Abstract
The present technology is generally directed to filtering systems and methods for suppression of reverberation artifacts in ultrasound images. In some embodiments, a method of obtaining a filtered ultrasound image includes taking a first ultrasound image of a target tissue using an applicator. At least a portion of the applicator is moved such that the reverberation artifact ultrasound path length changes relative to the first position of the applicator. A second ultrasound image of the target tissue is then taken. The first and second ultrasound images are synthesized using at least one filtering method. The filtering method attenuates or removes reverberation artifacts in the synthesized ultrasound image.
