We have developed an automatic breathing level tracking method that tracks the changes in the patient's breathing level and an active breathing level control method that can control the patient's breathing pattern by applying external pressure to the patient's abdomen. The active breathing level control method can be used to control the patient's breathing level and reduce the scan time and also improve image quality when the tracking range of the automatic tracking method is controlled appropriately. It is therefore concluded that these methods can be very helpful in clinical WH MRCA studies.
