Reverberation Noise Reduction | Stanford Ultrasound Imaging ...
Diffuse reverberation is ultrasound image noise caused by multiple reflections of the transmitted pulse before returning to the transducer, which degrades image quality and impedes the estimation of displacement or flow in techniques such as elastography and Doppler imaging.

Reverberation artifact. Reverberations can also occur if sound waves returning to the transducer are reflected back to the tissue. Reverberations are common when examining lung tissue; the double-layered pleura produce reverberations, which are referred to as A-lines .

Reverberation - Wikipedia
Reverberation (commonly shortened to reverb), in acoustics, is a persistence of sound after it is produced. [1] Reverberation is created when a sound or signal is reflected. This causes numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and ...

What is Reverb, and How Is It Measured? | Acoustical Surfaces
Measuring reverb using a sound level meter can be a useful tool for optimizing the acoustic environment of a recording studio, performance venue, or other space to achieve the desired sound quality. It can also be used to diagnose and troubleshoot acoustic problems in a room, such as excessive echo or resonance .

Axial direction artifacts are located below the image of the real structure and consist of simple and complex reverberations, mirror image artifacts, and acoustic shadowing/enhancement. The reverberation artifact violates the assumption that an echo …
Acoustics Chapter One: Reverb - Indiana University Bloomington
Reverberation or reverb is the prolongation of sound waves via reflection and refraction. While it may occur continuously during the course of a sonic event, it is most noticeable and measurable after the source impulse has ended.
