Needle segmentation concept. A voice coil actuator (vibrator) vibrates the needle, resulting in a Doppler response around the needle cross section in a 2-D ultrasound image. The needle is segmented by localizing the Doppler response across the sweep of a mechanical 3-D ultrasound transducer, and fitting a curve through the resulting points.
