Patent number: 8536535Abstract: In a radiation image capturing system, prior to radiation image capturing operation, the radiation image capturing apparatus repeats on an alternate basis, a step of reading leak data and a step of resetting each of the radiation detection elements, wherein the step of reading leak data is performed by turning off all switch units, allowing a reading circuit to perform cyclic reading operations under this condition and converting electric charge leaking out of radiation detection elements through the switch units into the leak data, thereby detecting a start of irradiation based on the leak data having been read out. The image processing apparatus analyzes a profile of image data along the extension of signal lines of the radiation image capturing apparatus, and identifies a range of the image data where a defect has occurred, whereby the image data in the identified range is corrected.Type: GrantFiled: February 10, 2012Date of Patent: September 17, 2013Assignee: Konica Minolta Medical & Graphic, Inc.Inventors: Kouji Amitani, Tatsuya Takagi, Ryohei Ito

Patent number: 8254522Abstract: A dynamic image, of a quality required for diagnosis that does not increase the radiation dosage of a person being imaged, can be captured by a dynamic imaging system that includes an imaging console which has a control unit. The control unit analyzes at least one of the frame images captured at an initial state of dynamic imaging, calculates an index indicating the quality of the image, and calculates, by using the calculated index, an upper limit frame rate fsup such that the index indicating the quality of the frame image captured by the dynamic imaging is below a determined reference value. The frame rate used for dynamic imaging is determined according to the calculated upper limit frame rate fsup and a lower limit frame rate finf required to diagnose the dynamic state of the imaged region. An imaging device may image the person at the determined frame rate.Type: GrantFiled: February 19, 2009Date of Patent: August 28, 2012Assignee: Konica Minolta Medical & Graphic Inc.Inventor: Tatsuya Takagi

Publication number: 20100183202Abstract: To provide a brain-image diagnosis supporting method or the like. The method is a statistical evaluation method excluding the subjective judgment of an examiner, and enables image diagnosis. The method can present stable judgment criteria with respect to data on brain images imaged by a predetermined method in order to discriminate difficult diseases to diagnose. The method is also effective with respect to relationships which can not be always explained with a simple linear relationship, for example, the relationship between data on brain images imaged by a predetermined method and a disease which is a variable. By applying a predetermined nonlinear multivariate analysis method to data on brain images of a plurality of examinees imaged by a predetermined method and by classifying the data, image diagnosis support using a computer performed with respect to the data on brain images is performed. For example, SOM method is applied as a predetermined nonlinear multivariate analysis method.Type: ApplicationFiled: November 5, 2007Publication date: July 22, 2010Applicants: FUJIFILM RI PHARMA CO., LTD., Osaka University, The University of TokushimaInventors: Yoshitake Takahashi, Tatsuya Takagi, Kousuke Okamoto, Masafumi Harada

Publication number: 20030007180Abstract: In a printing control system for printing on non-standard media having a long page length, a host device divides the print data of a single physical page into a plurality of blocks representing independent logical pages, and sends the print data blocks to a printing device together with information indicating the existence of multiple logical pages. The printing device generates printable image data blocks from the print data blocks, and prints the image data blocks on the physical page according to the information added by the host device. Since the printing device can process the print data blocks one by one, the physical length of the page is not constrained by the memory capacity of the printing device.Type: ApplicationFiled: June 27, 2002Publication date: January 9, 2003Applicant: Oki Data CorporationInventors: Koji Urasawa, Tatsuya Takagi
