Normal CCA and ICA Images. A. This image was supplied to the UWURC on multiformat transparent film and scanned into the electronic image. Numbers in the red and yellow boxes have been enhanced for easier reading. B. The Doppler cursor is not aligned with the artery axis; the Doppler angle is 36°. A new velocity scale has been added in red along the right edge of the spectral waveform showing the results of the Doppler equation for a 36°angle.
