Siemens debuts tissue harmonic imaging

Siemens Ultrasound of Issaquah, WA, has become the latest ultrasound vendor to add tissue harmonic imaging capabilities to its product line. The firm's version, called Ensemble Tissue Harmonic Imaging, will be offered on its premium Sonoline Elegra ultrasound scanners.

The new release allows Elegra users to isolate harmonic signal data without the use of contrast agents, according to the firm. Ensemble supports high-frequency imaging and can provide demonstration of breast lesions and superficial images. The system also shows promise in scanning difficult-to-image patients.

Ensemble eliminates the impact of signal artifacts common during high-frequency scanning with its pulse-inversion technology, which isolates harmonic imaging signals, according to Siemens. Combining the harmonic imaging signals with fundamental signal data allows Elegra to yield improvements in tissue contrast and spatial resolution in nearly all radiological applications, the company believes.
