Ultrasound system and method of forming ultrasound image

An ultrasound system comprising:

• a probe operable 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 operable to generate volume data based on the ultrasound echo signals;
• a display unit to display a 3-dimensional ultrasound image constructed based on the volume data;
• and
• a user input unit 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 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 a 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.
