20090039297 | Radiation 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. | 02-12-2009 |

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. | 02-19-2009 |
20090046834 | Radiation image capturing system and method of setting minimum transmission radio-field intensity in such radiation image capturing system - 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. | 02-19-2009 |
