This is an example of carotid plaque in a difficult-to-image patient. With conventional imaging, the internal carotid artery plaque could not be identified. With SonoCT Real-time Compound Imaging, the soft plaque as well as the residual lumen is clearly defined.

SonoCT imaging is a unique approach to acquiring and processing ultrasound data and was developed to overcome the inherent artifacts of conventional ultrasound, which compromise image quality. SonoCT Real-time Compound Imaging obtains multiple coplanar, tomographic images from different viewing angles, then combines them into a single compound image at real-time frame rates. SonoCT imaging enables clinicians to acquire up to nine times more information than they can with the orthogonal beams used in conventional ultrasound, without any unusual manipulation of the scanhead and without sacrificing frame rates.

The ability of SonoCT imaging to improve image quality primarily depends upon suppressing image artifacts. By scanning from different angles to produce different artifact patterns, then averaging these independent frames, artifacts such as speckle, clutter, noise, glint, dropout and refractive shadows are suppressed and real structures reinforced. The resulting image is a more realistic representation of actual tissue.
