Systems and methods for ultrasound screening

An ultrasound system, the system comprising:

• an ultrasound transducer array, wherein the ultrasound transducer array comprises a plurality of transducer elements, adapted to conform with a subject's body and wherein at least two ultrasound transducer elements of the plurality of transducer elements are adapted to acquire a plurality of ultrasound signals from a region of interest at different orientations relative to said region of interest;
• and
• a processor adapted to receive ultrasound signals acquired by the ultrasound transducer array, wherein the processor is adapted to:
• partition the plurality of ultrasound signals according to a signal depth;
• for each ultrasound signal partition, calculate a Doppler power;
• for each ultrasound signal, identify a depth of a fetal heartbeat based on the Doppler power of each ultrasound signal partition;
• and
• identify a fetal heart region based on the identified fetal heartbeat and a location of the at least two ultrasound transducers,
• wherein the identifying of the depth of the fetal heartbeat comprises comparing the Doppler power to a threshold power, and
• wherein the identifying of the depth of the fetal heartbeat further comprises clustering the Doppler power values above the threshold power.
