A save-best-clip mode of the ultrasound imaging system is then activated and, in response to the activation, each of the acquired different ultrasound image clips are compared in the buffer based upon respective measured characteristics, at least one of the clips demonstrating an optimal value for the measured characteristic is identified and the identified clip or clips saved in memory of the ultrasound imaging system in correspondence with the single view.

Abstract: 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.
