摘要： An ultrasound system is provided comprising an ultrasound probe having a 2D matrix of transducer elements transmitting a continuous wave (CW) Doppler transmit signal into an object of interest. The CW transmit signal includes a dither signal component and the probe receives ultrasound echo signals from the object in response to the CW transmit signal. The probe generates an analog CW receive signal based on the ultrasound echo signals. An analog to digital (A/D) converter converts the analog CW receive signal to a digital CW receive signal at a predetermined sampling frequency and a processor processes the digital CW receive signal in connection with CW Doppler imaging.

摘要： Method and apparatus for generating a multidimensional map of blood velocities in the circulatory system of living species, using the Doppler effect of backscattered ultrasound from the blood, with real time presentation on a display device, with the ability to select small sample volumes in the flow map where the information can be presented as a function of time together with the moving multidimensional map in real time. There is transmitted a pulsed ultrasonic beam which is swept in two or more dimensions through the region of the biological structure which is to be investigated. The backscattered ultrasonic signal is sampled in a number of depth volumes along each beam direction of the transmitted ultrasonic pulses. For each depth and beam direction there is determined a velocity parameter of the blood flow by means of the Doppler principle, and the velocity parameters from the whole region investigated are read into an image memory. Therefrom they are read out repeatedly for coded presentation on the display screen. By synthesizing on the basis of the backscattered signal from one or more selected sample volumes in the region investigated, there is generated an estimate signal to substitute the missing Doppler signal in these sample volumes while there is measured in other directions, for determining the frequency spectrum of the signal or a frequency parameter thereof, for example maximum frequency, which is simultaneously displayed as a function of time. The main use of the invention is for medical diagnosis, in particular in hospitals.

摘要： Method and apparatus for ultrasonic blood flow velocity measurement based upon the doppler principle (doppler measurement), combined with simultaneous echo amplitude imaging by employing ultrasonic pulses (echo imaging). The method is used for investigation of living biological structures, in particular during movement, for example a heart function. The main application will be in hospitals and the like. The doppler measurement and the echo imaging is effected sequentially with so short intervals that the echo imaging is updated with a sufficiently high rate for obtaining an acceptable picture quality, with the doppler measurement occupying a substantial portion of the time. The information is presented in real time on a display screen. A control unit synchronizes the doppler measurement and the echo imaging, and there is incorporated one or more transducers in the equipment. The doppler measurement is interrupted during intervals which constitute a not unimportant portion of the time, for carrying out a complete or a partly sweeping of the ultrasonic beam over the image field. There is formed an estimate of the doppler signal and the estimate replaces the directly measured doppler signal either all the time or during portions of the time, for example during the interruption interval.
