A subset of the 2D imaging mode in which the 2D image is enhanced by
reducing speckle noise artifact at tissue margins and improving contrast
resolution by reducing artifacts and improving visualization of texture
patterns within the image.
A subset of the 2D imaging mode in which the 2D image is enhanced by
looking at a target from multiple angles and then merging or averaging the
scanned data together to improve overall image quality and, in parallel,
reducing noise and artifacts.
A pulsed wave Doppler technique used to detect myocardial motion.
The ratio of total acoustic power to the acoustic power required to raise tissue
temperature by 1°C under defined assumptions. See
Output, " for a more complete description of TI.
A thermal index for applications in which the ultrasound beam passes
through soft tissue and a focal region is in the immediate vicinity of bone.
A thermal index for applications in which the ultrasound beam passes
through bone near the beam entrance into the body.
A thermal index related to soft tissues.
Transmits at one frequency and receives at a higher harmonic frequency to
reduce noise and clutter and improve resolution.
A device that transforms one form of energy into another form of energy.
Ultrasound transducers contain piezoelectric elements, which when excited
electrically, emit acoustic energy. When the acoustic energy is transmitted
into the body, it travels until it encounters an interface, or change in tissue
properties. At the interface, an echo is formed that returns to the transducer,
where this acoustic energy is transformed into electrical energy, processed,
and displayed as anatomical information.
Displays a variation in Color Doppler flow imaging within a given sample.
Variance is mapped to the color green and is used to detect turbulence.
