Reducing noise in phased-array signals from receivers located at different locations

A computerized method to reduce noise in phased-array signals from a set of transducers of an ultrasound apparatus, the transducers being at different locations, wherein the method comprises:

• receiving time-series from the transducers, the time-series forming phased-array signals;
• ordering the time-series based on the different locations of the transducers and obtaining, from the ordered time-series, spatially phased series, wherein each of the spatially phased series obtained comprises a series of signal values that are spatially phased;
• and
• identifying a noise component in each of the spatially phased series obtained and removing the identified noise component from said each of the spatially phased series obtained to obtain denoised, spatially phased series;
• and
• passing the denoised, spatially phased series for further processing to reconstruct an estimate of a true signal according to each of the denoised, spatially phased series obtained, wherein:
• said set of radiofrequency coils are arranged in an array;
• said radiofrequency coils introduce noise;
• and
• said ordering the time-series is performed based on the different locations of the radiofrequency coils.
