摘要： A device and method for producing clinically useful hardcopy or archived records from a real-time imaging system includes a controller which monitors variable settings on the system effecting display monitor images. The controller then compensates the signal sent to the hardcopy recorder or archiving device via gamma curve or Look Up Table (LUT) application and/or directly through recorder brightness and contrast controls.

摘要： An information recording medium suitable for optical discs such as DVD-RAM is provided for integrated management of data as objects in different kinds of AV formats. Also, an apparatus is provided for data recording and playing to the medium. The medium stores management information including program chain information (PGC information) defining the playback order of the objects, and object information containing information relevant to the objects. The object information has general information of the object, attribute information and a map associating a playback time point of the object with an address on the optical disc of a component of the object to be played. The PGC information has cell information including information about type of object, identification information. The order of the cell information in the PGC information corresponds to the order in which the objects are played back.

摘要： A method and apparatus are provided for interpolating image lines from ultrasonically obtained scanlines of an image region. The interpolated lines are preferably formed one-quarter and three-quarters of the distance between each pair of received scanlines by combining weighted samples of the adjacent scanlines in proportion to their distances from the interpolated lines. The received scanlines are preferably formed by a beamformer which samples the received lines at quadrature phases of the scanhead center frequency and filters the samples by combining successive samples of a related phase. The image lines are scan converted by computing a grid of weighted values between each pair of image lines, and using the closest value for each pixel in the ultrasound image.

摘要： Apparatus for creating a video display from information generated by acoustically scanning a reflecting boundary circumferential of a borehole. A downhole tool generates a first signal each time a rotating transducer therein passes through magnetic north. Acoustic pulses emitted from the transducer are radially transmitted toward a borehole reflecting boundary. At least a portion of each pulse is reflected back to the transducer where the same is detected and converted to an electrical pulse representative of the reflected acoustic pulse. The peak of each electrical pulse is detected and the value digitized. A series of different addresses is associated with each digital value from a single 360.degree. borehole scan and the same are accumulated in a RAM with each digital value being stored therein at its associated address. A central processing unit selects a block of video memory locations in a video memory responsive to the magnetic north signal. The data stored in the RAM is transferred directly to the video memory by applying the RAM addresses, as the data is read out thereof, to the video memory thus transferring the data to the selected block of video memory locations. An address generator is provided for rapidly reading data from the video memory for generating a video display therefrom.
