  • Video Magnification Applied in Ultrasound

    Video magnification is a computational method increasing the subtle temporal motion in videos. This visualization method is proposed here for medical ultrasound images, as an alternative to standard vectors and color map illustrations. Small changes are amplified to be easily seen with a naked eye to render in a natural way subtle and fast displacements that are happening in tissue without obscuring any anatomical information. Video magnification could be a new tool for physicians to highlight new pathology indicators or for long-term disease monitoring; it could also be used for rapid qualitative inspection or educational purposes.
