  • Publication number: 20210106284
    Abstract: A method for clip selection includes receiving through an interface to a medical imaging device, a selection of a diagnostic procedure and a target portion of a mammalian body. Thereafter, the device acquires video clip imagery of the target portion and stores the video clip imagery in an image store. Each video clip of the video clip imagery is then image processed to determine a view and a quality of each video clip and a rule is retrieved from a rules base corresponding to the selected diagnostic procedure and target portion. In this regard, the rule specifies a requisite view and quality of the video clip imagery. Finally, the retrieved rule is applied to the video clip imagery as a filter to produce a subset of video clip imagery satisfying the specified requisite view and quality and the subset of video clip imagery is stored in the image store.

  • Publication number: 20200245970
    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.

  • Publication number: 20200245976
    Abstract: In a method, system and computer program product for retrospective image clip saving for ultrasound imagery, the method includes first repeatedly acquiring different ultrasound image clips of a single view of a target feature through an ultrasound imaging probe of an ultrasound imaging system. Thereafter, each of the acquired different ultrasound image clips may be stored in a buffer of the ultrasound imaging system and a value assigned to each of the image clips according to a measured characteristic. 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.

In an embodiment of the invention, a method for video clip quality determination in medical imaging includes first retrieving from a data store into memory of a host computer, video clip imagery of a target organ. Then, a quality value assigned to the video clip imagery may be identified in connection with the retrieved video clip imagery. A measurement of the target organ is computed based upon the retrieved video clip imagery. Finally, a confidence in respect to the computed measurement is determined based upon the identified quality value and the confidence determination displayed in a user interface provided by the host computer.
