Description

ABSTRACT:
The disclosed ultrasound system processes ultrasound signals having centroid frequencies that decrease as a function of time. The system includes transducers for receiving the ultrasound signals and generating electrical signals representative thereof. The system further includes data samplers for sampling the electrical signals with a sampling frequency. A controller controls the sampling frequency so that it decreases according to a function of time and the centroid frequency.
