    摘要： A medical diagnostic ultrasonic imaging system acquires image data for at least two frames at each of multiple positions, each frame identified with a respective phase of a physiological cycle. A multiphase 3-D or extended field of view data set is constructed from the image data. Then a plurality of images are generated from the multiphase data set. Each image is associated with a respective phase of the physiological cycle, and these images are displayed in sequence to a user. The acquired sequence of image frames is synchronized by adding frames to the sequence in portions of the sequence characterized by a low number of image frames per period of the physiological cycle, and by removing image frames from portions of the sequence characterized by an excessive number of frames per period of the physiological cycle.

    摘要： A system for editing a 3-D medical diagnostic ultrasound image dataset displays both a 3-D reconstruction of the dataset and an editing object. A user moves the editing object relative to the 3-D reconstruction with a six degrees of freedom input device that allows the user to control both the position and the orientation of the editing object. The 3-D reconstruction and the associated 3-D dataset are edited to reduce opacity of a portion of a 3-D reconstruction on a selected side of the editing object. The disclosed editing system is fast, efficient and intuitive, and it allows the user to designate the portions of the 3-D dataset to be removed simply and reliably.

    摘要： A method and system for generating three-dimensional representations using opacity modulation are provided. The opacity level associated with each datum in a 3D volume data set is controlled as a function of at least one Doppler parameter, such as variance. Areas of high variance are assigned a higher level of opacity than areas of low variance. For a Doppler velocity image, velocities associated with high variance are displayed more opaquely than velocities associated with low variance, thereby emphasizing the more opaque regions. The more transparent velocities (i.e., those associated with low variance) still contribute to the image and are displayed. Other Doppler parameters may be used for the image, such as energy, tissue motion or variance. Furthermore, other Doppler parameters may be used to control the opacity, such as velocity, energy or tissue motion.

    摘要： A method for making Doppler ultrasound measurements utilizes an ultrasound probe having two transducer arrays oriented at right angles to one another and spaced apart from one another. The first array is used to measure multiple apparent Doppler parameters such as velocity at respective regions within a cross section of a structure such as a blood vessel. The second array is used to measure second apparent Doppler parameters at one of these regions. The first and second apparent Doppler parameters for the same point are used to correct the first apparent Doppler parameters to more nearly equal true velocity or energy.

    摘要： In some illustrative embodiments, an ultrasonic transducer drive includes a signal generator for producing an outgoing signal and a transducer for converting the outgoing signal to outgoing ultrasound. The transducer may also convert at least a portion of ultrasound reflected by an object to an incoming signal. The transducer may have a transmit side connected conductably to the signal generator during at least a first predetermined period of time and a receive side connected conductably to a signal receiver during at least a second predetermined period of time. A shunt may be connectable between the receive side and a reference potential. The signal generator may generate the outgoing signal during at least substantially the first predetermined period of time while the shunt connects the receive side to the reference potential. The signal receiver may receive the incoming signal during substantially the second predetermined period of time while the shunt is substantially open.
