摘要： Motion artifacts are reduced for three- or four-dimensional imaging with a mechanically rocked array by determining a position of a scan within a volume as a function of velocity. A represented position within a volume of a mechanically rocked scan is determined. Differences in velocity associated with different scan plane positions are used to alter or adjust a scan position. For example, the start position for a transmit operation or the spatial location represented by previously acquired data is altered as a function of a corresponding velocity in the mechanical movement of the array. Variation in velocity results in different relative scan positions or adjustments within the volume. The velocity variation is determined in an open loop, such as from previously measured or expected velocity of the array, or from feedback from actual measured position and associated velocity of the array.

摘要： A computer-based video editing system provides software controlled wipes between scenes. These wipes may be the conventional horizontal, vertical, or clock type wipes used in video to transition from one scene to the next. Instead of being generated by conventional digital wave form generators, the wipes are generated as a bit map in computer memory, thus allowing the editor to design his own wipes as desired. The wipes are generated by comparators which have as their inputs line-by-line video data and computer controlled threshold data so as to control a video switcher to select between scenes as determined by the wipe pattern.
摘要翻译： 基于计算机的视频编辑系统在场景之间提供软件控制的擦除。 这些擦拭物可以是视频中用于从一个场景转换到另一个场景的常规水平，垂直或时钟类型的擦拭物。 代替由传统的数字波形发生器产生，擦拭物作为计算机存储器中的位图产生，从而允许编辑器根据需要设计自己的擦拭物。 擦除由比较器产生，比较器具有逐行视频数据和计算机控制的阈值数据，以便控制视频切换器在由擦除图案确定的场景之间进行选择。

摘要： A disk-assisted system for editing video tapes. Source material from video tapes is logged onto random access storage such as a hard disk drive using of a Macintosh-based computer system. At any one time, only a small portion of the tape material is stored as video frames on the computer disk. By software control, material is cached back and forth between the computer disk and the video tape. Thus editing is accomplished and an edit decision list constructed for compilation of the final video production. This provides the advantage of fast access time for editing of the material which is on the disk while allowing actual physical editing at the end of the project of the actual video tape material. The processes of logging the material onto the disk and editing the final tape are performed automatically.

摘要： Medical diagnostic ultrasound stereo imaging is provided. A medical diagnostic ultrasound system operable to scan a body with ultrasound is also operable to generate a three dimensional stereoscopic view of the body. The video processing unit and/or display device create the stereoscopic display.
