First Claim
1. A system for real-time visualization of scene shift of an object in an ultrasound scan, comprising:
- means for developing a first ultrasound image;
means for determining a first border of the object in the first ultrasound image;
means for developing a second ultrasound image;
means for determining a second border of the object in the second ultrasound image;
means for forming an overlay of the first border on the second border; and

Abstract
A system and method for visualizing scene shift over successive ultrasound scan frames is disclosed. In one embodiment the invention is a system for real-time visualization of scene shift in an ultrasound scan, comprising an ultrasound receiver for developing a first ultrasound image and a second ultrasound image, border formation software for determining a first border corresponding to the first ultrasound image and a second border corresponding to the second ultrasound image, and image misalignment detection software for overlaying the first border on the second border to determine whether the first border aligns with the second border. Corresponding systems, methods and computer-readable media are also disclosed.
