New Ultrasound Technology Automatically Improves Image Quality

The Native TEQ (Tissue Equalization Technology/ Tissue Homogenization) technology developed by Siemens Medical Solutions enables automatic correction of the system parameters for optimal diagnostics. Therefore, the most frequently occurring erroneous settings can be avoided. This improves image quality and increases safety of diagnosis for most ultrasound applications. At the same time, the examination time is greatly reduced.

With Native TEQ tissue inhomogeneities, that would lead to irregular total gain settings, can be balanced. Gain alignment and automatic adaptation of the axial and lateral gain are performed by the ultrasound system during the ongoing patient examination. The scanning process is performed without the use of the keyboard. The processor accurately detects not only organs, but also differentiates noise components, compensates artifacts from soft tissue and performs a continuous motion analysis in real time. The image gain is automatically optimized in the axial and lateral direction as soon as the transducer touches the patient or is guided to a new acoustic window.

The Native TEQ ultrasound technology is based on two automated synergetic processes. Firstly, there is a monitoring function that checks the image in real time for changes in the finest of tissue and on the basis of the user interface. Secondly, it includes an optimization function that is immediately enabled in response to changes in the image plane. This technique automatically adapts the parameters during the scanning process so that all acquired images are improved in real time. The Native TEQ ultrasound technology optimizes system performance by automatically modifying patient-specific data prior to image generation.

During routine operation, the use of native TEQ ultrasound technology affects the course of the examination. Under space conditions with a low operating range or rather during bedside examinations, the physician no longer needs to be present directly at the system or have full access to the keyboard. As soon as the native TEQ is switched on and the ultrasound user positions the transducer in the appropriate measurement field at the patient, the scan can be completed without additional keyboard operation. This increases the physician’s concentration on the patient and the respective clinical question. Another positive aspect is the reduced examination time.

By using this unique technique, routine as well as inexperienced users can generate high-quality images in a highly efficient manner. Siemens uses the Native TEQ technology with both the Acuson Sequoia and Sonoline Antares “premium edition” ultrasound systems.
