From: High-speed, high-frequency ultrasound, in utero vector-flow imaging of mouse embryos
One frame of a 245-ms duration, high-speed acquisition from an E16.5 embryo in the area of the heart (H) and umbilical cord (UC) showing (a) B-mode image, (b) non-stationary flow speckle, (c) Doppler spectrogram in the region of the UC using the averaged slow-time data from the boxed region in (a), d) color-flow Doppler image. The yellow line in (c) 76 ms after the start indicates the time point of the images. The full image sequence is available as Movie 3.
