SYSTEMS AND METHODS FOR MULTI-RESOLUTION DISCRIMINANT ANALYSIS FOR ULTRASOUND IMAGING

摘要

An ultrasound system includes an ultrasound transducer, a processing circuit, and an output device. The ultrasound transducer detects ultrasound information and outputs the ultrasound information as ultrasound data samples. The processing circuit receives ultrasound data samples from the ultrasound transducer, calculates a plurality of first spectra for a first subset of the received ultrasound data samples, generates a threshold based on the plurality of first spectra, categorizes first spectra greater than the threshold as signal data, otherwise as noise data, processes the signal data using a first signal processing parameter and the noise data using a second signal processing parameter different from the first signal processing parameter, and combines the processed signal data and noise data into an ultrasound output. The output device is configured to output the ultrasound output as at least one of an ultrasound image or ultrasound audio.
