Siemens Medical Solutions this week introduced new technology for its Acuson Sequoia C512 and C256 echocardiography systems, including Native TEQ dynamic ultrasound technology and a new 8V3 transducer, at the American Heart Association (AHA) Scientific Sessions in New Orleans, La.

Native TEQ technology enables the ultrasound system's computer to read the signals that are returning from the individual patient, and then automatically adjust the parameters while the operator is scanning. There are no gain or depth-gain-compensation (DGC) control adjustments needed while scanning. The computer is programmed to perform advanced real-time motion analysis in addition to accurately detecting and differentiating noise and artifacts from soft tissue, Siemens said

Designed for pediatric and fetal echo exams, the 8V3 transducer is based on the company's proprietary Hanafy lens technology, providing continuous focusing and image uniformity, broader bandwidth and differentiation of near field structures with higher resolution, Siemens said.

Siemens demonstrated new advancements on the Acuson CV70 cardiovascular system, such as fourSight transesophageal (TEE) view for integrated three-dimensional (3D) TEE imaging, and the new P9-4 transducer for pediatric cardiac imaging. Through advanced technology migration from the Sequoia system, 3D TEE imaging is now available with the CV70, enabling easier access to 3D/4D images through simple acquisition, review, manipulation and dynamic display capabilities of gated 3D datasets using the V5Ms TEE transducer. For TEE imaging, 3D surface or multiplanar reconstruction can provide physicians a more detailed, anatomical display of the heart and clinical disease processes, and with the V5Ms TEE transducer, physicians will have easier access to high quality 3D images, Siemens said.

With the addition of the new P9-4 transducer for pediatric imaging, the CV70 cardiovascular system now supports extensive transducer capabilities, enabling clinicians to conduct a wide range of cardiovascular studies including stress echo, adult, pediatric and fetal echocardiograms, and epiaortic imaging, Siemens said.

The company also displayed its new Acuson AcuNav 8F ultrasound catheter for visualization of vascular and cardiac anatomy and physiology, measurement of blood flow, and visualization of other devices throughout the entire heart. The AcuNav 8F catheter is 33 percent smaller in the cross sectional area than the existing AcuNav 10F catheter, enabling improved access during closure of atrial septal defects (ASD) on smaller patients, and left heart applications for both interventional cardiology and electrophysiology.
