SYSTEM AND METHOD FOR IDENTIFYING A DOPPLER SIGNAL FROM A TARGET BLOOD VESSEL

摘要

The invention provides a system and a method for identifying a Doppler signal from a target blood vessel. The system comprises: a receiving unit (21) for receiving a Doppler signal, an extracting unit (22) for extracting a signal envelope from the Doppler signal, a determining unit (23) for determining that the Doppler signal originates from the target blood vessel according to geometric parameters of the signal envelope, and a generating unit (24) for generating an indication indicating to acquire a status of the target blood vessel.
