Abstract
Ultrasound systems and methods provide a workflow to automatically identify a fetal heartbeat. A region of interest (ROI) is identified in an ultrasound image and an ROI icon is positioned around or over a fetal pole and/or fetal heart. The ultrasound system produces spatially different M-mode lines associated with the ROI icon. The ultrasound system can identify a fetal heartbeat and estimate the fetal heart rate from echo signals received from echo signals associated with at least one of the spatially different M-mode lines. The echo signals for the M-mode lines can also be ranked according to the likely presence of a fetal heartbeat in the echo data.
