  • Patent number: 10866198
    Abstract: An IP cover having a light-shielding property is detachably mounted on an IP. The IP includes a stimulable phosphor layer on one surface thereof. The IP cover is mounted on the stimulable phosphor layer so as to be closely attached to the stimulable phosphor layer. The IP and the IP cover include notches, and a part of an inspection target is inserted into the notches at the time of inspection. An IP unit is mounted on a blade welded portion of an impeller. Radiation is applied from a radiation irradiation device and a radiation image of the blade welded portion is recorded on the IP as a latent image. The IP cover is detached from the IP unit and the IP is set on a template. The IP is set at an image reading position of a radiation image reading device by the template, and the radiation image is read.

  • Patent number: 10165998
    Abstract: A method and a system for determining an angle between two parts of a bone that are twisted relative to one another about the axis of a bone shaft. The system is particularly suitable for determining the antetorsion angle of a femur. In order to determine an antetorsion angle of a bone easily intraoperatively, a method with the following steps is proposed: establishing the position of a first orientation feature assigned to a first part of the bone, in particular a femoral neck axis, using an imaging method, establishing the position of a second orientation feature assigned to a second part of the bone, in particular a condyle tangent or a condyle plane, using an imaging method, and determining the angle, in particular the femoral antetorsion angle, from the positions of the two orientation features.

  • Patent number: 9602715
    Abstract: An imaging system is provided for a precision machine vision inspection or metrology system. The imaging system optical path includes a variable magnification lens portion and a variable focal length lens portion. The variable magnification lens portion includes various magnification states (e.g., 0.5× to 100×, using interchangeable lenses, or the like.) The variable focal length lens portion (e.g., including a tunable acoustic gradient index of refraction (“TAG”) lens) is operated at different focal length scanning frequencies depending on the magnification state. A TAG lens operated in this manner provides a relatively consistent range of focus (e.g., corresponding to a number of depths of field) with various magnification lenses, without limiting the effective numerical aperture of the imaging system.

    Abstract: The radiographic image conversion panel includes a recording layer formed of a first accumulative phosphor that is irradiated with a radiation as a first primarily exciting light beam to excite primarily and accumulate energy, and is irradiated with a first secondarily exciting light beam to excite secondarily and generate a stimulating light beam and a correction marker for detecting a position formed of a second accumulative phosphor that is irradiated with a second primarily exciting light beam to excite primarily and accumulate the energy, and is irradiated with a second secondarily exciting light beam to excite secondarily and generate light with a wavelength shorter than a wavelength of the first secondarily exciting light beam. The radiographic image acquisition system uses the radiographic image conversion panel.

  • Publication number: 20090039297
    Abstract: The power consumption of a battery for supplying electric power to a cassette having a radiation detector for detecting radiation image information is greatly reduced. When a cassette transceiver of the cassette starts transmitting the radiation image information to a console transceiver of a console, the cassette transceiver changes the gain of a variable-gain amplifier to change a transmission radio-wave intensity, and transmits a test signal at the changed transmission radio-wave intensity. When the console transceiver receives the test signal, the console transceiver transmits a reception acknowledgement signal generated by a reception acknowledgement signal generator. In response to the reception acknowledgement signal, the cassette transceiver sets its own transmission radio-wave intensity to a value at the time the cassette transceiver received the reception acknowledgement signal, and transmits the radiation image information at the set transmission radio-wave intensity.

  • Publication number: 20090032745
    Abstract: A transceiver of a radiation detecting cassette sends cassette ID information stored in a cassette ID memory to a transceiver of a console via a transceiver of an image capturing apparatus by way of wireless communications. An ID determining unit determines whether cassette ID information which matches the cassette ID information received by the transceiver is stored in a cassette ID memory or not. If the ID determining unit judges that both cassette ID information match each other, the transceiver sends the cassette ID information and an activation instruction signal to the transceiver by way of wireless communications.

  • Publication number: 20090026392
    Abstract: A transceiver of a radiation detecting cassette receives subject ID information from an RFID tag by way of wireless communications. An ID checker checks the subject ID information received by the transceiver against a plurality of subject ID information stored in an RFID memory. If the subject ID information received by the transceiver matches one of the subject ID information stored in the RFID memory, then the ID checker associates the matching subject ID information with a radiation dose that is stored in a dose storage unit and corresponds to the matching subject ID information.

  • Publication number: 20080237507
    Abstract: The radiation image recording system includes a radiation source irradiating a subject with radiation to record a subject's radiation image; a solid-state radiation detector detecting the radiation from the radiation source; a memory storing calibration information of the radiation image detected by the solid-state radiation detector; an image processor subjecting recorded data of the radiation image to image corrections based on the calibration information; stabilizing time monitor checking time elapsed since start of power application to the radiation detector; and a controller setting a recording mode of the radiation image based on information on the elapsed time. When the information on the elapsed time indicates that a specified stabilizing time has elapsed, the controller causes the radiation detector to undergo a calibration to acquire new calibration information and causes the memory to store the acquired new calibration information to which the stored calibration information is updated.

  • Patent number: 7355196
    Abstract: A stimulable phosphor sheet, on which a radiation image of an object has been stored, is scanned with stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored on the stimulable phosphor sheet during exposure of the stimulable phosphor sheet to radiation. The light, which is emitted by the stimulable phosphor sheet when the stimulable phosphor sheet is scanned with the stimulating rays, is detected, and an image signal representing the radiation image of the object is acquired. The scanning of the stimulable phosphor sheet with the stimulating rays is performed from an object image-carrying edge area, in which a radiation image pattern representing the object has been stored, the object image-carrying edge area being one of edge areas of the stimulable phosphor sheet.
