Publication number: 20200245970Abstract: A method for prescriptively guiding an operator of an ultrasound imaging probe includes acquiring a sequence of image clips of a target organ utilizing an ultrasound imaging probe, determining a particular view of the target organ expressed by the acquired image clips and assessing a quality of each of the acquired image clips in respect to the particular view. On condition that the assessed quality falls below a pre-determined satisfactory quality for the particular view, a prescriptive movement of the probe is computed that has been pre-determined to produce quality improvement of a subsequently acquired image clip of the target organ for the particular view. Then, responsive to determining that the prescriptive movement has been computed a threshold number of times in connection with the sequence, the prescriptive movement is displayed concurrently with a display of subsequently acquired image clips of the target organ.Type: ApplicationFiled: January 31, 2019Publication date: August 6, 2020Inventors: Charles Cadieu, Ali Chaudhry, Sara Guttas, Ha Hong, Ching Hsieh, Kilian Koepsell, Nripesh Parajuli, Nicolas Poilvert
