Patent number: 9036945Abstract: A medical image handling system includes a monitor for displaying a medical image, an input device for inputting an image reading report corresponding to the medical image displayed on the monitor, and a processor. The processor judges the presence or absence of an image reading report corresponding to the medical image displayed on the monitor, and restricts a change of the medical image in a case where the image reading report is judged as being absent.Type: GrantFiled: November 15, 2011Date of Patent: May 19, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Koji Takekoshi, Akira Tago, Makoto Sato, Keiichi Sakai, Tsukasa Sako, Kazuhiko Takahashi, Muling Guo

Patent number: 8849068Abstract: An image management system, image management method and program are provided that can favorably manage images for displaying images that underwent optimization processing or images for creating and displaying difference images in which the generation of artifacts is suppressed. An image from image generator 100 is input to server 109 and stored in storage device 105. The system then determines whether an image including attendant information that is the same as that of the input image is already registered in the system. When such an image is not already registered, attendant information included in the input image is read out and newly registered in association with the input image. In contrast, when an image including attendant information that is the same as that of the input image is registered in the system and the attendant information is registered, information indicating the fact that the image was input is registered.Type: GrantFiled: March 24, 2006Date of Patent: September 30, 2014Assignee: Canon Kabushiki KaishaInventors: Masahiro Abe, Keiichi Sakai, Koji Takekoshi, Naoki Yamada

Patent number: 8401265Abstract: An anti-aliasing filter comprised by a first filter kernel is applied to the medical image data so as to obtain filtered image data. The filtered image data is downsampled so as to obtain decimated image data, and pixel resolution of the decimated image data is approximately one half of pixel resolution of the image data for the medical image. The decimated image data is upsampled and an interpolation filter is applied so as to obtain interpolated image data. The interpolation filter is comprised by a second filter kernel, and the size of the first kernel is smaller than the size of the second filter kernel. Pixel resolution of the interpolated image data is approximately equal to pixel resolution of the medical image data. Difference image data between the interpolated image data and the medical image data for the medical image is obtained, and the difference image data is displayed.Type: GrantFiled: May 10, 2010Date of Patent: March 19, 2013Assignee: Canon Kabushiki KaishaInventors: Manoj Mathew, Keiichi Sakai

Patent number: 8238682Abstract: A thinned output image is generated from an input image. Values of pixels surrounding a pixel of interest in the input image are determined, and first and second neighboring pixel patterns surrounding the pixel of interest are established based on the values of the pixels surrounding the pixel of interest. The first neighboring pixel pattern may be compared to each of a set of purge patterns to determine whether to eliminate the pixel, and the second neighboring pixel pattern may be compared to each of a set of conservation patterns to determine whether to conserve the pixel. The comparisons to the purge and conservation patterns are performed for each pixel independently, and in parallel for all pixels of the input image.Type: GrantFiled: December 23, 2008Date of Patent: August 7, 2012Assignee: Canon Kabushiki KaishaInventors: Manoj Mathew, Keiichi Sakai
