摘要： A method of generating data compatible with forming a three-dimensional ultrasonic image includes selecting different frame rates for generating patterns of image information and frames of non-imaging information, such as motion information. The frame rates may be independently determined, based upon the desired characteristics of the two types of frames. Typically, image frames and motion frames are formed concurrently, with the formation of each motion frame overlapping the formation of more than one image frame, i.e., motion frames have a lower frame rate than image frames. After a sufficient number of image and motion frames have been generated, the image frames and the motion data are spatially coordinated to provide a three-dimensional flow image of a region of interest. In one approach, the spatial coordination of motion frames is implemented by incorporating the motion frames in a non-parallel relationship with the image frames. In a more accurate approach, the motion information is incorporated on a value-by-value basis into the image frames.

摘要： Methods and systems for a user to create a custom menu for medical imaging are provided. To maximize the ease of use and increase user efficiency, the user interface is tailored to a particular user or for a certain application. The user selects from various imaging parameters in a preprogrammed user interface displayed on a monitor or other display device. The selection is by collecting the desired items or by discarding undesired items. After selection, the desired items are displayed in a customized display state. This customized display state can be labeled and stored for later use. An assignable key is also provided. Imaging functions, such as a type of B-mode or Doppler imaging, are assigned to the key. Different or new functions may be later assigned to the key as the most used imaging functions change. Any customization may be different for different users of the same system, such as by saving the customization related to a log-on procedure.

摘要： A method for creating ultrasound images determines if an ultrasound transducer is moving by more than a predetermined amount by obtaining two conventionally focused images D.sub.K-1 and D.sub.K. Each image is divided into a series of sections. An image processor searches the previous frame D.sub.K-1 for data points found in the current frame D.sub.K. Movement vectors are defined for each section that describe how the data points of a section move from the previous frame D.sub.K-1 to the current frame D.sub.K. The movement vectors are then applied to sections of a previously displayed adaptively focused frame I.sub.K-1 in order to create a translated adaptively focused frame I.sub.K-1'. A new adaptively focused frame is created by averaging the current adaptively focused frame A.sub.K with the translated frame I.sub.K-1'.

摘要： An ultrasonic imaging system and method is described in which the actual dimensions of images of tissue acquired with a moving transducer (22) are displayed. Since an image is distorted based upon the direction a transducer probe moves relative to the acoustic scanning direction of the transducer (22), the probe motion direction and the acoustic scanning direction are initially determined. If the probe is moving in the same direction as the scanning direction, the acoustic beam scanning speed of the moving probe relative to the tissue is determined by summing the acoustic beam scanning speed without probe motion with the probe speed. If the probe is moving in the opposite direction as the scanning direction, the acoustic beam scanning speed of the moving probe relative to the tissue is determined by taking the difference between the acoustic beam scanning speed without probe motion and the probe speed. The actual width of the image as represented in each pixel of a frame (32) acquired while the probe is moving is derived based upon a ratio of the acoustic beam scanning speed of the moving probe relative to the tissue to the acoustic beam scanning speed without probe motion. Finally, the actual dimensions of the image are displayed based upon the derived width of the image as represented in each pixel of the frame (32).
摘要翻译：描述超声成像系统和方法，其中显示用移动换能器（22）获取的组织的图像的实际尺寸。由于图像根据换能器探针相对于换能器（22）的声波扫描方向移动的方向发生变形，因此初始确定探头运动方向和声波扫描方向。如果探头沿与扫描方向相同的方向移动，则移动探针相对于组织的声束扫描速度是通过将探针运动与探针速度无关的声束扫描速度求和来确定的。如果探头沿与扫描方向相反的方向移动，则通过取得探头运动的声束扫描速度和探头速度之间的差来确定移动探针相对于组织的声束扫描速度。基于移动探针相对于组织的声束扫描速度与声束扫描速度的比率导出在探头移动时获取的在帧（32）的每个像素中表示的图像的实际宽度，而没有探头运动。最后，基于在帧（32）的每个像素中表示的图像的导出宽度来显示图像的实际尺寸。
