20090010391Radiation Image Capturing System - The present invention relates to a radiation image capturing system. A radiation detector of a radiation detecting cassette detects a radiation that has passed through a patient, and an accumulated exposed radiation dose calculator calculates an accumulated exposed radiation dose by accumulating radiation image information detected by the radiation detector, at every image capturing. The calculated accumulated exposed radiation dose is transmitted, together with cassette ID information, to a console. In the console, a status determining unit compares the accumulated exposed radiation dose with an allowable accumulated exposed radiation dose for the radiation detecting cassette to determine the status of the radiation detecting cassette, and issues a warning based on the determined status.01-08-2009
20090026377Cassette - 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.01-29-2009
20090026380CASSETTE AND RADIATION IMAGE CAPTURING SYSTEM - A radiation detecting cassette houses therein a detector for detecting a load applied to the radiation detecting cassette when a patient has moved. It is determined whether or not the patient has moved in an image capturing process based on the load detected by the detector. If it is judged that the patient has moved, then a warning is displayed, and a radiation image of the subject is inhibited from being captured.01-29-2009
20090026391RADIATION IMAGE CAPTURING SYSTEM - A radiation image capturing system detects the position of a radiation detecting cassette disposed below a patient and the position of a radiation source for emitting a radiation, based on the differences between the propagation times of radio waves emitted from an antenna device to an image capturing apparatus and the radiation detecting cassette. Based on the detected positions, the relative positions of the image capturing apparatus and the radiation detecting cassette are calculated, and then compared with each other by a position determining unit to judge how the image capturing apparatus is positioned with respect to the radiation detecting cassette. If the image capturing apparatus is not positioned in head-on facing relation to the radiation detecting cassette, then a warning is issued, and an actuating mechanism moves the image capturing apparatus to an appropriate position.01-29-2009
20090026392RADIATION IMAGE CAPTURING SYSTEM - 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.01-29-2009
20090032745RADIATION IMAGE CAPTURING SYSTEM - 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.02-05-2009
20090257564RADIATION IMAGE CAPTURING SYSTEM - A radiation image capturing system detects the position of a radiation detecting cassette disposed below a patient and the position of a radiation source for emitting a radiation, based on the differences between the propagation times of radio waves emitted from an antenna device to an image capturing apparatus and the radiation detecting cassette. Based on the detected positions, the relative positions of the image capturing apparatus and the radiation detecting cassette are calculated, and then compared with each other by a position determining unit to judge how the image capturing apparatus is positioned with respect to the radiation detecting cassette. If the image capturing apparatus is not positioned in head-on facing relation to the radiation detecting cassette, then a warning is issued, and an actuating mechanism moves the image capturing apparatus to an appropriate position.10-15-2009
20100148081Cassette - 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.06-17-2010
20100156593Radiation image capturing system - 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.06-24-2010
20100202589X-ray image capturing and interpretation system with cassette and mobile X-ray image capturing apparatus - 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.08-12-2010
20100208871Bed for capturing radiation image and radiation image capturing system - 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.08-19-2010
