    Abstract: A method and device that provides independent temperature control of x-ray detector crystals, either singly or in small groups. In addition to a thermal control network for the crystals, electronic devices are associated with each detector crystal and are independently cooled using Peltier devices so that lifetime and reliability are maximized. In most operating environments the ambient temperature is less than the operating temperature of the detector crystals. In these situations, the heat removed from the electronics can be used to heat the detector crystals, resulting in efficient operation.

  • Patent number: 7959303
    Abstract: When a position detector detects that the position of a spot on a projection plane designates a non-projection region, the level of a driving signal of a laser is corrected. Specifically, the correlation between the quantity of laser light detected by a light-receiving portion and the level of the driving signal of the laser in accordance with prescribed data is detected. Then, the characteristic value of the laser indicated by the detected correlation is compared with the characteristic value at room temperature stored beforehand to indicate the correlation between the quantity of light emitted by the laser at room temperature and the level of the driving signal. Then, based on the comparison result, the level of the driving signal of the laser in accordance with image data is corrected.

  • Patent number: 7928402
    Abstract: A radiation image detector includes a radiation-image-detector main body and a vacuum container. The radiation-image-detector main body generates charges by irradiation with an electromagnetic wave for recording that carries a radiation image and records the radiation image by accumulating the charges. The vacuum container is sealed to store the radiation-image-detector main body in a vacuum.

  • Patent number: 7897933
    Abstract: A radiation image capturing apparatus includes a cooling mechanism for causing cooling medium to flow from a rear surface side to a radiation detector to a front surface side of radiation detector through a narrow space formed between an end of the radiation detector and a casing for housing the radiation detector. It is therefore possible to cool the narrow space, as well as regions in the vicinity of the narrow space, with the cooling medium and to discharge the cooling medium from the front surface side of the radiation detector.

  • Patent number: 7847987
    Abstract: A method is disclosed as including scanning a first pixel of an image with a primary scanning line of a sensor, and scanning a second pixel of the image with a secondary scanning line of the sensor, wherein the first pixel is separated from the second pixel by a pitch of one or more scan lines. A compensation value is determined for one or more pixels of the image, wherein the compensation value is determined based, at least in part, on a mathematical operation comprising pixel values associated with the first and second pixels and the pitch. The method further includes compensating the one or more pixel values based, at least in part, on the compensation value, wherein the compensation value compensates for a reflection of light between the first and second scanning lines when the first and second pixels are scanned.
