Tissue Motion Quantification (TMQ) and Advanced Tissue Motion Quantification (TMQA) plug-ins provide you with a new method based on 2D speckle tracking technology for assessing global, regional and local cardiac function at rest and effort. These plug-ins offer a suite of measurements and parametric displays to analyze transmyocardial mechanics without Tissue Doppler imaging angle dependency limitations. |
Using the 17-segment ASE left ventricular model, TMQ and TMQA provide additional information for many clinical applications such as ventricular wall motion and mechanical synchrony assessments.
The excellent 2D image quality provided by PureWave crystal technology allows robust multicycle tracking of ventricular endocardial, epicardial and transmural layers. Using an extension of the intuitive 2DQ user interface, TMQ and TMQA, you can place and observe the tracking points and edit the individual tracking points at anytime. TMQ computes multidirectional myocardial speed and strain while TMQA offers you more advanced parameters, such as wall thickening, global and regional left ventricular rotation, and multilayer myocardial rotation gradients.
TMQA offers the unique "free strain" feature, providing you with the ability to assess user defined local velocities, displacement and deformation using unlimited directional chords display technique. It’s an easy, quick and accurate strain method.
Additionally, TMQ and TMQA include TMAD. In three clicks you can assess cardiac cavity global functions by measuring and displaying the valves’ annular elevation motion over time.
Like other QLAB plug-ins, TMQ and TMQA can export automatically detected and manually edited LV volumes, LV ejection fraction, strain peak and time to peak values to iE33 and Xcelera reports, or create a comprehensive report on the QLAB PC workstation.
