This is the type of spilt-screen display you might see during an ultrasound, or if the technician prints a copy of the ultrasound for you. This ultrasound shows both the left arm (seen in the left side of the display), and the lower extremities (seen in the right side of the display). The white areas of the arm or legs is developing bone.
