Table 3 Examples of emerging technologies in the sector of ultrasound devices. The first column contains the keywords extracted with the contrast procedure explained in the text, plus the ultrasound filter; the second column lists the other relevant words that recur associated with them, reorganized according to syntactic or semantic similarity in order to facilitate interpretation; finally the third column provide the interpreted description of the technology
