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.
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.
Abstract:
A radiation detecting cassette and a radiation image capturing system. 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.
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.
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.
Abstract:
A radiation detecting cassette has a casing including a first flat plate for facing a patient and a second flat panel for facing a surgical table. 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.
Abstract:
A radiation detecting cassette includes a casing having first through fourth display units mounted on respective side walls thereof for displaying ID information of a patient, etc. The casing also has first detectors on the respective side walls for detecting obstacles facing the first through fourth display units and second detectors on the respective side walls for detecting loads applied to the casing near the first through fourth display units. Based on detected results from the first and second detectors, at least one of the first through fourth display units which is not covered by the patient is selected to display the ID information of a patient, etc.

Abstract:
When a cassette transceiver starts to transmit radiation image information to a console transceiver, the cassette transceiver transmits a test radio wave, and the console transceiver calculates a minimum transmission radio-field intensity of said cassette transceiver which is required to receive the radiation image information from a received intensity of said test radio wave, and transmits a command radio wave representing the calculated minimum transmission radio-field intensity as a command to said cassette transceiver. The cassette transceiver is thus capable of transmitting the radiation image information at the commanded minimum transmission radio-field intensity. The consumption of electric power for transmitting the radiation image information from the cassette transceiver to the console transceiver is thus minimized.
