Simulated ultrasound data from carotid arteryThe RF data was obtained from simulating the flow in the carotid artery by using the Field II program and the data from page 80 in the book. The Womersley-Evans method for pulsed flow described on page 75-79 was used for finding the pulsatile velocity. The RF data was then demodulated and sampled to obtain the complex audio data. The data for the simulation are given below:
The audio data can be obtained from the web-server from the directory: The file is called car_audio.mat and the Matlab variable audio contains the complex audio data. |
