Patent number: 7737427Abstract: A signal detector detects signals transmitted from signal generators disposed in a radiation detecting cassette, and a distance calculator calculates the distance between a radiation source and a radiation detector based on the signals detected by the signal detector. A determining unit determines whether the detected distance matches a predetermined distance from the radiation source to the radiation detector when a radiation image is captured. If the detected distance does not match the predetermined distance, the determining unit outputs, to a warning unit, a warning signal indicating that the detected distance does not match the predetermined distance, and also outputs a control signal for equalizing the detected distance with the predetermined distance, to a radiation source movement controller.Type: GrantFiled: July 29, 2008Date of Patent: June 15, 2010Assignee: FUJIFILM CorporationInventors: Eiichi Kito, Tsuyoshi Tanabe, Takuya Yoshimi, Takeshi Kuwabara, Kazuharu Ueta, Makoto Iriuchijima, Yasunori Ohta

Patent number: 7737410Abstract: Digital images or the charge from pixels in light sensitive semiconductor based imagers may be used to detect gamma rays and energetic particles emitted by radioactive materials. Methods may be used to identify pixel-scale artifacts introduced into digital images and video images by high energy gamma rays. Statistical tests and other comparisons on the artifacts in the images or pixels may be used to prevent false-positive detection of gamma rays. The sensitivity of the system may be used to detect radiological material at distances in excess of 50 meters. Advanced processing techniques allow for gradient searches to more accurately determine the source's location, while other acts may be used to identify the specific isotope. Coordination of different imagers and network alerts permit the system to separate non-radioactive objects from radioactive objects.Type: GrantFiled: May 20, 2008Date of Patent: June 15, 2010Assignee: Advanced Fuel Research, Inc.Inventor: Eric P.

Patent number: 7732778Abstract: The invention intends to be able to perform a gain correction fully adequately. Hence, at the time of radiographing an object, a gain correction of the object image is performed based on a gain correction image (XRc1) derived by performing a light reset. On the other hand, at the time of radiographing an object, when a light reset is not performed, a gain correction of the object image is performed based on a gain correction image (XRc2) derived without performing the light reset.Type: GrantFiled: December 7, 2006Date of Patent: June 8, 2010Assignee: Canon Kabushiki KaishaInventors: Keigo Yokoyama, Tadao Endo, Toshio Kameshima, Tomoyuki Yagi, Katsuro Takenaka

Patent number: 7728299Abstract: Edge portions of detection electrodes, such as a first linear electrode and a second linear electrode, that include the side surfaces of the detection electrodes and parts of surfaces of the detection electrodes, the surfaces continuing from the side surfaces and facing a photoconductive layer for recording, are covered with dielectrics. Further, surfaces of the detection electrodes and the dielectrics are coated with an anti-crystallization layer to prevent crystallization of a photoconductive layer for readout. At this time, the surfaces of the electrodes are smoothly covered with the dielectrics at angles ? of contact of 5 to 60 degrees so that no bump is present, thereby preventing generation of a crack in the anti-crystallization layer on the dielectrics and the electrodes. Accordingly, crystallization of the photoconductive layer for readout, which is induced by injection of charges from the edge portions of the detection electrodes or the like, is prevented.Type: GrantFiled: August 29, 2008Date of Patent: June 1, 2010Assignee: FUJIFILM CorporationInventors: Kaku Irisawa, Yasuhisa Kaneko, Masaharu Ogawa

Patent number: 7718973Abstract: A radiation imaging apparatus comprises a read unit reading electric signals from radiation detecting elements that are arranged two-dimensionally and that convert incident radiation into electric signals. A control unit controls the radiation detecting unit such that a first radiation detecting element is switched into a state in which charge generated therein cannot be taken out (a “senseless state”) and a second radiation detecting element is switched into a state in which it charge generated therein by incident radiation can be taken out (a “sensible state”), and a signal processing unit performs a subtraction processing such that the electric signal from the radiation detecting element that is in the senseless state is subtracted from the electric signal from the radiation detecting element that is in the sensible state, to reduce conspicuous line noise in an image by means of a relatively simple configuration.Type: GrantFiled: March 7, 2007Date of Patent: May 18, 2010Assignee: Canon Kabushiki KaishaInventors: Tadao Endo, Toshio Kameshima, Tomoyuki Yagi, Katsuro Takenaka, Keigo Yokoyama

Patent number: 7712959Abstract: A radiation detecting cassette is disposed in a desired position between a bed and a patient in an operating room. After a detector-side connector and a bed-side connector are connected to each other by a cable, an image capturing apparatus captures and records radiation image information of the patient in a radiation detector. The recorded radiation image information is transmitted from a transceiver of the bed to a console by way of wireless communications, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.Type: GrantFiled: August 25, 2008Date of Patent: May 11, 2010Assignee: Fujifilm CorporationInventors: Tsuyoshi Tanabe, Eiichi Kito, Takuya Yoshimi, Takeshi Kuwabara, Kazuharu Ueta, Makoto Iriuchijima, Yasunori Ohta
