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;
Four technology cornerstones are the foundation of the Acuson Sequoia™ platform's unrivaled clinical performance. They work together to deliver a new level of diagnostic confidence in echocardiography.

Specifications for this system will be available soon.

(TTE) Transthoracic echocardiography is a common type of cardiac ultrasound and is used to evaluate the size and function of the heart.

Indications:
TTE requires no sedation or special patient preparation. After the application of ECG electrodes and ultrasound couplant, the probe is maneuvered over the chest in the area adjacent to the breast bone and under the left breast, to provide the different views of the heart. Usually the images will be obtained lying relaxed on the left side. Other views can be sampled lying on the back with the knees bent, or sitting in an upright position.

From Siemens Medical Systems;
'Conventional ultrasound systems are unable to compensate for the unique acoustic signature of individual patients. But there is nothing conventional about the new ACUSON Sequoia™ C512 echocardiography system with Sequoia™ matched response technology.'

Bicycle stress echocardiography can be used instead of treadmill. Bicycle exercise is particularly useful for patients with valvular heart disease or for evaluated pulmonary artery pressures. It is also used as a substitute for treadmill exercise testing when the heart performance at each stage of exercise needs to be assessed and the patient is capable of bicycle exercise. Bicycle stress echocardiography has no additional risk compared to routine exercise.
