WebJan 7, 2024 · Imaging techniques using sound waves have been a popular application since the dawn of the sonar technique. Though B-mode is one of the most used sonar-based methods (Schueler et al. 1984 ), this does not reach its potential as there is more information in received sound waves than what B-mode can offer. 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 …
