  • Patent number: 7834322
    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: 20100283583
    Abstract: A radiation image capturing method, a radiation image capturing system, and a radiation information system are provided. In the present invention, a console checks a cassette ID (specified cassette ID) sent from an RIS server as the cassette ID of a radiation detecting cassette that is planned to be used to capture a radiation image, and a cassette ID (actual cassette ID) that is read by the console from a radiation detecting cassette which is placed in an operating room or an image capturing room and which is to be actually used to capture a radiation image, with each other. Based on the result of the cassette ID check, the console determines whether to permit a radiation image to be captured or not.

  • Patent number: 7829859
    Abstract: Power supply switches are disposed on respective side walls of a casing of a radiation detecting cassette, which are held out of contact with a patient when a radiation image of the patient is captured. When a surgeon or a radiological technician turns one of the power supply switches on or off, a battery starts or stops supplying electric power to a radiation detector, a cassette controller, and a transceiver.

  • Publication number: 20100271215
    Abstract: A radiation detecting cassette and a radiation image capturing system are provided. A radiation detecting cassette has a radiation detector for detecting a radiation having passed through a patient and converting the detected radiation into radiation image data, a transceiver for transmitting the radiation image data by way of wireless communications, a cassette controller for controlling the radiation detector and the transceiver, a power supply for energizing the radiation detector and the transceiver, and a remaining power supply power level detector for detecting a remaining power level RC [%] of the power supply. The cassette controller includes a data transmission and reception controller. The cassette controller stops transmitting the radiation image data by way of wireless communications and prioritizes the capturing of a radiation image when the detected remaining power level of the power supply is smaller than a predetermined threshold.

  • Publication number: 20100208871
    Abstract: 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 in a communication range selected by a selector of the bed, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.

  • Patent number: 7777193
    Abstract: The signal strength of communications of a cassette transmitter/receiver is set to be lower during transmission of confirmation image signals, that is, during readout of image signals from a radiation detector, than the signal strength of communications of the cassette transmitter/receiver at times other than during readout of image signals. This suppresses adverse influence imparted onto the image signals by wireless communication, and reduces the amount of noise generated in the image signals.

  • Publication number: 20100202589
    Abstract: A cassette allows radiation image information stored therein to be used immediately after an X-ray radiation image is captured in a patient's room, and a mobile X-ray image capturing apparatus incorporates such a cassette. The mobile X-ray image capturing apparatus has a cradle serving as a mount for receiving the cassette which has a radiation detector. The mobile X-ray image capturing apparatus captures a radiation image of the patient (subject) in the patient's room. The cassette serves as a mobile station. While the cassette (mobile X-ray image capturing apparatus) is moving, the radiation image information stored in the cassette is transmitted to a server via a transmitting and receiving terminal, a mobile hospital communication network, and a hospital LAN.

  • Publication number: 20100187427
    Abstract: A wireless communication control unit controls a transmitting and receiving apparatus so as to prohibit transmission of radiation image information to the outside by wireless communication or power supply from the outside to an electric power source by wireless communication in accordance with an exposure detecting signal from an exposure detecting unit or a conversion detecting signal from a conversion detecting unit. Thus, this can control the transmitting and receiving apparatus not to carry out, at the same period of time, the irradiation of a radiation (X) to a radiation detector, a conversion operation of the radiation image information in the radiation detector, and wireless communication by the transmitting and receiving apparatus.

  • Publication number: 20100156593
    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.

The first flat plate and the second flat panel are spaced from each other by a predetermined distance. The casing also includes a pair of first and second tapered side members disposed on respective side edges of the first and second flat plates. The first and second tapered side members are progressively tapered toward their distal ends. The first and second tapered side members house therein respective radiation shields, which in turn house therein a battery, a cassette controller, and a transceiver.

  • Patent number: 7737427
    Abstract: 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.

  • Patent number: 7732779
    Abstract: A radiation imaging system is equipped with a radiation imaging apparatus and a control apparatus. The radiation imaging apparatus reads out image signals from a radiation detecting section that detects radiation which has passed through a subject, and outputs the read out image signals as wireless signals. The control apparatus outputs predetermined control signals to the radiation imaging apparatus as wireless signals. A second wireless communicating section of the control apparatus decreases the signal strength of communications to be lower during readout of the image signals than at times other than during readout of image signals.
