From Siemens Medical Systems;
The new gold standard in echocardiography is defined by Native Tissue Harmonic Imaging (NTHI) and DELTA Differential Echo Amplification−two powerful technologies that were first introduced on Acuson's Sequoia™ echocardiography system. Now they have migrated to the Aspen™ Advanced system.

Specifications for this system will be available soon.

From Siemens Medical Systems;
We see a way to combine quality, versatility, and affordability in a slim, 20-inch wide, ergonomically designed ultrasound system. The new ACUSON CV70™ cardiovascular ultrasound system provides dedicated and complete cardiovascular capabilities in a powerful, all-digital ultrasound system offering exceptional image quality, Doppler sensitivity, color flow sensitivity and spatial resolution − everything you associate with the ACUSON family of cardiovascular products.

Specifications for this system will be available soon.

In physics, the absorbed dose is the ultrasonic power absorbed per unit of mass of an object, and is measured in watts per kilogram (W/kg). The absorption increases with ultrasound intensity and frequency.
The thermal index describes the potential for heating of the patient's tissue due to the application of energy.
