  • Patent number: 6668036
    Abstract: A method and an apparatus for processing data enables to display a preview image rapidly in case of processing large volume of data. Index data are generated by rendering the large amount of bit map data and stored in addition to the three-dimensional bit map data. By means that the two-dimensional image resulted from the rendering process is made prepared in advance before accepting the user's command for display and edit, the preview of the content of the data can be displayed rapidly at real-time when the user issues the command interactively.

  • Publication number: 20020154729
    Abstract: An X-ray sensor signal processor including capacitors 114 for removing DC components (dark currents) from output signals of semiconductor sensors 21 to 2n detecting pulse-like X-rays passed through an object, and integrators (each of which is constituted by a combination of an operational amplifier 115, a resistor 116 and a capacitor 117) for integrating the output signals of the X-ray sensors after removal of the DC components by the capacitors 114. By this, a value proportional to the average number of photons in X-rays can be obtained even in the case where a small number of incident photons are given, and an X-ray CT system using the X-ray sensor signal processor.
