摘要： A method for automatically placing a range gate over a moving blood vessel during ultrasound imaging. Doppler data received from a number of depths in the tissue is analyzed in order to calculate the average velocity of the tissue at each depth. A search is performed in the average velocities to select a maximum velocity. The maximum velocity is associated with a blood vessel and a range gate is placed at a depth corresponding to the maximum velocity. In a presently preferred embodiment of the invention, the average velocity is calculated by performing a first lag autocorrelation of the echo data received from each depth in response to a series of Doppler pulses.

摘要： The embodiments of the tracking device for the ultrasound imaging diagnostic apparatus include a predetermined combination of an ultrasound probe, an operator and a patient to be tracked, a space measuring device for measuring at least distance and angle of the probe based upon emitted electromagnetic radiation that is emitted towards the probe and reflected electromagnetic radiation that is reflected from the probe; and a processing device connected to the space measuring device for determining a change in distance and angle of the probe in space based upon on the emitted electromagnetic radiation and the reflected electromagnetic radiation. The space measuring device is used to track movement in a combination of a probe, a patient and an operator.

摘要： An improved technique for providing persistence to velocity signals obtained by an ultrasound imaging system is disclosed. The velocity signals with appropriate persistence are then used to form an image on a display device so as to accurately depict fluid flow. The persistence technique intelligently decides whether or not to provide persistence to the velocity signals. In making these persistence determinations, the persistence technique not only avoids distorting the velocity values with corrupt signals, but also preserves directional flow information. The persistence technique can also make use of various thresholds to reduce errors (e.g., flash artifacts or random noise) as well as persistence of such errors.
