According to this method, it is possible to produce biochemical analysis data having high quantitative characteristics by photoelectrically detecting light emitted from a plurality of light releasable regions even in the case where the plurality of light releasable regions labeled with a labeling substance are formed in a sample at a high density.Type: GrantFiled: June 20, 2002Date of Patent: March 25, 2008Assignee: FUJIFILM CorporationInventors: Hitoshi Shimizu, Nobuhiko Ogura

Patent number: 7329890Abstract: A method for scanning and processing computed radiography x-ray images in order to maximize the usage of cassette options. The storage phosphor radiography imaging method of the invention employs a cassette comprising a storage phosphor screen adapted to be exposed to x-rays to store a latent x-ray image in the screen and read using a reader. The method includes the steps of: associating cassette information with the cassette using an identification member affixed to the cassette or storage phosphor screen, the cassette information comprising information relating to characteristics of the cassette relevant to the reading of the screen by the reader; prior to reading the exposed storage phosphor screen to generate a digital image signal, scanning the identification member to obtain the cassette information; and reading the exposed storage phosphor screen in accordance with the cassette information to generate the digital image signal.Type: GrantFiled: September 19, 2005Date of Patent: February 12, 2008Assignee: Carestream Health, Inc.Inventors: Lynn M. Fletcher-Heath, Francisca Sugiro, Xiaohui Wang

Patent number: 7329891Abstract: In order to improve the picture quality of X-rays, a read-out control is provided for controlling a read-out device such that a first storage phosphor layer, which has a first thickness d1, is read out by the read-out device controlled in a first read-out mode, and a second storage phosphor layer, which has a second thickness d2 which is greater than the first thickness d1, is read out by the read-out device controlled in a second read-out mode, the second read-out mode being different from the first read-out mode. The scan parameters of the read-out device set in the first read-out mode are different from the scan parameters set in the second read-out mode in at least one scan parameter. The scan parameters are, for example, the size of the pixels, a pulse duration and/or intensity and/or width of a focus range of stimulation light, integration time and/or feed time of the detector.Type: GrantFiled: February 9, 2006Date of Patent: February 12, 2008Assignee: Agfa-Gevaert Healthcare GmbHInventors: Jörg Frankenberger, Robert Fasbender, Clemens Herrmann, Johan Lamotte, Stephan Mair, Horst Scherer

Patent number: 7304322Abstract: An image reading apparatus includes a casing accommodating therein a heating mechanism for heating the interior of the casing. The heating mechanism has a heating body mounted on a guide plate along which a stimulable phosphor sheet is fed. When supplied with electric current, the heating body is heated to heat the guide plate to a predetermined temperature. An air blower is disposed in confronting relation to the heating body and is energized to circulate heated air inside the casing. A temperature detector detects the atmospheric temperature inside the casing, and when the detected atmospheric temperature becomes higher than a reference temperature preset in a controller, the controller stops supplying electric current to the heating body.Type: GrantFiled: March 9, 2005Date of Patent: December 4, 2007Assignee: FUJIFILM CorporationInventor: Akifumi Mamiya

Patent number: 7304321Abstract: A storage phosphor cassette for use in recording radiographic images of elongated objects. The cassette comprises a shell and a single storage phosphor plate. The shell includes first and second opposite open ends. The single storage phosphor plate is housed within the shell and is adapted to be at least partially removable from the shell through the first and second open ends. A radiation image of the elongate object can be read by extracting a first portion of the single plate through one of the two opposing ends of the cassette and scanning the first portion of the single storage phosphor plate to obtain a first partial image, and then extracting a second portion of the single plate through the other of the two opposing ends of the cassette and scanning the second portion of the single storage phosphor plate to obtain a second partial image. The first and second partial images can be combined to form the image of the elongate object.Type: GrantFiled: October 14, 2005Date of Patent: December 4, 2007Assignee: OREX Computed Radiography, Ltd.Inventor: Jacob Koren
