Key result
Novel ultrasonic-Doppler method accurately detects subtle aortic wall vibrations despite large heartbeat motion.
Why the study?
Accurate detection of small vibrations of the aortic wall near the heart is necessary for acoustical diagnosis of atherosclerosis but is difficult with previous ultrasonic methods due to large heartbeat motion.

Simulation-validated method may enable aortic vibration assessment for atherosclerosis; leaves open in vivo and clinical validation.
A new ultrasonic-Doppler-based method was developed and evaluated in simulations to accurately measure small vibrations of the aortic wall for diagnosing atherosclerosis.
Kawabe et al. (1993) conducted a letter in Atherosclerosis. New ultrasonic-Doppler-based method for measuring small vibrations was evaluated on Accuracy of measuring small vibrations of the aortic wall. A new ultrasonic-Doppler-based method was developed and evaluated in simulation experiments to accurately measure small vibrations of the aortic wall despite large amplitude motion from the heartbeat.
