西门子推出速度向量超声波检查设备

 
速度向量成像扫描方法是一种用于评估心肌机械性能的很有前途的新工具，是过去3年里由心血管专家和物理学家开发的运动分析方法。这种检查能够提供更加精细的心肌收缩和运动数据，可以用于评估充血性心衰、心肌同步功能紊乱、以及其他心肌功能障碍患者的心脏解剖学。

速度向量目标可以用于任何传感器，包括心血管目标包括儿科、成人、跨食管(TEE)、心内超声心动图、血管和胎儿应用。

Siemens医疗解决方案公司(Erlangen, Germany)介绍了这种新工艺，在2005年9月瑞典斯德哥尔摩举行的欧洲心血管年会上推出了Acuson Sequoia超声心动图检查平台，还展示了Acuson AcuNav 8F超声导管。

AcuNav 8F横断面比现在使用的AcuNav 10F导管面积小33％，能够在所有患者中特别是较小患者、左心脏电生理检查和介入心脏病学中进行改良评估。“心脏手术的趋势是创伤性较小的手术，从开放手术到小孔进入，现在是导管为基础的手术，而这需要新的观察技术。” 西门子公司超声部主任Klaus Hambuchen说。

8F导管不久就可以在欧盟国家与Acuson Sequoia、Acuson CV70、和Acuson Cypress心血管系统配套使用。

Velocity Vector Ultrasound
 
Velocity vector imaging is a promising new tool for the assessment of myocardial mechanics and is a motion analysis method developed by cardiologists and physicists over the past three years. It provides more comprehensive cardiac contraction and motion data with the possibility to evaluate cardiac anatomy in patients with congestive heart failure, dyssynchrony, and other myocardial function disorders.

Velocity vector aiming is intended for use with any transducer for all cardiovascular aiming including pediatrics, adult, transesophageal (TEE), intracardiac echocardiography, vascular, and fetal applications.

Siemens Medical Solutions (Erlangen, Germany) introduced this new technology with the release of the Acuson Sequoia echocardiogram platforms, accompanied by the presentation of the Acuson AcuNav 8F ultrasound catheter at the annual congress of the European Society of Cardiology, held in Stockholm (Sweden) in September 2005.

The AcuNav 8F is 33% smaller in the cross-sectional region than the existing AcuNav 10F catheter and enables improved assessment in all patients, especially smaller patients, and for left heart applications in electrophysiologic and interventional cardiology. “The trend in cardiac procedures is toward less-invasive surgery, going from open surgery to keyhole access, and now to catheter-based procedures, which demand new visualization techniques,” stated Klaus Hambuchen, head of the ultrasound division at Siemens.

The 8F catheter will soon be available in the European Union countries for use with the Acuson Sequoia, the Acuson CV70, and the Acuson Cypress cardiovascular systems.
