1. A method of processing an ultrasound signal, the method comprising:
processing the ultrasound signal into a waveform, the ultrasound signal corresponding to blood flow within a blood vessel of a subject;
identifying three morphological variables of the waveform processed from the ultrasound signal, wherein the three morphological variables comprise:
a first variable comprising an absolute peak onset of the waveform;
a second variable comprising a length of a canopy of the waveform; and
a third variable comprising a number of auxiliary peaks of the waveform and/or prominence of the auxiliary peaks of the waveform;
mapping the three morphological variables to a point within a three-dimensional space;
determining, based on the point in the three-dimensional space, a probability that the morphological variables of the waveform corresponds to a category associated with a blood vessel condition;
determining that the waveform is indicative of belonging to the category; and
displaying the probability that the waveform belongs to the category.
