Systems and methods for automated ultrasound image recording based on quality scores
Systems and methods for automated recording of an ultrasound clip are based on quality scores of ultrasound images in a sequence of ultrasound image frames. An ultrasound imaging system includes a probe for capturing ultrasound images, an image buffer to store a sequence of image frames, a quality buffer to store a sequence of quality scores, and a computing subsystem that automatically records an ultrasound clip when the quality scores in the quality buffer corresponding to a set of contiguous image frames in the image buffer equal or exceed a first quality threshold and the set of contiguous image frames is at least a first predetermined size. Additionally, a smart capture feature automatically records an ultrasound clip including an alternate set of contiguous image frames having quality scores equaling or exceeding a second quality threshold that is less than the first quality threshold and meets a second predetermined size.
