Ultrasound imaging systems and methods for detecting object motion

Abstract

Ping-based imaging systems may be used for tracking motion of hard or soft objects within an imaged medium. Motion detection and motion tracking may be performed by defining fingerprint points and tracking the position of each fingerprint point based on the echoes of multiple transmitted pings.

Problems solved by technology

Scanline-based imaging systems also have inherent frame rate limitations, which create difficulties when attempting to image moving objects in 4D

[0008] Due to these and other factors, some of the limitations of existing 2D and 3D ultrasound imaging systems and methods include poor temporal and spatial resolution, imaging depth, speckle noise, poor lateral resolution, blurred tissue, and other such problem
