摘要： A medical diagnostic ultrasound imaging system aligns substantially co-planar two-dimensional images to form an extended field of view using improved compounding methods. Compounding with a finite impulse response is used for more versatile compositing. The compounding is adaptive, such as through adapting the image regions, weighting, or type of compounding as a function of correlation, location within the image, estimated motion or combinations thereof. A user warning is provided as a function of the correlation between images.

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 plurality of piezomaterial bodies, such as panels or slices, are merged together to form a larger piezomaterial body. For example, a 0.75×22 cm polycrystalline piezomaterial body is formed, where the distances are along lateral or footprint dimensions. The thickness of the piezomaterial body is substantially less than either of the distances along first and second lateral dimensions that define the footprint. Preferably, each piezomaterial body has a panel shape, and a plurality of panels are merged to form a large multi-panel.

摘要： A method and system for mapping surface data onto a geometrical representation of a structure for 3D imaging is provided. A boundary of a structure is determined from one type of data, such as Doppler energy data. Another type of data, such as B-mode data, representing the boundary or an area adjacent the boundary is extracted or identified. The B-mode data is then rendered as a function of the boundary, such as by texture mapping the B-mode data onto or adjacent the boundary. As the user examines the structure representation, the texture mapped data may provide texture details based on an optimally determined representation. The boundary may alternatively be used to select data for volume rendering.

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.
摘要翻译：提供了使用不透明度调制产生三维表示的方法和系统。与3D体数据集中的每个数据相关联的不透明度水平被控制为至少一个多普勒参数（诸如方差）的函数。高度差异的区域被赋予比低方差区域更高的不透明度水平。对于多普勒速度图像，与高方差相关联的速度比不稳定的速度更不透明地显示，从而强调更不透明的区域。更透明的速度（即与低方差相关的速度）仍然有助于图像并被显示。其他多普勒参数可用于图像，如能量，组织运动或方差。此外，可以使用其他多普勒参数来控制不透明度，例如速度，能量或组织运动。

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.
