The ratio of total acoustic power to the acoustic power required to raise
tissue temperature by 1°C under defined assumptions. See
"Acoustic 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.
