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.

Cassette and radiation image capturing system

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.

Radiation detecting cassette and radiation image picking-up system

A 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 signal strength of communications of a cassette transmitter/receiver is set to be lower during readout of the image signals than the signal strength of communications of the cassette transmitter/receiver at times other than during readout of image signals.

Radiation imaging 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.

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.

Bed for capturing radiation image and radiation 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.

Radiation image capturing system

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.

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.

An image capturing system includes a cassette having a radiation detector, an image memory, and a cassette controller, an image capturing apparatus, a display device, and a host computer. The cassette controller comprises a capacity value transmitter for transmitting a capacity value of the radiation image information to the host computer before transmission process, and an image transmitter for transmitting the radiation image information. The host computer comprises an indicator controller for controlling the display device to display an indicator representing the capacity value received from the cassette as the upper limit, and a bar controller for controlling the display device to display a bar moving toward the indicator and having a length corresponding to the received capacity value of the radiation image information while the radiation image information is being received.

Radiation detecting cassette and medical 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.

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.

A radiation detecting cassette includes an IC card detector which detects insertion of an IC card in a slot, outputs a detection signal representing that the IC card is inserted in the slot, and reads ID information stored in the IC card. An ID checker of the radiation detecting cassette checks the ID information against ID information stored in a card ID memory. A power unit controller controls supply of electric power from a power unit to a radiation detector and/or components of the radiation detecting cassette based on a checking result from the ID checker.
