Filed:

Jan 21, 2000

Appl. No.:

09/489575

Inventors:

Zoran Banjanin - Newcastle WA

Assignee:

Siemens Medical Solutions USA, Inc. - Iselin NJ

International Classification:

A61B 800

US Classification:

600453, 600441, 600455

Abstract:

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.

International Classification:

A61B008/14

US Classification:

600/459000

Abstract:

Methods and systems for obtaining ultrasound and sensing other patient charactristics are provided from summary. One or more sensors are provided in a same transducer probe as an array of elements. For example, sensors are formed on a same semiconductor substrate, such as a silicon substrate, as microelectromechanical devices or a capacitive membrane ultrasonic transducer (CMUT). As another example, a sensor is provided separate from or attached to transducer materials. Possible sensors include temperature, pressure, microphone, chemical and/or other sensors.

International Classification:

A61B008/00
A61B008/06

US Classification:

600437000, 600459000

Abstract:

A system and method for cooling an entirely or partially immersed mechanical or other type of transducer array is disclosed. Motion/flow of the immersion fluid is induced either by motion of the mechanical transducer itself, where the transducer is of the mechanically movable type, or by a separate motion-inducing mechanism located in or coupled with the fluid-filled, or partially filled, array housing. The resultant fluid flow/motion increases, i.e. more efficiently utilizes, the thermal carrying capacity of the immersion fluid by more uniformly distributing the thermal energy convected from the transducer array throughout the fluid volume. This results in an improved ability to cool the transducer array. The disclosed cooling system and method may be used in such a way so as to not substantially inhibit operation of the transducer array.

US Classification:

367103

Abstract:

In accordance with the principles of the present invention, advantage is taken by the inventors of the fact that the speed of operation of the digital hardware in a digital beamformer can be reduced by providing, for example, multiple phases of the data signals and then processing the multi-phase data in N parallel summing paths. An interpolation-decimation filter receives the multi-phase data from the N parallel summing paths and provides at its output a signal having a reduced data rate (1/N). In accordance with this technique, the speed of operation of the individual digital circuits for forming the required beamforming delays is not increased as compared to conventional post-beamforming interpolation schemes, so that hereby the effective data rate is increased by a factor N and results in a decrease of the delay quantization error by a factor N. In accordance with the principles of the invention, the interpolation-decimation filter is incorporated into the beamformer at a most advantageous place. That is, it is incorporated into the beamformer processing after partial beamforming of a group of receive channels and before formation of the final beam.
