A depth on the display that corresponds to the skin/transducer
interface.
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
"Safety, " 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.
