Abstract
Methods and apparatuses for processing ultrasound signals. An approximation signal is generated to approximate an undesirable component of an input signal. The input signal may represent an ultrasound (e.g., Doppler) echo from a body. The approximation signal is used to remove the undesirable component from the input signal, leaving an output signal, which may be further processed by an ultrasound measurement and/or imaging system.
