A way to overcome ultrasound attenuation is time gain compensation (TGC), in which signal gain is increased as time passes from the emitted wave pulse. This correction makes equally echogenic tissues look the same even if they are located in different depths.

Key term(s)
  • time-gain compensation
  • time-gain control

Le gain étagé correspond à l'amplification de la captation par la sonde des ultrasons réfléchis sur des zones étagées, avec une intensité d'émission inchangée. Sur l'écran, cela se traduit par l'ajustement de la brillance de l'image sur une profondeur donnée.
