Patent number: 11464490Abstract: A method for providing real-time feedback and semantic-rich guidance on ultrasound image quality is performed by a processor in an ultrasound system. The method includes receiving an ultrasound image and classifying the ultrasound image into one or more categories based on image features. The classifying creates a classified image. The method also includes determining whether the classified image provides an acceptable representation of a target organ. In response to determining that the classified image does not provide an acceptable representation of the target organ, the method includes selecting operator guidance corresponding to the one or more category; presenting via a display and/or audible sound, the selected operator guidance; and receiving additional ultrasound images. The method further includes calculating a result based on the classified image in response to determining that the classified image provides an acceptable representation of the target organ.Type: GrantFiled: November 13, 2018Date of Patent: October 11, 2022Assignee: Verathon Inc.Inventors: Si Luo, Dave Scott
