Speed-of-sound imaging using diverging waves
Did you know?
WebThe rise of ultrafast ultrasound imaging - with plane or diverging waves - paved the way to new applications of ultrasound in biomedical applications. Though, propagation through complex layers (typically fat, muscle, and bone) hinder considerably the image quality, especially because of sound speed heterogeneities. WebFeb 1, 2024 · The maximum detectable velocity of high-frame-rate color flow Doppler ultrasound is limited by the imaging frame rate when using coherent compounding techniques. Traditionally, high quality ultrasonic images are produced at a high frame rate via coherent compounding of steered plane wave reconstructions. However, this …

WebNational Center for Biotechnology Information WebSpeed-of-sound (SoS) has been shown as a potential biomarker for breast cancer imaging, successfully differentiating malignant tumors from benign ones. SoS images can be reconstructed from time-of-flight measurements from ultrasound images acquired using conventional handheld ultrasound transducers.
WebApr 11, 2024 · ( a) Alternating plane and diverging waves with plane waves to provide highly correlated data and diverging waves to provide a wide acceptance angle for coherent combination. ( b) Diverging waves transmitted from each edge instead of the center to maximize the effective transmit aperture extent.
