Patent ID: 8721547

Claim:
An ultrasound system comprising: a probe configured to transmit ultrasound signals to a target object containing a periodically moving object and to receive ultrasound echo signals reflected from the target object; a processor configured to generate volume data based on the ultrasound echo signals; a display configured to display a 3-dimensional ultrasound image constructed based on the volume data; and a user input configured to receive user inputs regarding reference image setup information and M-mode line setup information associated with the 3-dimensional ultrasound image, wherein the processor is further configured to generate a reference image representing a plane cut through the 3-dimensional ultrasound image using the volume data, the cut plane designated based on the reference image setup information and to generate an M-mode line on the reference image which is designated based on the M-mode line setup information, and M-mode images are generated and displayed based on the M-mode line on the reference image which is designated using the 3-dimensional ultrasound image.
