Abstract

A method of determining a status of ultrasound coupling medium for performing an ultrasound scan for providing an ultrasound image including plural scanlines (N_l) is disclosed. In an embodiment, the method includes operating an ultrasound device to capture an image frame including plural scanlines (N_l), each scanline having an associated sample set (s) of intensity values; processing a subset of the associated sample set (s) of values for each scanline to determine a first summation for each scanline; processing plural sets of corresponding intensity values from each of plural scanlines located within a range of a respective scanline to determine a set of difference values for each respective scanline; processing each set of difference values to determine a second summation for each scanline; and generating a status for the ultrasound coupling medium according to a relationship between each of the first summations and each of the associated second summations.
