  • Publication number: 20140093029
    Abstract: Radiographic images for different imaging directions taken by applying radiation to a subject from the different imaging directions are obtained, and a plurality of first tomographic images having a first slice thickness are generated based on the obtained plurality of radiographic images and a plurality of second tomographic images having a second slice thickness that is greater than the first slice thickness are generated based on the radiographic images. Then, MinIP processing is applied to the first tomographic images to generate a MinIP image, and MIP processing is applied to the second tomographic images to generate a MIP image. Then, combining processing is performed using the MinIP image and the MIP image to generate a composite image.

  • Patent number: 8528901
    Abstract: A printer has a paper feed mechanism that can reliably balance the paper feed force of the paper feed roller and paper pressure roller on the left and right sides of the recording paper width. Using the self-centering action of a pressure lever fulcrum and adjustment of the position where an extension spring applies force, the paper feed mechanism of a printer can press the paper pressure roller that is supported by a pressure lever to a paper feed roller so that the paper pressure roller applies equal pressure at all points along the width of the paper feed roller, can balance the paper feed force applied by the paper feed roller and the paper pressure roller to the recording paper left and right widthwise to the paper, and can prevent the recording paper from meandering, skewing, and jamming.

  • Patent number: 8351822
    Abstract: One end of the cover unit of a printer is supported freely rotatably on the device case, and a rotating shaft is disposed with both ends supported freely rotatably on the distal end. A right pressure lever and an operating lever are supported on the right end of the rotating shaft, and a left pressure lever is supported on the left end. When the operating lever rotates, the right and left pressure lever rotate in the same direction through an intervening rotation transfer member extending widthwise to the device. When the operating lever rotates when the cover is closed, the left pressure lever contacts the device case before the right pressure lever . The right and left pressure lever are set so that their rotational positions are the same when the cover starts to rise due to deformation of the rotation transfer member.

  • Patent number: 8223222
    Abstract: Disclosed herein is a method of storing or transferring an image along with an image-processing parameter for processing the image. When storing or transferring a second image for storage or transfer which has a second resolution for storage or transfer differing from a reference resolution, a reference image-processing parameter set according to a reference resolution image having the reference resolution is corrected based on a difference between the reference resolution and the second resolution, so that it becomes a second parameter corresponding to the second image. The second parameter obtained by the correction is stored or transferred along with the second image.

  • Patent number: 8191984
    Abstract: A recording medium detection method uses transmission and reflection photosensors to correctly detect if a recording medium having labels affixed to a liner is in the transportation path. The label printer has a reflection photosensor and a transmission photosensor disposed to the transportation path at positions separated the distance between the labels. Labels on the recording medium can always be detected by either or both the reflection photosensor and the transmission photosensor. Because the reflection photosensor is downstream from the transmission photosensor, a situation in which a black mark is at the detection position of the reflection photosensor and reflection is not detected and only the liner is at the detection position of the transmission photosensor and transmission of the detection beam is detected is avoided. Detecting transmission without detecting reflection of the detection beam therefore only occurs when the recording medium is not in the transportation path.
