The spatial resolution of a US system is limited by the diffraction limit to length scales of approximately half of the wavelength of the transmitted beam; two or more points’ reflectors that are spaced more closely than this limit cannot be distinguished. For the real-time US visualisation and enhancement based on super-resolution, it is fundamental to address the US image resolution that is affected by the required frequency of the video, since some anatomical districts (e.g., cardiac) need a high acquisition frequency to accurately acquire the behaviour of anatomical features that quickly change over time.
