Color flow imaging Color flow Doppler ultrasound produces a color-coded map of Doppler shifts superimposed onto a B-mode ultrasound image (Color Flow Maps). Although color flow imaging uses pulsed wave ultrasound, its processing differs from that used to provide the Doppler sonogram. Color flow imaging may have to produce several thousand color ...

flow dynamics in an artery (e.g., ultrasound color flow imaging of the carotid artery) is an example of a non-invasive sensor. Contact/Remote: A strain gauge sensor attached to a muscle fiber can record deformations and forces in the muscle. An MRI or ultrasound imaging system can measure internal deformations and forces without
