Abstract:
Ultrasound imaging devices, systems, and methods are provided. In one embodiment, a method of reducing ringdown artifacts in an ultrasound imaging system includes obtaining a plurality of frames of samples including tissue information and a ringdown component; determining a reference frame based on the plurality of frames to approximate the ringdown component; subtracting the reference frame from a current frame of the plurality of frames to produce a difference frame; selecting between the current frame and the difference frame to obtain a ringdown-reduced frame to represent the tissue information; and forming an ultrasound image from the ringdown-reduced frame. In one embodiment, an ultrasound image processing system including a processing unit configured to compute a difference frame based on a current frame and a reference frame; and select between the current frame and the difference frame to obtain a ringdown-reduced frame to represent the tissue information.
