    摘要: A 3-D medical diagnostic ultrasonic imaging system corrects the elevational position of individual pixels based on the elevational motion of the transducer probe and the azimuthal position of individual pixels. In this way, the correct spatial position and orientation of multi-frame, sequentially required images is obtained, and 3-D volume reconstruction is made more accurate. Optionally, the acquired images and the measure of transducer in-plane translation and rotation are also corrected for azimuthal motion of the transducer.

    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.
