Claim 5:
6. An ultrasound imaging system, comprising:
an interface coupled to at least one of a transducer array and a beamformer, the interface to receive a plurality of image data frames representative of a subject's body including at least a portion of a lung across a time period, each image data frame of the plurality of image data frames including a plurality of pixel values representing pixel intensities of an image of the subject's body;
a processor in communication with the interface and configured to:
identify a subset of data from the plurality of image data frames by selecting one or more pixel values from each image data frame of the plurality of image data frames corresponding to a same sub-portion of the at least a portion of the lung;
determine an intensity metric for each image data frame from the subset of data; and
determine a dynamic air bronchogram (AB) condition of the subject's body based on a temporal variation across the subset of data by comparing a maximum of the intensity metrics across the time period to a minimum of the intensity metrics across the time period, wherein the dynamic AB condition is determined based on a calculated ratio between a maximum of the intensity metrics and a minimum of the intensity metrics.
