1. A processing system configured to generate M-mode data by processing a sequence of ultrasound images, the processing system being configured to:
obtain the sequence of ultrasound images, each ultrasound image containing a representation of a portion of a fetus, including at least the heart of the fetus;
identify, in the sequence of images, a region of interest that contains a representation of the heart of the fetus in each ultrasound image, wherein the step of identifying the region of interest comprises automatically detecting a first region of interest that contains a representation of the fetus in each ultrasound image, and automatically identifying, inside the first region of interest, a second region of interest that contains the representation of the heart of the fetus;
position a plurality of M-mode lines with respect to the sequence of ultrasound images, based on the identified region of interest;
for each of the plurality of M-mode lines:
generate M-mode data for the M-mode line;
determine a quality measure of the M-mode line by processing the generated M-mode data, rank the plurality of M-mode lines based on the determined quality measure of each M-mode line, and control a user interface to display a visual representation of rankings of the plurality of M-mode lines.
