降。为了避免这种情况,一组温度传感器确保整个测量过程的稳定性。好处是:扫描仪总是保持共振。这确保了结果的一致性和重现性,特别是在后续检查方面.






Professor Mike Notohamiprodjo, M.D.,University Hospital Tübingen, Germany “Magnetom Vida 带来了真正的研究系统的性能 -大的FOV和非常强的梯度,并将它与70厘米的内径结合在一起,这对病人来说当然更舒适。“

BioMatrix: a paradigm shift in MRI to sense patient respiration prior to scanning, to adjust to any patient’s body, and to simplify and speed up challenging interactions.

BioMatrix:是磁共振成像的一种模式转变,在扫描前就可以感知病人的呼吸,适应任何病人的不同解剖,并简化和加速具有挑战性的人机相互作用。


BioMatrix是一项新技术,轻松充分发挥3T的潜力

BioMarix技术,结合了西门子公司独特的Tim4G架构的能力,并能够接受每个病人的个性,克服了生物可变性的挑战。在扫描前感觉到病人的呼吸,调整到病人的身体,即使是很难扫描的区域。并且简化病人的处理,不依赖于病人的移动性和扫描区域。VIDA所有的自动执行和集成到BioMatrix传感器,BioMatrix 调节器和BioMatrix 界面。

GPU-accelerated Inline Compressed Sensing

Access patient groups previously excluded from MRI. MAGNETOM Vida redefines 3T performance with a new reconstruction architecture that brings Compressed Sensing applications into the clinical routine. High-quality images based on substantially undersampled data allow for much faster acquisitions, enabling free-breathing examinations in cardiac and abdominal MRI. A powerful reconstruction engine employing parallel GPU computing delivers five times faster【7】 reconstructions of complex compressed sensing data sets, finally making it viable in the clinical routine.


以前被排除在MRI之外的病人组。Magnetom Vida 用一种新的重建架构,重新定义了3T性能,将压缩传感应用纳入临床应用程序。基于大量样本数据的高质量图像可以获得更快的数据,从而能够在心脏和腹部MRI中进行自由呼吸检查。使用并行GPU计算的强大的重建引擎,提供了5倍快的复杂压缩传感【7】数据集的重建速度,最终使其在临床上可行。



Optimizing Total Cost of Ownership


Effective energy management ensures that the exceptional performance of MAGNETOM Vida is provided in a resource-friendly manner.
Intelligent power management solutions, such as magnet cold head EcoPower or disabling of power-consuming components during scan
breaks, contribute to overall energy savings of up to 30% compared to the industry average(COCIR average of MRI vendors8). In addition,
MAGNETOM Vida reduces costs even further – additional construction costs are avoided, since siting requirements are the same as for conventional 70 cm 3T systems.



有效的能源管理确保 Magnetom Vida 的卓越性能以一种资源友好型的方式提供。智能电源管理解决方案,如磁铁冷头EcoPower或在扫描中断期间禁用耗电部件,与行业平均水平相比,总节能高达30% (MRI供应商的COCIR平均值8)。此外,Magnetom Vida 还进一步降低了成本-避免了额外的建筑成本,因为选址要求与传统的70 cm3 T系统相同。
