    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: An ultrasonic imaging system includes an ultrasonic transducer having an image data array and a tracking array at each end of the image data array. The tracking arrays are oriented transversely to the image data array. Images from the image data array are used to reconstruct a three-dimensional representation of the target. The relative movement between respective frames of the image data is automatically estimated by a motion estimator, based on frames of data from the tracking arrays. As the transducer is rotated about the azimuthal axis of the image data array, features of the target remain within the image planes of the tracking arrays. Movements of these features in the image planes of the tracking arrays are used to estimate motion as required for the three-dimensional reconstruction. Similar techniques estimate motion within the plane of an image to create an extended field of view.

    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.
