Cardiac imaging with high frame rate contrast enhanced ultrasound: In-vivo demonstration
2016 IEEE International Ultrasonics Symposium (IUS), 2016•ieeexplore.ieee.org
This work presents the first in-vivo High-frame rate Contrast Enhanced Ultrasound (HFR
CEUS) for cardiac application. The in-vivo acquisition has been made on a sheep. A
coherent compounding of diverging waves combined with Pulse Inversion (PI) transmission
allow a frame rate of 250 frame per seconds which is 8 times faster than standard CEUS
acquisition in cardiac application. The proposed method improves the image contrast
compared to the CEUS and allows a better tracking of fast movement of the heart.
