TEQ™ Ultrasound Technology
• TEQ ultrasound technology for 2D is a sophisticated signal-processing technology that automatically equalizes tissue gain and
brightness in two dimensions providing consistent, reproducible image quality in 2D
and M-mode at the push of a button
• TEQ ultrasound technology for spectral Doppler adapts to individual patient hemodynamics and instantly optimizes for PW and CW Doppler information, saving time and maximizing workflow- Automatically optimizes scale, baseline,
gain and dynamic range at the push of a button
• Pre-processing technology applied to RF echo data before image is formed
• Affords increased productivity and reduced inter-operator variability
• Overcomes limitations of conventional DGC adjustments for non-uniform tissue structures
• Assures optimal gain settings under suboptimal ambient lighting conditions for
stored images
• Assists in image brightness settings during contrast agent imaging studies
• Frees operator to focus on imaging – not on image quality adjustments
• Available on all transducers
