  • Patent number: 10335098
    Abstract: In a panoramic imaging apparatus, a panoramic image is displayed on a monitor. The panoramic image is an image in which an overall dentition is in optimal focus, or an image in which a region of interest that is a portion of the image of the overall dentition is in optimal focus. Both images are reconstructed from frame data that has been collected by an initial first scan. Feature points of one or more teeth and a supporting portion that supports the tooth in the dentition in the panoramic image displayed on the monitor are designated. A length based on the positions of the designated feature points is measured in the panoramic image. The degree of loss in alveolar bone that supports the tooth is analyzed based on the measured length. The analysis information is provided to a dentist as check information regarding periodontal disease.

  • Patent number: 7944461
    Abstract: A heating device capable of evenly heating a thermal recording medium without increasing the cost of the device is disclosed. The heating device evenly heats the recording surface of a thermally-reversible recording card by conducting the heat energy transferred from a heat generating member by way of a heating member, made of aluminum having high heat conductivity and high heat capacity characteristics. By this feature, it becomes possible to accurately erase the information recorded on the recording card and to use an inexpensive heat generating member as the heat generating member.

  • Patent number: 7671879
    Abstract: An information recording apparatus enables information to be recorded in a thermosensitive recording medium accurately while preventing the development of skew. When a rewritable medium is conveyed to a recording unit, the rotation of the rewritable medium and its position with reference to an axis are adjusted. Specifically, the rewritable medium is held between guide pins to such an extent as not to warp the rewritable medium while the medium is sandwiched between a clamper and a conveyance tray, until the rewritable medium reaches the recording unit. Thus, the rewritable medium is delivered to the recording unit with an adjusted posture, allowing the recording unit to record information in the rewritable medium without the development of skew in the rewritable medium.
