Exposure anticipation circuit |
June 28, 1988 |
| A method and apparatus for reducing delay times between successive x-ray images in a medical x-ray diagnostic system in which delay times are a function of the time required to transport film in a camera apparatus. The camera is used to record images on an image display apparatus. The de |

Method and means for automatically variably controlling display parameters |
January 7, 1986 |
| The display Gray level in a video display of a computer tomography system is changed at a rate which is non-linearly proportional to the rate of pulses generated by a manually operated control such as a track ball thereby accelerating change in the Gray level when a large change is d |

Cursor generator for use in computerized tomography and other image display systems |
March 31, 1981 |
| A composite video signal waveform is fed through a video mixer and to a video monitor for displaying a raster scanned image on its screen. Signals are also fed through the mixer for causing a cursor having distinctive light intensity to be overlayed on the image. Programs for defining |

Device for delineating zones in a video image display |
January 13, 1981 |
| Data derived from multiple x-ray views of a body layer is processed in accordance with an image reconstruction algorithm by a central processing unit (CPU) to result in a matrix of digital data corresponding with picture elements (pixels) which are for being displayed on a tv or video |

CT number identifier in a computed tomography system |
August 8, 1978 |
| In computed tomography, a computer calculates CT numbers corresponding with the X-ray attenuation by elemental volumes in a body undergoing an X-ray beam scan. Analog signals corresponding with the sequence of CT numbers modulate a raster scanned cathode ray tube to produce a display of |

Method and apparatus for obscuring the raster lines in a photograph of a video monitor screen |
June 20, 1978 |
| Raster lines are obscured in a photograph of an image displayed on a video monitor. A photographic film is used as an integrating mechanism. The TV raster is vertically displaced during the camera shutter open time a total deflection of one horizontal line, thus blending the information |
