Speckle tracking in Ultrasounds images

In collaboration with
Internal Medicine Unit of Mater Domini General Hospital (Catanzaro)

Motion of soft tissues is often quantified through wide used ultrasound images, this modality is non-invasive, non-ionizing and have good time resolution. Ultrasound images show a characteristic type of noise called “speckles”, due to random interference patterns and natural acoustic reflections. This kind of noise show a certain type of stability through consecutive frames. Identification and tracking of groups of stable speckle allow to quantify displacement of soft tissues.
This approach is widely used in ecocardiography in order to estimate atrial or ventricular deformations. We applied this kind of analysis to estimate intima media/adventitia longitudinal displacement in healthy and in subject with stent implanted.
